Meet Scott Clark, an OSU science alum who built a $30M AI startup

By Tom Henderson

Scott Clark (08) wants artificial intelligence to be powerful — and trustworthy.

The College of Science alumnus is a mathematician, physicist and machine learning expert who has spent the last decade working at the cutting edge of optimization and artificial intelligence. He’s also a repeat founder. In 2014, he launched SigOpt, a startup that helped some of the world’s largest companies fine-tune their machine learning models. He sold it to Intel in 2020.

Now, he’s doing it again.

Clark’s latest venture, Distributional Inc., is focused on a fast-growing challenge in today’s AI landscape: reliability. The company helps organizations test, calibrate and monitor AI systems — ensuring they behave as expected and can be trusted in real-world use. It’s already raised $30 million and grown to a team of 30.

"Faster cars are better, but not everyone wants an F1 car," Clark said. "That would be ridiculous, People want Honda Civics. People want cars they can trust. This seemed like another hard mathematical problem we could solve."

Focusing on reliability is important during the latest surge in AI technology, he said. "If reliability and confidence are ever going to matter, it's right now."

How the College of Science prepared him to change the landscape of AI

When Clark arrived as a freshman at Oregon State in 2008, he met Rubin Landau, who ran the (since discontinued) computational physics program at the time. Clark became especially enthralled with Landau's work after checking out one of his books from OSU's Valley Library.

"It was everything that I loved, all put together," Clark said. "It was physics with math on computers. It was like, 'Here's how you teach a computer physics.'"

He convinced his advisor to let him take a 400-level class as a freshman. Although he started out as a math and computer science double major, he switched to a triple major in math, physics and computational physics halfway through his freshman year.

"One of the things I loved about Oregon State was that they let me explore as much as possible."

Oregon State has one of the best numerical analysis departments in the world with legendary professors such as Malgorzata Peszynska and Bob Higdon, he added.

"One of the things I loved about Oregon State was that they let me explore as much as possible," Clark said. "They never told me I wasn't allowed to take a class because I didn't have the prerequisite, or it was a 600-level class, and I was only a sophomore. They always let me try it, to jump into the deep end and see if I could swim."

Clark began expanding his work, pursuing summer Research Experiences for Undergraduates (REUs) in biophysics at the University of California at Davis. He also worked at the Max Planck Institute in Germany, doing computational quantum mechanics work.

He and Malgorzata Peszynska spent a summer working on fluid dynamics problems.

"What I really loved was all this interdisciplinary work of how you fit these fields together and using computational simulations to push that forward," Clark said.

After graduating from Oregon State in 2012, he pursued graduate school at Cornell University in its applied mathematics department. "I could work on all these problems that would otherwise fall through the cracks," he said.

Clark soon received a fellowship from the U.S. Department of Energy, allowing him to work in computational science at various national laboratories, including Los Alamos and Lawrence Berkeley. The latter focuses on scientific discovery and solving large-scale problems in energy, health and the environment.

"A lot of these problems end up looking similar," Clark said. "They end up looking like difficult optimization problems where you build some big, complex machine, system or algorithm, and you want to make it work as well as possible."

Figuring out how to use computers to solve extremely hard optimization problems became his next passion, Companies often spent exorbitant amounts of money grappling to increase optimization. Clark saw an opportunity. "In as few attempts as possible, you want to get to the best possible answer," he said.

Toward the end of graduate school, he faced a choice -- heading to academia or industry. He decided it would be more interesting and fast-paced to at least try industry first.

Scott Clark shakes that hand of his Ph.D. advisor, Peter Frazier, after getting his hood on graduation day at Cornell University in 2012.

An internship with Bloomberg in New York City working in finances helped finalize his decision. Clark recalled the thrill of working at a fast pace with highly intelligent people.

"Everyone had something to optimize."

He took the private-sector skills he acquired in New York City and began working for Yelp. The company needed help building a targeting system as it ventured into advertising. "This was like a really fun, hard math problem," Clark recalled. "There was enough scale to make it really interesting, but it was early enough that it was very greenfield, so I wasn't trying to make something slightly better. We were starting from scratch, basically."

It struck him other companies could benefit from what he was doing for Yelp. He created MOE -- the Metric Optimization Engine -- and presented it to companies like Google, Facebook and OpenAI.

"Everyone had something to optimize," Clark said. "I learned this was an extremely pervasive problem."

