Research funding propels Team Science forward

Oregon State University is focused on big discoveries that drive big solutions. Many science faculty received grants last year in support of discovery-driven science, applied and transdisciplinary research science education and innovation in OSU’s priority research areas of integrated health and biotechnology, climate science and solutions, robotics, data science and AI, and clean energy and solutions. Below are some of the highlights—not including multi-year projects started before 2023.

Faculty honors

Astrophysicist Jeff Hazboun received a $73K Faculty Early Career Development award from the National Science Foundation. This prestigious NSF early career award is highly coveted by faculty! Hazboun’s project includes curriculum development and the implementation of a summer workshop in astrophysics-themed data analysis designed to foster inspired teaching, stimulate excitement in pulsar timing array research, facilitate the learning goals of undergraduate and graduate students, and support the community college students’ transition into four-year schools.

Mathematician Christine Escher received a $50,397 award from the NSF to host the Pacific Northwest Geometry Seminar series over three years at various Pacific Northwest universities. Escher is the principal organizer of the conference. This award supports meetings of the Pacific Northwest Geometry Seminar (PNGS), a regional meeting for researchers and educators of geometry, to be held at the University of British Columbia (2025), Seattle University (2026) and Lewis & Clark College (2027).

Integrated health & biotechnology

Materials scientist Kyriakos Stylianou, along with members of the College of Pharmacy and the College of Agricultural Science, received $2 million from the U.S. Department of Agriculture to develop improved ways of preventing stored potatoes from sprouting, particularly in the organic sector. Stylianou’s team studied nearly 200 different plant essential oils for their anti-sprouting effects. Oregon, Washington and Idaho produce more than 60% of the potatoes grown in the United States, and Pacific Northwest potato cultivation is a $2.2 billion industry.

Microbiologist Maude David is part of a multi-institution research team to receive a $4.3 million grant from the U.S. Department of Agriculture to study European foulbrood disease (EFD) in honey bees. The group is investigating the factors contributing to the high incidence of infection, and will then share their findings with local beekeepers and growers to improve mitigation efforts. Beekeepers in Oregon typically pollinate about five different crops annually. If the colonies are weakened by EFD, this results in less pollination, which is a concern for blueberry and almond growers.

Evolutionary biologist Michael Blouin was awarded $1.86M over five years ($371K per year) from the National Institutes of Health for his project entitled, “Genetic mechanisms of snail/schistosome compatibility.” Schistosomes are water-borne blood-flukes transmitted by snails, which infect over 250 million people in more than 70 countries and cause severe and chronic disability. A debilitating helminth parasitic disease of humans, vaccines are available for schistosomiasis. This project will identify new genes that make some snails naturally resistant to infection by schistosomes, revealing potential new ways to reduce parasite transmission at the snail stage.

Statistician Robert Trangucci received $164K from the University of Michigan for his project entitled, “Data driven transmission models to optimize influenza vaccination and pandemic mitigation strategies.” Selection bias is common in infectious disease datasets due to complex observational and biological processes, and bias can arise from covariate data which is missing due to analytical limitations. The research team is addressing the concern by extending existing models to accommodate risk and data gaps over time for application in vaccination and other novel datasets.

Chemist Dipankar Koley received $542K from the National Institutes of Health for his project entitled, “Microenvironmental characterization and manipulation to prevent secondary caries.” A common reason for dental replacement is a recurrence of caries around existing restorations caused by microbial activity. The project seeks development of new and innovative materials to bias this microbial environment toward improved dental health, and the researchers are investigating the use of cations of magnesium and zinc applied with specialized release platforms.

Collaborative research at the interface of robotics, computer vision and AI

Statistician Yanming Di received $249K from the U.S. Department of Agriculture for a project entitled, “DeepSeed: A computer-vision network for onsite, real-time seed analysis.” The Willamette Valley is considered the “grass seed capital of the world.” Seed testing, used for determining seed lot quality and establishing seed value, is a fundamental phase of the agricultural marketing system. With recent advances in robotics, computer vision, and AI, an opportunity presents itself for a new wave of innovations. This project utilizes AI and robotics to innovate devices and protocols for sampling grass seeds and a computer vision system for automated seed analysis. The investigators consist of experts in seed services, computer vision, statistics, and mechanical engineering.

