About Me

I am a PhD candidate in Computer Science at UMass Amherst. I work in the Machine Learning for Data Sciences lab with Prof. Benjamin Marlin.


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.
