About Me

I am a Ph.D. student at U.C. Berkeley interested in statistics and machine learning. Before coming to Berkeley, I was a student at Arizona State University, where I studied mathematics and economics, and completed a master’s thesis under Sebastien Motsch in the mathematics department. Outside of university, I was recently a research intern at Salesforce Research, and have also worked for Amazon.com in the past. See my CV for more.

Photography

I love to travel and spend as much time outdoors as possible. I always take my camera with me wherever I go - feel free to check out some of my photos.

Research

Since coming to Berkeley, I have been primarily interested in various theoretical aspects of deep learning, though lately this has mainly been focused on the question of generalization. Namely, I’m interested in when and how we can fit extremely complicated and expressive models to data, and expect these models to perform well on new, unseen data.

Below is a list of papers I’ve co-authored.

Theisen, R., Klusowski, J. M., Wang, H., Keskar, N., Xiong, C., Socher, R. Global Capacity Measures for Deep ReLU Networks via Path Sampling. Submitted, 2019. [ArXiv]
