Calvin Beideman

I am a fifth-year PhD student at the University of Illinois Urbana Champaign (UIUC), where I am thankful to be advised by Karthekeyan Chandrasekaran. Before coming to UIUC, I studied at Carnegie Mellon University, where I obtained a Bachelor of Science in Computer Science with an additional major in Mathematical Sciences (Discrete Mathematics and Logic) with University Honors. There I had the good fortune of working under Ryan O'Donnell on my honors thesis. I also had the pleasure of doing research with Anil Ada and of working with him in the development of the course 15-251: Great Ideas in Theoretical Computer Science.
