About Me

I am a postdoc at Johns Hopkins University working with Professors Suchi Saria and Michael Rosenblum. I completed my PhD in 2018 at UMass working in the Machine Learning for Data Sciences lab with Prof. Benjamin Marlin.


Previous courses

COMPSCI 590N: Introduction to Numerical Computing with Python

Research Interests

I am interested in probabilistic and latent variable modeling, inference methods for these models, and the application of these models to problems in health and ecology.
