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.

Some Current Projects
Verbal Autopsy: probabilistic framework to infer cause-of-death assignments and population-level distribution from noisy high-dimensional survey data.
Papers: BA'19, AOAS'20, JASA'16
openVA: a collection of open-sourced tools that implements a standardized pipeline to process and code verbal autopsy data using multiple algorithms.
Papers: Vignette'19, Preprint'18
Small-Area Estimation using complex surveys. News: In close coordination with UN IGME, we have produced subnational under-five mortality estimates. See press release here.
Papers: PLoS'19, Vignette'20
Spike-and-slab priors for Gaussian, copula, and joint graphical models that allow fast posterior exploration of graph structures with less bias.
Papers: ICML'19, JCGS'19
COVID-19: model-based projections; prevalence estimation; and assessing the impact on population mortality.
Papers: MedRxiv'20 arXiv'20