Climate science and related solutions

Materials scientist Kyriakos Stylianou received $689K from Saudi Aramco for a project entitled “New Generation of CO2 Capture Adsorbents: Synthesis, Performance under Humid Conditions, and Scaleup.” In this project, the Stylianou group aims to discover novel adsorbents for the selective capture of CO2 from diluted sources. Successful materials will undergo scaling up and evaluation for their efficacy in removing CO2 from air.

Marine ecologist Bruce Menge received $200K from the National Science Foundation for his project entitled, “RAPID: A subtle epidemic: unique mortality of Mytilus californianus on the Oregon coast.”

The research team is investigating the major changes occurring in the Pacific Northwest marine ecosystems, with evidence these communities exhibit low resilience to climate change. For example, sessile invertebrates (mussels, barnacles, etc) become more abundant while seaweed species (kelp, etc) decline.

Evolutionary biologist Kathryn Everson received two awards for $276K from the University of Kentucky Research Foundation for a project entitled, “The role of hybridization in generating biodiversity: Insights from genomics of Madagascar’s true lemurs (Eulemur).” This project is funded by the NSF to understand how new species form in the context of complex gene flow and to expose the genomic signatures of evolutionary processes. The researchers will characterize patterns of gene flow, selection, and genome architecture for a species of lemur to gain a genomic perspective on the evolution of species boundaries. In addition, the team will construct a hybridization model using data on geographic range, diet, and social behavior for this lemur.

Clean energy and related solutions

Aerosol chemist Alison Bain received $284K from McGill University for her project entitled, “Single particle measurements.” This research aims to understand the optical properties of stratospheric aerosols. Using single particle experiments under environmentally relevant temperatures and humidities, the team will extend a wavelength-dependent refractive index model to include these conditions. They are also looking at how atmospheric aging impacts the optical properties of these materials.

Chemist Wei Kong received $110K from the American Chemical Society for her project entitled, “Superfluid helium droplets as microreactors for studies of photochemistry of fossil fuel hydrocarbons: polycyclic aromatic hydrocarbons and the corresponding endoperoxides.” The project will use superfluid helium droplets as microreactors to investigate the kinetics of the photooxidation process of a major component of petroleum (polycyclic aromatic hydrocarbons, PAH). Using several analytical techniques, the team will test the hypothesis that supercooling the helium droplets will stabilize an excited state of the oxygen molecule and prevent further reactions.

Collaborative partnerships to fuel a thriving world

Biochemist Ryan Mehl received $234K from the NobleReach Foundation in partnership with the National Science Foundation. The project “Ideal eukaryotic tetrazine ligations for imaging protein dynamics in live cells” was selected as one of the first set of 11 national pilot projects to receive $234K from the NobleReach Foundation.The partnership seeks to identify and accelerate the translation of NSF-funded research into biotechnologies and bio-inspired designs with commercial and societal impacts. This pilot will help inform future translational funding opportunities along with enabling Professor Mehl and the other selected principal investigators to accelerate bringing their research to the market and society.

Biochemist Patrick Reardon received $500K from the National Science Foundation (NSF) Research Instrumentation Program for his project entitled, “MRI: Acquisition of Helium Recovery Equipment: An integrated system for helium capture and recovery for the OSU NMR facility.” This award supports the acquisition and installation of an integrated system for helium capture and recovery for the nuclear magnetic resonance (NMR) facility. Helium is in high demand and is used for a wide variety of industrial and research applications, and it is a non-renewable resource which highlights the need for laboratories to capture and recycle this important gas. The NMR lab is supported by funding from the National Institutes of Health, NSF, M.J. Murdock Charitable Trust, and OSU, and it is a core facility and cornerstone for groundbreaking research in interdisciplinary science and engineering, chemistry, biochemistry, and biophysics at OSU, throughout the Pacific Northwest, and beyond. The facility continually strives to enhance its state-of-the-art instrumentation for the highest levels of analytical performance.

