  • Departmental Early Career Fellow

I develop statistical and computational methods to characterize the interplay between morphology and genomics in the early development of organisms. 

 

 

Biography

Previously, I was a Member in the School of Mathematics at the Institute for Advanced Study (IAS).

I received my PhD in Computational Biology from Princeton University. Before that, I did my undergraduate

studies at MIT where I earned a B.S. in Mathematics.

Research

My long term goal is understanding how single cells aggregate temporal and spatial, chemical and physical

information to make decisions about their identity, and how these decisions can be altered through optimal

perturbations and experimental design. Informed by both experiment and theory,

I am interested in interpretable and principled techniques, deep and shallow alike,  with roots in

hypothesis testing, domain adaptation, representational learning, and active learning.

 

Current research directions and projects include:

* interpretable dimensionality reduction, linear and non-linear, for single cell gene expression studies

* multi-modal models of morphology, gene expression and epigenetics for the study of the early mouse embryo

* experimental design of combinatorial perturbations 

* statistics of organic pattern formation and synchronization phenomena

* interpretable models for multi-agent trajectory prediction