In 2014, Clark founded SigOpt to market the software he developed to use machine learning and complex algorithms to optimize user experiments for websites and applications. He improved data collection for everyone from federal intelligence agencies to hedge funds and big banks. Traveling the world, he built a team of 30 people and raised $17 million in seven years.

After selling the company to Intel in 2020, he became Intel's vice president of AI and High Performance Computing Software teams within the Supercomputing Group -- helping people build even bigger and better computers. However, after two years, a thought kept nagging him. Customers didn't necessarily want the best result. They wanted the most reliable result.

Thus was born Distributional Inc.

The company creates reliable AI by creating better testing, automating test creations and calibration -- allowing organizations to reduce risk by standardizing testing throughout the life of all their AI technology.

"It's all about how to test them and make sure they're behaving as we wish," Clark said.

A lifetime love of computers

Clark has been working with computers since he was 10 years old in the early 1990s, and his father brought discarded office computers home.

"I tinkered around with QBasic and stuff like that,” he said. “I was always interested in making machines do things that I found interesting, even if it was just printing my name over and over on one of those old terminals."

He built computers for people while he attended Central Catholic High School in Southeast Portland -- customizing early Dell and Gateway computers. "I was willing to value my time at $10 per hour so I could undercut someone who was just updating HTML."

Clark built several dozen computers for local businesses and friends and designed websites. Then his interests took a cosmic turn.

"I became interested in more than how computers work and became interested in how the world and the universe work," he said.

He was particularly interested in physics and began reading Richard Feynman's lectures on theoretical physics. This led to Clark taking advanced placement courses as well as classes at Portland Community College.

"I wanted to understand physics, because that's the way the world works, and I wanted to understand math because that's the language of physics," Clark said.

"I was never told anything was impossible, so I never stopped."

However, his fascination with computers remained. "I was always interested in how you can make computers much faster, how you can run simulations and things like that," he said. "I was enthralled by these very beautiful simulations of fluid dynamics and partial differential equations."

Clark, now 38, said everyone will be touched by AI -- even the engineers who create and service the machines

"I see a lot of companies now not hiring engineers just because it's so efficient to have a system that writes a lot of stuff too," he said. "Engineers are definitely going to be touched by AI. The pace of change is insane. Even working in the field, staying on top of AI is hard. It’s definitely exponential."

Clark's parents weren't engineers or scientists, but while they knew nothing about creating artificial intelligence, he said they knew a lot about nurturing it naturally.

"I'm definitely here as a product of the encouragement of my parents," said Clark, who was born in Salem and raised in Tigard.

"We were exploring together," he said. "I remember my parents were very quickly unable to help me with my math homework anymore, but they were always very encouraging. They'd let me take over the entire dining room table."

It was that kind of encouragement that made him the tech entrepreneur he is today, Clark said. It was the support he also found at Oregon State.

"I was never told anything was impossible, so I never stopped," he said.

‘Impossibility Results in Mathematics’: Lonseth Lecture 2025

By Arie Henry

“You can't square the circle!”

“The square root of 2 can't be written as a fraction!”

“The integral of e^{-x^2} can't be written in closed form!”

“Bitcoin is unbreakable!”

Most of mathematics is about finding solutions to problems or approximating them well. But there is an important collection of results that show certain tasks are mathematically impossible. At this year’s Lonseth Lecture, mathematician Matthew Foreman explains what that means, and the varying notions of impossibility:

40th Annual Lonseth Lecture

Date: Thursday, May 1, 2025
Time: Department awards at 3:30 p.m.; lecture at 4 p.m.; reception to follow
Location: LaSells Stewart Center, Construction and Engineering Hall

We'll begin by honoring student and faculty achievements at our annual awards ceremony from 3:30 to 4 p.m. Then we'll settle in for the lecture, given by Matthew Foreman, from 4 to 5 p.m. A public reception will follow immediately after.

About the speaker: Foreman's mathematics career began very young, receiving his bachelor's degree at the age of 18. He earned his Ph.D. in 1980 at University of California, Berkeley under the direction of Robert M. Solovay. In 1994, he answered a 60-year-old problem about the Banach-Tarski paradox by showing that there is a paradoxical decomposition of the sphere using pieces with the property of Baire. Today, he is a set theorist at University of California, Irvine and has made contributions in widely varying areas of set theory, including descriptive set theory, forcing and infinitary combinatorics.