"When I started to take more physics classes, I thought, 'Wow, this physics stuff is really cool,' and it just clicked,” Takach said. One thing led to another, his passion grew and he pivoted entirely.

"Not to say that math isn’t beautiful, but I think that applying math to something real is what is most important."

Takach is graduating this summer with a double major in physics and mathematics. "The coolest thing about the math department is how flexible it is. And in the physics department, everyone's really friendly and there's lots of interaction between students," he said.

In the fall, Takach is moving forward with a Ph.D. program at University of California, Berkeley, focusing on particle physics and phenomenology. This involves looking for things that can be observed and may not be obvious experimentally. Instead of testing a hypothesis, phenomenologists choose a mathematical theory and try to “tease out” observations. After they decide what the observable effects are, they tell experimentalists to go looking for them in real life applications.

By chance, physics meets education technology

Takach found a lot of faculty support that allowed him to make an impact early on in his academic career. In his first year, one of his main advisors, Associate Department Head David Craig became his go-to resource for knowledge.

“I did the naive freshman thing and went to Craig because he was one of the resident theoretical physicists here. He directed me to a bunch of stuff to study in my free time and what books to read. He also motivated me to start learning on my own, and helped me learn how to attack those high-level concepts early without waiting to be in a class.”

Takach’s journey didn’t stop there. Last summer, he landed an internship at University of California, Davis, where he gained experience working with computational physics and quantum field theories in the realm of particle physics.

At Oregon State, he worked on campus as a peer advisor for the Science Success Center and as a learning assistant for the Techniques of Theoretical Mechanics course in the physics department.

His passion blossomed when he learned how to utilize the power of Python, a computer programming language, to create educational videos about high-level physics concepts and make the content more accessible to students who haven’t learned it.

“Getting an early start and giving kids the opportunities to learn more as early as they can is so important. It becomes second-nature if they start early enough,” he said.

Inspired by YouTuber 3Blue1Brown, who made animated mathematics content, Takach created his own video to help more students have access to an engaging, easier-to-grasp learning experience. His goal was to teach about an advanced mathematics topic: curl.

In vector mathematics, curl is a concept that involves measuring the rotational or swirling behavior of a vector field. A vector is a direction with a specified measurement, such as how fast a golf ball moves forward when hit with a golf club. Imagine a bunch of arrows pointing in the direction that the ball is moving – the longer the arrows, the stronger the force in that direction.

“There are tons of people online that make these kinds of videos. Making this content accessible to younger people is essential because the amount of science you need to know in order to advance in a field is very daunting,” Takach said.

He sent his video to Physics Professor Emeritus Corinne Manogue, the leader behind the Paradigms in Physics project funded by the National Science Foundation. This physics education project led to the creation of 19 new physics courses and focused on shifting the curricula from traditional lectures to active engagement for students at Oregon State.

She hired Takach to make more educational videos that were aligned with the physics curriculum, including quantum mechanics. The videos were intended to improve the learning experience for future physics students.

“The most concrete thing that I want to have an impact on is teaching. I love sharing the experience of learning something for the first time. It happens so frequently – it's the weirdest experience and when you share that with someone, It’s motivating, fulfilling and fun,” he said.

Physics Associate Professor Elizabeth Gire also had a positive influence on his academic career. After she taught one of his first upper-division physics courses, he left feeling inspired. "She really, really cares about the students and how much everyone's learning. I think that rubbed off on me. The way she goes about teaching and encouraging people to work together is definitely something to look up to and had a big impression on me.”

Looking back, one of Takach’s favorite memories at Oregon State is living with his friends for three years. "Two of my best friends from high school are still my roommates now. They’ve been a great support system.”

