Research Interests

Dan is a Professor of Computer Science at Columbia University whose research traditionally focuses on the resilience, performance, and security of complex networked systems.

Recent interests also include foundations of Quantum Computation, Quantum Resilience, and Quantum Networking. His past research made significant contributions to Wireless and Sensor Networks, Overlay/P2P Networking, and Multimedia and Content Distribution, specifically in the development of robust distributed algorithms and foundational models for large-scale media delivery. He co-directs the DNA Lab—currently being renamed QuAINt (Quantum, AI, NeTworking)—alongside Vishal Misra.

Since 2020, Dan has also been employed at Google, assisting with the design of scalable algorithms for massively distributed systems and denial-of-service protection and prevention. In the past, Dan has also provided technical consulting and served as an expert witness in patent litigation matters involving IP telephony, media streaming, and network protocols.

He is an IEEE Fellow, a recipient of the NSF CAREER Award, an IBM Faculty Award, and a recipient of several Best Paper Awards in IEEE and ACM-sponsored conferences, including twice at ACM CoNEXT (2008, 2011), as well as at IEEE ICNP and ACM SIGMETRICS.

He earned his B.S. in Mathematics from MIT, an M.A. in Mathematics from UCLA, and a Ph.D. in Computer Science from the University of Massachusetts Amherst. He grew up in Brooklyn, NY and attended Stuyvesant High School.
