Nancy A. Perrin, PhD

Senior Investigator
Assistant Program Director
Nancy Perrin

Dr. Nancy Perrin is an expert in the application of multivariate statistical techniques to health outcomes. As part of her interest in working with "messy data,” she uses a variety of designs and statistical methods in her research. She specializes in longitudinal data and statistical modeling in her current collaborations on a number of NIH-funded studies.

Dr. Perrin has been working with Dr. Adrianne Feldstein to uncover trajectories of weight loss or gain in patients with diabetes or cardiovascular disease. This project uses longitudinal data analyses to estimate individual weight trajectories and the relationship between these trajectories and future health outcomes. Dr. Perrin is also conducting research with John Hopkins University to support victims of domestic violence. Specifically, she is developing measures to understand workplace culture toward domestic violence and performing cluster analysis to determine what types of domestic-violence support women want from their supervisors.

Dr. Perrin came to CHR from Oregon Health & Science University, where she was director of the statistical core. She retains an adjunct professor appointment there. A former professor and associate dean at Portland State University, Dr. Perrin received her BA from University of California, Los Angeles, and her master’s and doctoral degrees from Ohio State University.
