Academic Bio:

I am a Ph.D. student in CS at University of Wisconsin – Madison where I am advised by Fred Sala. Before that, I had the pleasure of working with Ameet Talwalkar and Zack Lipton during my MS at Carnegie Mellon University. As an undergraduate, I was extremely fortunate to work with both Sanjoy Dasgupta and Gary Cottrell at the University of California, San Diego. Before that, I was a community college student at Fresno City College, where I was lucky enough to learn calculus, linear algebra, and C++ from Greg Jamison.

Research Interests:

I am interested in making machine learning more accessible and applicable to new domains. Recently, I’ve been working on automated dataset construction and model selection for diverse tasks—i.e., beyond well-explored domains in ML such as vision and language.
