What is an actuary?

At its core, actuarial science uses mathematics, statistics and financial theory to manage risk and inform decision-making. While the work is rooted in numbers, it is ultimately about helping institutions understand what could happen in the future — and how to plan for it.

The profession is structured around four main practice areas: health, life, property and casualty, and pensions. Each track focuses on a different kind of risk and requires specialized knowledge of industries, regulations and financial systems.

Health actuaries, like Baird, work with hospitals, insurance companies and government programs to analyze medical costs, design insurance pricing and evaluate how healthcare services are funded and delivered.

“We’re trying to make sure that their prices are fair, and that they are financially stable,” she said.

Baird started at Milliman as an actuarial analyst, supporting a software product designed to predict individual health care costs using past claims data. She trained predictive models, validated them and answered client questions.

Over time, her role expanded. Baird discovered she excelled in consulting, working directly with clients to solve unique problems. She now leads research and development for the software product and holds a senior-level position on the consulting side. Her work ranges from pricing Medicare plans to helping hospitals understand payment models to evaluating how successful medical interventions are at improving patient outcomes.

“My days are never boring," she said. “Clients bring us hard problems and we get to design studies, build models and really dig into whether something is working.”

No two assignments look the same, she said, because no two clients are trying to solve identical problems. That variability is part of what keeps the work engaging: each project requires adapting models, interpreting data in context and explaining results to non-technical audiences.

While insurance can be a complex and sometimes frustrating system for consumers, Baird emphasizes the broader mission behind the work.

“It can be tricky, but it can also save lives,” she said. “We aren’t just there to help insurance companies make more money. We’re there to help them serve the people that need health care.”

In January 2026, Baird joined the Actuarial Standards Board, which sets standards that actuaries in the U.S. must follow in their work. It also oversees updates to those standards through volunteer expert task forces and public comment, helping ensure consistency and professionalism across the field.

“It's been a great experience because they’re all people who are really passionate and excited. We spend a lot of time in passionate discussions and debates, making sure we think through all the implications of the guidance that we’re creating. Am I setting the bar too high for actuaries? Or am I not setting it high enough?”

Baird’s take on how to become an actuary

Baird grew up in Central Point, Oregon, and was interested in pursuing a degree in education, but a high school calculus class shifted her trajectory.

“I really enjoyed the problem-solving aspect of it,” she said. “It felt like the first time you moved beyond mechanics and got to how we use math to solve problems.”

That realization led her to pursue mathematics at Oregon State, where she eventually completed her undergraduate degree, master’s degree in mathematics and a dual Ph.D. in mathematics and statistics.

Her interest in actuarial science didn’t take hold until graduate school. After taking her first probability course, she began to see new possibilities, deciding to take her first actuarial exam while she was still in school.

Becoming an actuary requires a series of rigorous professional exams that unfold over several years. Candidates complete seven exams and a series of modules and other courses to reach Associate status, with several additional exams and modules needed to be fully credentialed as a Fellow. Most candidates study while working full-time, turning the exam process into a parallel track of education and career experience.

Always being open to learning benefited Baird when she started at Milliman. New terminology, processes and expectations felt overwhelming. Although she credits her graduate training for helping her develop critical skills like note-taking and technical writing, it took her time to adjust.

“For the first six to eight months, I felt completely out of my element,” she said.

Doubting yourself in a new role is a normal experience, Baird said, but those feelings won’t last forever. Over time, that uncertainty gave way to confidence and she took on leadership roles.

For students interested in actuarial careers, Baird recommends gaining early exposure to the field by taking exams and pursuing internships. Equally important are soft skills.

“We’re a very collaborative group,” she said. “Making sure that you can show that you have successfully worked as part of a team or led a team is helpful.”

Actuarial work goes beyond spreadsheets and equations; it’s about using math to guide decisions that affect people’s lives. From shaping how healthcare is delivered to ensuring organizations can meet their financial commitments, that work carries real consequences. For Baird, it’s a job that lets her use mathematical skills in ways that have real-world impact.

Beyond her administrative role, Timshel actively fosters a sense of community within the department. She organizes fundraisers and charity events and regularly attends student events to show her support.

Distinguished Service Award

Elaine Cozzi, assistant head and associate professor in the Department of Mathematics, received the Distinguished Service Award for her impactful service to her department, the College and the broader mathematics community.

Cozzi served as interim associate dean of academic and student affairs for the College in Spring of 2024, managing various projects, including the university’s revision of its undergraduate advising system, assessing teaching resources and addressing countless student issues. She was overwhelmingly generous with her time in responding to the many challenges and the needs of her colleagues.

Before and after serving as associate dean, Cozzi served as assistant department head for mathematics, responsible for scheduling upper-level courses and ensuring adequate staffing for the Department’s teaching mission. This affects the hiring of instructors, graduate students, and undergraduate graders.

Jon Kujawa, Department of Mathematics head and Cozzi’s nominator, noted, “It is hard to overestimate the impact of Elaine’s planning on the smooth operation of the teaching side of the department. And she readily pivots when unexpected events disrupt the plans.” Additionally, Elaine led the assessment of the Mathematics undergraduate program for several years, playing a crucial role in student success, he shared.

Cozzi also contributes significantly to the mathematics profession as Associate Editor for the American Mathematical Monthly – the most widely read mathematics journal in the world. She is also an active member of SIAM, a professional society for applied mathematics, where she helps organize meetings and contributes to administrative efforts and regularly serves as a grant evaluator for the NSF and the Simons Foundation, helping to shape the future of mathematical research.

Virginia Lesser, Department of Statistics Head, received the Champion of Science award for her significant contributions to the field of statistics and to Oregon State University throughout her distinguished career. After earning her PhD in Biostatistics from the University of North Carolina at Chapel Hill, she joined OSU’s Department of Statistics in 1992.

A year later, she became Director of the Survey Research Center, a role she held until her retirement in December 2024. Lesser's expertise in probability sampling, survey design, and data collection methods ensured that the center upheld the highest standards. Under her leadership, the center became a premier institution, offering expertise in survey methodology, sampling and data analysis – supporting projects that inform policy, environmental monitoring, economic studies and public opinion research. Its work has helped agencies such as the Oregon Department of Transportation, the Oregon State Marine Board, and the Oregon Department of Fish and Wildlife make data-driven decisions, not to mention numerous initiatives within the University.

Lesser's groundbreaking research in survey methodology, environmental statistics, applied statistics and ecological monitoring has advanced the field and influenced practice. She has authored over 55 journal articles and conference proceedings, earning national and international recognition – including being named a Fellow of the American Statistical Association and an elected member of the International Statistical Institute.

Lesser's leadership also transformed the statistics department and elevated Oregon State University’s role in the field as department head from 2011 to 2018.

Lesser has also been a dedicated mentor and advocate for students and colleagues. Over the course of her career, she guided more than 220 graduate students and fostered a welcoming, supportive community within the department. Her colleagues regard her as an exceptional mentor and an inspiring leader, someone who consistently goes above and beyond – whether leading major academic initiatives or simply making sure the department potluck had a home-cooked turkey.
