I am a second year Computer Science PhD student at Stanford University interested in operating/distributed systems and computer architecture. I work with Professor Keith Winstein, and John Ousterhout. Currently we are developing a reprogrammable Network Interface Card capable of implementing a diverse range of transport protocols entirely in hardware. Early work on this project has focused on deploying the Homa transport protocol on a Field Programmable Gate Array. I am also interested in the effect of Bias Temperature Instability, a form of transistor degradation, on the security of hardware systems. Advised by Professor Dustin Richmond, Ryan Kastner, and David Kohlbrenner, I am exploring the feasibility of this side-channel in cloud deployments of Field Programmable Gate Arrays (FPGAs). Our recent results have demonstrated that sensitive data loaded into a cloud-FPGA's routing at runtime is imprinted in the device via variable transistor wear, and this side-channel can be exploited by a future user of the device through the instantiation of a precise timing sensor in its programmable fabric. This work builds off the results of my work at the University of California San Diego, where I completed my BS and MS degree. My research focused on power side-channels in cloud FPGAs but later pivoted to the transistor side-channels being explored currently. I was advised by Professor Ryan Kastner and Dustin Richmond and my thesis was supervised by Professor Ryan Kastner, Deian Stefan, and Dean Tullsen.
