I'm an Assistant Professor of Computer Science at Swarthmore College. I have most recently been a post-doctoral scholar at UMass, Amherst, where my advisors were Prof. Jim Kurose and Prof. Arun Venkataramani. My research interests are in design and evaluation of next-generation network architectures, enabling device and content mobility in the Internet, and performance modeling and data analysis of large-scale networks.
