Nirav Atre
Ph.D. Student in Computer Science
Carnegie Mellon University
I am a Ph.D. candidate in the Computer Science Department (CSD) at Carnegie Mellon University (CMU), where I’m fortunate to be advised by Prof. Justine Sherry. My research area is computer networking, and I’m part of the SNAP Lab at CMU; I’m secondarily affiliated with CONIX, CyLab, and CMU’s Parallel Data Lab (PDL). My research interests broadly lie at the intersection of systems and analytical modeling: methodically building networked systems and proving useful theoretical properties about their performance, scalability, and attack resiliency. Prior to starting graduate school, I obtained an undergraduate degree (B.A.Sc.) in Computer Engineering from the University of Toronto, Canada.
I’m beyond excited to be joining the Computer Science Department at Stanford University as an Assistant Professor starting Fall 2026! Until then, I will be a Visiting Researcher on Jane Street’s Ultra Low Latency (ULL) hardware team in New York City.
