I am an Assistant Professor in the Department of Statistics at University of California Santa Cruz. I am broadly interested in statistical methods and tools to address scientific questions in demography, epidemiology, and global health. Currently I work on latent variable modeling in messy, high-dimensional data, space-time models, causal inference, and applications in health data science.
I was previously a postdoctoral researcher working with Forrest Crawford in the Department of Biostatistics at Yale School of Public Health. I received my Ph.D. from the Department of Statistics at the University of Washington, advised by Tyler McCormick.
My research is generously supported by the National Institutes of Health, Melinda and Bill Gates Foundation, Vital Strategies, the Hellman Fellows Program, UCOP, and UCSC.
