Prof. Aleksandr Aravkin
Dr. Aleksandr Aravkin is a statistical expert witness and tenured faculty member at the University of Washington, where he serves as Associate Professor of Applied Mathematics and Director of Mathematical Sciences at the Institute for Health Metrics and Evaluation (IHME). He brings more than 15 years of hands-on experience building, validating, and explaining complex statistical models—expertise he applies to high-stakes litigation across civil and criminal matters.
Dr. Aravkin has worked with multiple state Attorneys General (Washington, Colorado, Oregon, Kansas) and top law firms including Perkins Coie, Pillsbury, and Ballard Spahr. He has been deposed seven times and is known for delivering clear, defensible, and practical testimony. His litigation work spans election analytics, COVID-19 business-interruption claims, medical malpractice, damages estimation, general statistical analysis, and custom data analyses tailored to case-specific questions, including translating physical scenarios into quantitative models that assess risk, likelihood, and causation.
At IHME, Dr. Aravkin leads the scientific team responsible for many of the statistical and computational methods behind globally recognized estimates of disease burden as well as global forecasting and epidemiological platforms. His group develops large-scale systems for modeling causation, uncertainty, time trends, and incomplete or noisy datasets—skills that directly translate to analysis of legal disputes informed by available data.
With more than 170 peer-reviewed publications in leading journals such as The Lancet, Nature Medicine, JAMA, Journal of Computational and Graphical Statistics, Journal of Machine Learning Research, and the Journal of the American Statistical Association, Dr. Aravkin is internationally recognized for advancing robust, transparent, and well-validated methods. He specializes in clarifying what the data actually shows, what it does not support, and how competing statistical claims compare.
Dr. Aravkin is particularly effective at translating complex modeling into clear, courtroom-ready explanations. He works closely with legal teams to evaluate evidence, identify weaknesses or strengths in opposing analyses, and present findings in a straightforward manner that judges and juries can understand.

- Q: Please list your professional accreditations, degrees, licenses, and certificates granted:
- A: Ph. D. Mathematics
M.S. Statistics
B.S. Computer Science & Mathematics - Q: Please list any teaching or speaking experience you have had, including subject matter:
- A: I teach a variety of graduate and undergraduate courses at the University of Washington focused on statistical modeling, optimization, scientific computing, and machine learning.
I also speak regularly at leading conferences and workshops in applied mathematics, statistics, machine learning, and data science. Recent invited venues include the Society for Industrial and Applied Mathematics (SIAM) Conference on Optimization, the International Conference on Continuous Optimization (ICCOPT), the Institute of Applied Mathematics at the University of British Columbia, and the Mayo Clinic’s COVID-19 Webinar Series, as well as seminar series hosted by institutions such as Stanford University, McGill University, and the Canadian Mathematical Society.
My recent presentations have addressed broad topics such as robust statistical inference, large-scale and nonconvex optimization, statistical methods for global health, forecasting and scenario modeling, statistical raking, new developments in optimization methods, modeling risk–outcome relationships in global health data, variable-selection methods for regression, and methods for COVID-19 forecasting.
