News Flash: As of July 2022 I have joined AMD Research full time as a MTS Silicon Design Engineer. I will be finishing my PhD while working at AMD.

Bio

Research Interests

My research interests are in the field of computer architecture and revolve around (a) cache coherence, specifically for in-order multicore processors, (b) open-source hardware design, (c) programmability in the memory system, (d) general purpose parallel computing (e.g., GPGPU-styled architectures), and (e) hardware specialization.

My current research is centered around the design and implementation of the cache coherence protocol for the open-source BlackParrot RISC-V multicore processor. I am the lead architect and developer of the cache coherence protocol and its associated programmable and fixed-function coherence engines. The design and implementation of BlackParrot is fully open-source. Accelerating the adoption of open-source hardware requires not only an open ISA, but also open-source implementations that can be easily taken from RTL to tapeout.

Aside from technical research, I am also very interested in computer engineering education and curriculum. As the underlying technology of computing systems changes, how should that change the curriculum we provide and teach? How do we design and teach courses in an equitable, inclusive, and productive (for both learner and teacher) way?

My past research has spanned a variety of topics, including data processing for novel DNA sequencing technology, modeling approximate computing techniques (see REACT), and the evaluation and comparison of a neural network accelerator on reconfigurable hardware using high level synthesis (see SNNAP).
