Cirriculum vitae

Research Interests:

I am interested in theoretical problems at the interface of physics and biology (and more and more these days Machine Learning).  I want to understand how large-scale, collective behaviors observed in biological systems emerge from the interaction of many individual components -- whether it be molecules that allow cells to do complex computations, the emergence of cell fate in development, or trying to identify and explain the emergence of universal statistical behaviors in microbial ecosystems. I also have a deep interest in unsupervised learning methods in Machine Learning.

I am a theoretical physicist but the group's research in quite inter-disciplinary. I am part of the BU Microbiome Initiative, BU Bioinformatics Program, the BUMC Center for Regenerative Medicine (CReM), and the BU Biological Design Center. To find out more about my research please look at my publications with links to pdf files. Beyond science, I have a running interest in radical politics, sociology, and political economy (much of which I have learned from some wonderful teachers). Some of my writings can be found here.

Code generated by the group can be found here.

Machine Learning Review

Our new Machine Learning review is finally done! Check it out and the 20 Python Notebooks here.

Reinforcement Learning agent learns about Quantum Mechanics

These movies are fun, especially this overview movie.
