Education

PhD Chemistry, University of California, Davis, 2019.

BS Chemistry, University of California, Davis, 2012.

Research

Computational chemistry, medicinal chemistry, and machine learning.  I develop machine-learning models - 3D convolutional neural networks - for docking-pose classification to enable improved high-throughput virtual screening.  I also generate atomistic-resolution protein structural models and dock small molecules to these models to understand molecular mechanisms of action. I'm also interested in structure/ligand-based drug design.
