PhD (December 2019), Neural Computation and Machine Learning, Carnegie Mellon University

I have a PhD in Machine Learning (School of Computer Science) and Neural Computation (Center for Neural Basis of Cognition) from Carnegie Mellon University (Dec 2019).

Like my PhD advisor, Robert E. Kass, my work is in Statistics and Machine Learning methodology applied to Neuroscience problems. My thesis is on graphical network modeling of brain region interactions during working memory tasks. I am also interested in the cognitive science of learning and I’m part of the CMU Teach Stat research group.

About my work:

Complex behaviors like memory recall require the coordination of multiple brain regions; I study cross-region coordination using network graphs, where the nodes represent noisy activity from different brain regions. I develop methods for graphical model structure learning for high-dimensional data.