Established in 1985, the Lonseth Lecture series pays tribute to the legacy of Arvid T. Lonseth, a respected figure in the Mathematics Department at Oregon State University. Explore more about Arvid Lonseth and the lecture series to appreciate its significance within academia.

Transforming river health, ecology, seaweed, and pest control: Revolutionary SciRIS research

By Hannah Ashton

The College of Science Research and Innovation Seed (SciRIS) Program continues to drive groundbreaking research by fostering collaboration and innovation. Founded in 2018, SciRIS funds interdisciplinary research projects that aim to create meaningful societal impact. This year, Stage 2 awardees are working to revolutionize our understanding of river health, ecological communities, sustainable seaweed cultivation and insecticide resistance.

There are two tracks through the program: SciRIS team awards (Stages 1-3) and the SciRIS individual investigator award (SciRIS-ii). SciRIS Stages 1-3 funds teams in three stages to support training, research, and capacity-building, accelerating work toward external funding opportunities. SciRIS-ii funds individual faculty to establish research relationships with external partners, enabling them to demonstrate the feasibility of their ideas and quickening the pace of scientific discovery.

Four teams received SciRIS Stage 2 awards.

Bioinformatics for integrated river health

Biologist David Lytle’s project focuses on understanding the complex interactions between multiple biotic components, including food base, disease landscape and microbiome in the lower Colorado River, including the Grand Canyon. Lytle will be working with three Oregon State colleagues, along with collaborators at the United States Geological Service and the National Parks Service. The project aims to develop diagnostic tools that can identify fish parasites and diseases at a molecular level and provide preliminary data on how these parasite, microbial and invertebrate communities change over time.

Ripening Oregon blackberries, one of the crops at risk from Spotted wing drosophila

Spotted wing drosophila are an invasive pest that attack several crops essential to Oregon farmers, including ripening blueberries, blackberries, apples and stone fruit. Fruit fly populations evolve rapidly and the Patel and Vrailas-Mortimer group seek to understand the risks of resistance evolution before they adapt to local pesticides.

Insecticide resistance in spotted-winged drosophila

Geneticist Alysia Vrailas-Mortimer's project addresses the significant agricultural threat posed by spotted-winged drosophila (SWD), an invasive pest species. The research aims to advance understanding of the genetic basis and evolution of insecticide resistance in these pest populations through experimental work, genetic techniques and mechanistic mathematical modeling. The project involves collaboration with experts from UC Davis and focuses on developing sustainable control methods. Directly connected to the needs of the Oregon agricultural community, this project is a prime example of OSU’s strong community engagement initiatives as a land grant institution. By learning more about the mechanisms of insecticide resistance in spotted-winged drosophila, growers will be better able to plan and prioritize their insecticide applications to mitigate resistance.

Mathematician Axel Saenz Rodriguez earns competitive Simons Foundation Pivot Fellowship

By Hannah Ashton

Axel Saenz Rodriguez, an assistant professor in the Department of Mathematics, has been awarded the prestigious Simons Foundation Pivot Fellowship for his groundbreaking work at the intersection of probability theory and mathematical physics.

The Simon Foundation Pivot Fellowship is a highly competitive award that supports early-career researchers seeking to pivot their research into new, impactful scientific areas. The fellowship provides recipients with resources and mentorship from leading experts to explore innovative directions in their research.

“Only eight Pivot Fellowships were given in all of science, math, and engineering this year. Axel’s achievement in securing this fellowship speaks volumes about his interdisciplinary approach to research and the impact of his work,” said Department of Mathematics Head Jon Kujawa.

Saenz Rodriguez will use the fellowship to bridge theoretical models in probability and mathematical physics with experimental work in two-dimensional quantum magnetic materials, a field with vast potential for next-generation technologies, such as clean energy and computational advancements.

As part of the fellowship, he will be mentored by Eric Corwin and Oksana Ostroverkhova, faculty members at the University of Oregon and Oregon State University, respectively. The pair will help Saenz Rodriguez in scientific practices for high-performing numerical computational and experimental physics.

Saenz Rodriguez joined the College of Science in 2021, along with his spouse Swati Patel. His work involves creating exact formulas to analyze various processes in space and time using different areas of mathematics, like algebra, geometry, and combinatorics. His research mainly looks at the Kardar-Parisi-Zhang (KPZ) universality class, which describes certain random behaviors in one-dimensional systems with complex interactions. Saenz Rodriguez aims to develop a clearer understanding and practical uses of the KPZ class.

