About Me

I am a fourth year PhD candidate in the ECE department at the University of Wisconsin-Madison, advised by Professor Ramya Korlakai Vinayak. I am interested in crowdsourcing, preference learning, and the application of machine learning algorithms. I received my B.A. in Computer Sciences and Mathematics with Honors from the University of Wisconsin-Madison as well. 1 + 1 < 3   My CV.
