Katherine Masyn is an associate professor of  Epidemiology and Biostatistics for the School of Public Health. Previously she worked as an associate professor at the Harvard Graduate School of Education. She earned her BS in Mathematics from the College of William and Mary, MA in Biostatistics from UC Berkeley, and PhD in Advanced Quantitative Methods in Social Research at UCLA under the mentorship of Bengt Muthén. She worked as a postdoctoral fellow on a NIH Prevention Science training grant through the Johns Hopkins Bloomberg School of Public Health (P.I., Nick Ialongo) before joining the UC Davis Human Development faculty in 2005. Katherine’s research focuses on the development and application of latent variable statistical models related to: survival and event history analysis; multivariate and multi-faceted longitudinal processes, e.g., latent transition growth mixture models; and, more broadly, the characterization and parameterization of both observed and unobserved population heterogeneity in cross-sectional and longitudinal settings, e.g., factor mixture models. Along with her own methodology research, Katherine enjoys close collaborations with colleagues from the fields of Public Health, Prevention Science, Education, and Psychology, and serves as the statistical consultant on multiple federally-funded research grants.
