Nathan Manohar

I am a fourth year computer science PhD student at UCLA. I am very fortunate to be advised by Prof. Amit Sahai. My main research interests are cryptography, computer security, and, more broadly, theoretical computer science.

During the summer of 2020, I interned at the IBM T.J. Watson Research Center, where I worked with Dr. Charanjit S. Jutla and Prof. Victor Shoup.

I received a bachelor's degree in Computer Science and Mathematics and a master's degree in Computer Science from Harvard University in 2016. I spent a year as a graduate student researcher at Stanford University, where I worked with Profs. Dan Boneh, Mary Wootters, and Moses Charikar.

News

We developed a dedicated hardware-based solution for Bluetooth-based contact tracing that is based on current public health guidelines for COVID-19. The solution preserves the privacy of participants until they come in contact with a known positive user, at which point the contact is revealed to public health officials to supplement their manual contact tracing efforts. Our approach balances individual privacy with the needs of public health officials and is more accurate than using phones. The paper can be found here.
