Post-doc at Baylor College of Medicine/Rice University (2023)
Worked with Ankit Patel at the intersection of AI and Biology/Medicine
- Understanding Gene Regulatory Network (GRN) evolvability through evolutionary simulations. See extended abstract “Binding affinity distributions drive adaptation in GRN evolution” at ALIFE 2023
- Using (SOTA) LLMs to analyze Semi-Structured Healthcare interviews. (Nearing pre-print stage)
- Characterizing the evolution of molecular markers of Myelodysplastic Syndrome (MDS) in multi-omic liquid biopsies. (In progress)
Post-PhD Industry (2022)
Research Scientist in Machine Learning in the Probability team team at Meta. Worked on team proojects involving:
- Uncertainty Quantification using Neural Networks (Deep Ensembles, MCMCDropout, …)
- Bayesian Modeling for Online Experiments (primarily using sampling-based inference from the in-house Bean Machine PPL)
PhD (9/2017 - 12/2021)
- PhD at the University of Washington (Seattle), at the intersection of ML/RL and Computational Neuroscience. Advised by Bingni W Brunton (UW Neurobiology) and Rajesh PN Rao (UW Computer Science).
