PNNL

Dr. Eva Brayfindley, PhD, is a senior data scientist on the Chemical and Nuclear Defense team within the Applied AI Systems group at Pacific Northwest National Laboratory (PNNL). Her current work focuses primarily on statistically driven data science and machine learning for applications in cheminformatics and nuclear safeguards applications, where data is often limited and analysis results need to be highly validated and explainable. Before her current role at PNNL, Dr. Brayfindley worked as an associate data evaluation officer at the International Atomic Energy Agency in Vienna, Austria, providing statistical analysis support to safeguards inspections within the Safeguards Information Management division. Dr. Brayfindley received her BS in chemistry from the University of San Francisco in 2014. She then went on to receive her MS and PhD in applied mathematics at North Carolina State University, as well as a graduate certificate in Nuclear Nonproliferation Policy and Technology. In her free time, she enjoys hiking, running, and baking.
