I am a senior studying Electrical and Computer Engineering at Carnegie Mellon University.
I am advised by Prof. Brandon Lucia and a member of the ABSTRACT research group.


I am interested in doing research on the boundary of computer architecture and computer systems, with a particular emphasis on optimizing computing performance and efficiency beyond traditional scaling.

I am currently working on projects centered around the themes of energy-minimal computing, parallelism, and concurrency:

Research on the memory consistency model of a threaded Coarse-Grained Reconfigurable Architecture (CGRA).
Problem: Pipestitch is a CGRA with lightweight threads. When a Pipestitch program has multiple threads that communicate through memory, it is possible for the execution to violate Sequential Consistency (SC). To solve this problem, additional program analysis by the programmer/compiler and excessive fence placements are required.
Goal: Automatically enforce SC ordering at a low cost by adding microarchitectural support in a Pipestitch-like architecture.

Research on asynchronous programming for energy-minimal dataflow architectures.
Problem: Excessive operation reordering and synchronization is required for applications with irregular memory access patterns to run on resource-constrained CGRAs.
Goal: Explicitly express parallelism amenable to dataflow execution and the underlying CGRA architecture.