In 2023, he helped co-organize the Math For All satellite conference, hosting about 40 people in Corvallis for free. The aim is to foster inclusivity in mathematics. The conference welcomed people from Linn-Benton Community College, Chemeketa Community College, Portland State University, University of Portland and Oregon State.

Prior to Oregon State, he was a postdoctoral researcher at the University of Warwick, Tulane University and the University of Virginia where he was the Mary Ann Pitts Postdoctoral Fellow in the Department of Mathematics. He earned his Ph.D. in mathematics from UC Davis and his bachelor’s in applied mathematics from Columbia University.

Advances in mathematics education net Elise Lockwood the presidential award

Elise Lockwood, a professor in the Department of Mathematics in the College of Science, has been honored with the Presidential Early Career Award for Scientists and Engineers (PECASE), the highest honor bestowed by the U.S. government to outstanding early-career scientists and engineers.

Nearly 400 scientists and engineers received the PECASE from President Biden in January 2025. This award recognizes Lockwood’s innovative research in mathematics education and her potential to advance the field.

Lockwood’s research focuses on how college students learn mathematics, especially combinatorics, the branch of mathematics that focuses on counting objects and identifying patterns within defined parameters. Her work sheds light on how students approach and solve complex counting problems, offering insights that significantly enhance mathematics education.

“I’ve dedicated significant time and effort to carve out this space of trying to improve students’ combinatorial reasoning, and it means a lot that it’s being appreciated. I’m also very fortunate to have had wonderful colleagues and collaborators, as well as the support of the NSF, Oregon State and my students,” Lockwood said. “It’s an honor, and I feel very fortunate and blessed.”

She switched to a mathematics major late in her academic career, initially unaware that studying mathematics education was even an option. Her original plan was to attend graduate school and become a high school mathematics teacher. However, one class changed her trajectory.

“I took a combinatorics class and was fascinated by these problems that were easy to state but kind of difficult to solve. I had a bad experience with them as an undergrad, and I realized I could study ways to improve how these problems are taught and understood by students. That became my passion,” she said.

Unlike solving a calculus equation, which often seems like following a well-lit trail with a pre-existing path to reach an answer, combinatorics problems can feel like they are all unique. Lockwood has discovered that students want more structure, and she has accomplished this by helping them focus on the nature of what they are trying to count instead of focusing on applying a formula.

“Oregon State values STEM education and STEM education research.”

By focusing on how students conceptualize and reason through combinatorial problems, she has redefined traditional approaches to teaching this foundational area of mathematics. Her work integrates deep theoretical insights with practical applications, enabling educators to move beyond rote memorization and formulaic problem-solving to foster genuine mathematical understanding.

Her career path and numerous awards showcase her dedication to mathematics education. She joined Oregon State in 2013, partly because she was excited that “Oregon State values STEM education and STEM education research.”

She is currently a co-editor in chief of the International Journal of Research in Undergraduate Mathematics Education. She is also an academic staff member of the Center for Computing in Science Education at the University of Oslo, Norway.

From 2021 to 2024, Lockwood served as a program officer at the National Science Foundation in the Division of Undergraduate Education, where she was involved in overseeing and managing NSF-funded projects aimed at improving undergraduate STEM education. This role further informed her research on effective teaching practices, and she influenced broader policies and practices in STEM education.

In 2019, she was part of a $141K, one-year grant from Google to enhance and increase integration between computer science education and mathematics teacher education curriculum. The project was aimed at better equipping teachers to teach computational concepts and practices in Oregon high schools.

In 2017, Lockwood received a $800K five-year NSF CAREER Award to study how computational tools and activities, specifically introductory Python programming, can aid students in solving complex combinatorial problems. Her published research on using basic Python programming for undergraduate combinatorics problem solving paves the way for novel and creative methods of using computing to support students’ mathematical reasoning.

In addition to her PECASE award, Lockwood has received the John and Annie Selden Prize for Research in Undergraduate Mathematics Education, the Promising Scholar Award from Oregon State and a Fulbright award. Her work has already influenced the field of mathematics teaching and curriculum development, enabling students to gain a deeper, more intuitive grasp of combinatorial concepts — skills that are critical for careers in science, technology, engineering and mathematics.
