I am a PhD student in the Computer Science Department at Carnegie Mellon advised by Prof. James C. Hoe and doing research in the area of Computer Architecture as a member of the Computer Architecture Lab at Carnegie Mellon (CALCM). Currently, my research focuses at the intersection of Networks-on-Chip (NoCs) and reconfigurable computing, particularly in the form of FPGAs and CoRAM.

As part of my research I recently developed CONNECT, a fast lightweight and flexible NoC architecture to support the communication needs of current and future FPGA applications. The CONNECT NoC architecture embodies a set of FPGA-motivated design principles to make the most efficient use of the FPGA substrate.

In an effort to create a useful research tool for the community, in March 2012 we publicly released CONNECT in the form of a flexible user-friendly web-based NoC generator that supports a variety of common network topologies, as well as custom user-configured networks that can be created through a visual network editor.

My recent work on Networks-on-Chip also includes FIST, a set of fast, lightweight, FPGA-friendly NoC modeling techniques to replace time-consuming detailed NoC models in full-system performance simulators. In the past I worked on the ProtoFlex project, which is part of the multi-university RAMP initiative. This work included the development of FPGA-accelerated instrumentation components to study multiprocessor cache hierarchies and branch predictors. I have also worked on the problem of memory scheduling and co-authored a paper on "Thread Cluster Memory Scheduling", a new memory scheduler that exploits differences in the memory behavior of threads to maximize system throughput and fairness (IEEE Micro 2010 Top Picks paper).

In 2011, I participated in the Memocode Hardware/Software Codesign Contest, which required the development of a fast simulator for a diverse class of NoCs. Our FPGA-based submission, detailed in this invited MEMOCODE 2011 paper, won the first place in the "Absolute Performance" category.

While at CMU I have collaborated with various students and faculty, including Eric Chung, Yoongu Kim, Prof. Ken Mai, Prof. Babak Falsafi, and Prof. Onur Mutlu. During my 2010 internship at Intel Labs, I worked with Graham Schelle and Hong Wang in the Microarchitecture Research Lab (MRL) on uncore modeling for future multi-core systems.

I am currently serving as the Computer Science Department Graduate Student Ombudsperson. The best way to contact me is via email at .