During his free time, Joey loves to dive into music and plays several instruments, including guitar, bass, viola and violin. When the sun comes out, he enjoys hiking, backpacking and traveling.

After completing his Ph.D. in California, Takach dreams of becoming a physics professor. “Learning and teaching for as long as possible is the most ideal for me. I need the connection to what is actually real. Not to say that math isn’t beautiful, but I think that applying math to something real is what is most important.”

His road to graduation started with his father.

"I was very good at math when I was a kid, and my dad tried to hone in on that," he said. "He always told me how when he learned math, he memorized formulas and that got him through math even when he didn't always understand it."

Even if math didn’t rise to the level of a passion quite yet in Holzschuh's young life, he spent a lot of time crunching numbers. "I would always spend hours learning to understand the math I was doing," he said.

All that time paid off when he arrived at Cleveland High School. "I quickly picked up on math because I had such a strong foundation that I could easily build on," he said.

"That led to being very good at math and very good at physics," he added. "I didn't pursue physics because there are just a couple of concepts I really didn't understand, like when I started learning about Feynman diagrams."

Feynman diagrams are pictorial representations of mathematical expressions describing the behavior and interaction of subatomic particles.

Physicist Richard Feynman used wavy lines to represent photons. In physics as well as mathematics, a wave is a propagating dynamic disturbance of one or more quantities. "Waves are pretty weird," Holzschuh said. "Waves always tripped me up, so I decided to focus on math."

Oregon State was a fairly straight-forward choice for college, he said. Other colleges and universities in Oregon don't offer as many classes in statistics, and Holzschuh also wanted to stay close to home.

"I came to Oregon State mostly because I'm from Portland, and it was pretty easy," he said. "I wasn't moving too far, and I still had a little bit of freedom. I also knew a lot of people here, so it would be an easy transition into college."

Once in Corvallis, Holzschuh said he was impressed with the university's world-class faculty, and his love of math flourished.

"I love the theory behind math," he said. "It's super interesting to me how you predict outcomes."

He added he also loves how math is so unambiguous.

"I like how math has one answer," he said. "When you're doing calculus, there's one answer. Now that I'm in more proof-based analysis level math, I like how you go from Point A to Point B, and there are different ways to go, but you're always going to get to Point B."

His other academic passion is not known for its lack of ambiguity.

"Math and science were my big subjects in high school, but I also had a small interest in philosophy," Holzschuh said. "I really do still love philosophy."

He just doesn't have a lot of time to hang out with Plato, Descartes and their 21st-century counterparts as a mathematics major.

"Because I spend most of my time studying math, I don't have the reading comprehension level to truly understand a lot of the current philosophy papers," he said. "They're just so heavy and dense."

Still, he has friends ready to help. "One of my best friends is a philosophy major in Belgium, and he will talk to me about philosophy for hours," he said. "I really love it."

"Being able to go on the scheduling website and just take a bunch of math classes, it makes me pretty happy."

Being a math major has not kept him socially isolated, he added.

"I've met so many different people from so many different majors," Holzschuh said. "One of my best friends is a mechanical engineer. My two roommates are botany and English majors."

Students recognized for expertise in certain subjects in high school are often humbled when they arrive at college and are no longer the big fish in a small pond.

Even if he was no longer one of a handful of math stars, Holzschuh said he found coming to the mathematics community at Oregon State exhilarating.

"I actually liked it," he said. "For one, college allowed me take the classes I wanted to take. I went from high school, where I took one math class a year and seven other random classes, to where I'm taking 20 hours of math and statistics this semester."

He added, "Being able to go on the scheduling website and just take a bunch of math classes, it makes me pretty happy."

Undergraduate students usually spend much of their freshman and sophomore years taking required lower-division classes, regardless of their majors.

"Once you get past your second year in mathematics, it really opens up," Holzschuh said. "I came in a year ahead on my math track, so once I got to my second year, I could take linear algebra, and once you've taken that, basically everything opens up. You can pretty much take any math class in any field."

