Rishab Nithyanand, Ph.D.

Assistant Professor

Rishab Nithyanand is an Assistant Professor in the Department of Computer Science at the University of Iowa where he leads the Security, Privacy, and Anonymity Research Team (SPARTA) Lab. 

Research Interests

My research interests are in the areas of security, privacy, and Internet measurement. More specifically, I enjoy research geared towards defending anonymity, understanding Internet censorship, measuring aspects of the advertising and tracking ecosystem, and generally understanding the impact of the Internet on the sociopolitical realities of today. In the past, I dabbled in usable security and computer theory.
