Selected Course Projects

2025

Predicting Fitness Effects of Synonymous Mutations

10-710 Computational Genomics, CMU

Curated a dataset integrating genomic, evolutionary, kinetic, and structural features of synonymous mutations in S. cerevisiae and built interpretable models predicting fitness effects of synonymous mutations.

2025

Probing Chirality in E(3)-Equivariant Boltzmann Generators

MSCBIO 2030 Computational Structural Biology, Pitt

Demonstrated that SO(3)-equivariant Boltzmann generators are necessary to capture chirality in molecular structures and latent representations, with implications for using traditional E(3)-equivariant models for modeling biomolecular systems and drug design.