He has taken such general elective classes as differential equations, complex variables ("which is really interesting"), math models and math biology.

"I never thought I would take anything related to biology because I hated biology in high school, but that was an interesting class," Holzschuh said.

After graduation, he intends to move from Corvallis in August to start graduate school at Boston University.

"I selected Boston University because it's on the East Coast," he said. "I really want to go there, especially because of math and finance. The East Coast is a great place to be for that. Also, Boston seems beautiful, and it's close to New York."

After grad school, Holzschuh said he hopes to remain on the East Coast and pursue his love of numbers as a quantitative analyst -- designing, developing and implementing algorithms and mathematical or statistical models to solve complex financial problems.

"It's a very challenging career path, and I really like being challenged," he said.

A mathematical odyssey in energy and climate

Peszyńska specializes in modeling, analysis, and numerical analysis of models, a discipline that seeks to describe real-world systems mathematically, so they can be simulated, analyzed predicted and — when there are problems — solved.

With expertise that spans disciplines, Peszynska primarily works to mathematically solve problems related to environment and, recently, climate change. Her modeling of mass and energy flow and transport includes porous media phenomena in aquifers, oil and gas reserves, carbon sequestration, solar cells and the effect of permafrost warming. Perhaps most notable is her work on phase transitions in methane hydrate transfer and evolution, as well as in using computational mathematics to study complex pore-scale environments. This work aims to understand and predict the presence and behavior of fluids in nature to mitigate potential disasters, like hazardous explosions or methane emissions contributing to global warming and addressing challenges in climate science and geophysics.

In her recent NSF-supported work on studying permafrost changes, Peszyńska seeks to predict and mitigate potential large-scale events such as building collapses and coastal erosion, highlighting the urgency for more modeling in this area.

Her research team employs computers to approximate solutions, striving for accuracy even when the true solution is unknown, she explained. Ultimately, they contemplate how computational algorithms can approximate truth without certainty, exploring the mysteries of mathematics.

"There's so much about the methods themselves that intrigue us in this mystery," she said. "How do you achieve that? How can you anticipate whether your computational algorithm will yield a prediction close enough to the true solution, regardless of what that true solution might be, without actually having knowledge of it?"

Peszyńska will explore this and other questions in her public lecture. She will also “delve into how her research team explores multi-scale multi-physics systems using complex computational mathematics, inspired by real-life applications. She will discuss their investigation of porous media at nano-, pore-, lab-, and field scales, predicting their responses to environmental changes. She will also emphasize the importance of fostering interdisciplinary collaborations within Oregon State University and with external partners to encourage students to embrace complexity over simplicity.”

From Warsaw to worldwide impact: A wholehearted journey

Born and raised in Warsaw, Poland, Peszynska discovered her passion for mathematics at a young age. Encouraged by her family, she cultivated that passion alongside her love for the natural world, leading her to study mathematics in the context of physical phenomena and ultimately specialize in mathematical modeling and computational solution of flows through porous media and their geological applications.

She earned a master’s degree in applied mathematics from the Warsaw University of Technology and a Ph.D. in mathematics from the University of Augsburg in Germany. She also holds a habilitation degree from the Warsaw University of Technology.

Her interest in real-life applications is driven, in part, by a personal passion for the natural environment and outdoor activities. And she commits fully to her pursuits, whether tackling complex equations, building interdisciplinary teams, or enjoying leisure activities like skiing and sailing. Embracing her mantra to "Make your own kind of music," she consistently tries to choose the complex and challenging path over the simple and easy.

Reflecting on the most meaningful milestones and accomplishments that led to this recognition, Peszynska shared that it's not about one single thing but rather a tapestry of efforts woven from countless interesting problems and diverse potential directions.

“At every fork in the road, we are choosing a path and sometimes we succeed in making progress,” she said. “At times, the most cited papers are the easiest for us, and sometimes those least noticed are the hardest but might make an impact much later. This may be scary when looking ahead, but it gets easier over time.”

