I am a third-year Ph.D. student advised by Rodrigo Fonseca, primarily interested in networks, distributed systems, and security. I am supported by an NSF Graduate Research Fellowship.

I completed my undergrad at the University of Washington where I studied computer science. During my time at UW I primarily worked with Justin Cappos on topics related to sandbox security and API Write-Once-Run-Anywhere verification.

I also worked on the GENI supported peer-to-peer testbed called Seattle.

More details can be found in my CV.

Low-latency Network Monitor and Control Methods

Software-defined networking introduces the possibility of building self-tuning networks that constantly monitor network conditions and react rapidly to important events such as network congestion. Unfortunately, state-of-the-art monitoring mechanisms for conventional networks require hundreds of milliseconds to seconds to extract global network state like global link utilization or the identity of "elephant" flows. My work in this area looks at improved techniques for measuring and controlling high-speed 10GbE or higher data center networks. This is ongoing work with my colleagues at IBM Research and Brown.

Network Impact of DISC Frameworks

Data Intensive Scalable Compute (DISC) frameworks such as Hadoop and Spark are becoming increasingly important tools for many institutions. Inherently the network is a key factor in the performance of these frameworks, yet this interaction is still poorly understood because of the growing complexity of applications and large shared data center infrastructures. My work in this area is a systematic study of the impact between the network and the end-to-end performance of DISC framework applications.