She likens her role as a mathematician to that of a translator, bridging gaps between disciplines and applying mathematical rigor. Collaborating with colleagues from within mathematics and across other fields has empowered her to tackle real-world modeling projects with significant practical implications, even in the absence of a clear existing mathematical framework for analysis. From exploring multi-scale modeling techniques to navigating complex algorithms, these partnerships have broadened her perspective and fueled innovation.

As a mentor, she encourages students to discover their passions and gently nudges them to work diligently towards their goals, knowing they might change their minds along the way. But, she said, “There's no substitute for hard work. Sometimes, it's not just about assignments or tasks; it's about doing repetitive steps and finding the discipline to keep going. One of my past mentors said, ‘All you can do is work.’ And that's true. It means showing up every day, putting in your hours, and eventually, things will click. In turn, mentoring isn't easy. You offer advice, but ultimately, it's up to them to decide what works best for them. It's not unique—I don't have all the answers. Live and let live, I suppose—that's another principle I try to uphold.”

One of her former students, Scott Clark ('08), listed in Forbes Magazine’s 30 under 30, shared, “Dr. Peszyńska’s guidance led me down the interdisciplinary path that would become the foundation of my later graduate and professional work. ... She had a direct, positive impact on my career trajectory, and I would not be where I am today without her.”

At that, she humbly replied, “We have a lot of brilliant undergraduate students, and they just need an opportunity to fly. And so we should be accommodating them, I think. Yeah, let them fly."

She has also found leading the community in various professional circumstances gratifying—“building one connection at a time and not letting go.” Peszyńska has served as a program director for computational mathematics for the NSF and in multiple roles for the Society for Industrial and Applied Mathematics. Additionally, she organizes conferences, serves on editorial boards, and participates in review panels for prestigious institutions.

Challenges and rewards: Bridging disciplinary divides

Peszynska’s success in bridging complex mathematics and diverse real world disciplines has much to do with her independent and joyful spirit.

She describes her atypical view of computational and applied math as an "attitude," rather than a discipline. “My work leans closer to art in its abstract form, or closer to science and engineering in its useful side. This dichotomy is not always understood or appreciated, and it feels funny and sometimes tedious that we may have to prove ourselves over and over. Doesn't everyone want to have clean air, enough food, exciting and intellectually stimulating complex work and stability of life? Live and let live!

“But my strategy is to not try to win anyone over to interdisciplinary work but rather to enjoy the intellectual and emotional joy of learning the new language while appreciating the cultural differences. The reward is that you build the bridges rather than straddle the fence.”

To apply her discipline and contribute wholly to critical concerns is very hard work, and she competes mostly with herself, harnessing discipline if ever enthusiasm wanes. Just as she advises her students: Do the work.

“On the lighter side, most days I wake up happy in the morning to continue doing this work,” she said. “It's fun, more fun than video games because I can make my own with the simulations. So that's exactly what I hope for others, especially students, that they will find fun in it—potentially even more, making a difference, one step closer to a better world.”

Curious minds may explore Peszyńska’s website for its challenges and interactive learning. Exploring innovative solutions can feel akin to solving puzzles, but even more rewarding.

The lasting impact of her work that she will hold most dear is the enduring value of lifelong learning and the significance of interdisciplinary collaboration—with its potential to shape the future. And she truly hopes that students will experience and appreciate the intrinsic joy and real-world impact that computational and applied mathematics have to offer.

“I am thrilled to see Malgo Peszyńska get this well-deserved recognition,” said Eleanor Feingold, dean of the College of Science. “Her world-class work in mathematical and computational modeling, coupled with her dedication to interdisciplinary collaboration, are instrumental in shaping the future of environmental science.”

Along her journey, Peszyńska has had to choose between many forks in the road. With too many options to follow in one lifetime, she acknowledges the opportunities left behind for future lives.

What might she pursue in her next life? Well, she might need two (or more). “Right now, my count goes into the upper teens.”
