Research and Experience

I’m a Computer Science Ph.D. Student at Northwestern University. I’m part of the Prescience Lab at Northwestern, led by Peter Dinda. Broadly, my interests lie in the realm of high-performance computing, extremely heterogeneous systems, and performance portability. More specifically, I’m interested in improving the utilization of diverse hardware resources within/across systems by looking at solutions bridging layers of the hardware-software stack.

Northwestern University | September 2021 - Present

I am currently a second-year Ph.D. student on the Systems track in Computer Science at Northwestern University. I’m interested in extreme heterogeneity as it relates to HPC systems.

Clemson University | August 2016 - May 2021

I graduated in May of 2021 with a degree in Computer Engineering from Clemson University. Some of the courses I have taken include: HPC Fault Tolerance, Digital Design using VHDL, Computer Organization, Embedded Computing, GPU Programming, and Operating Systems. In addition to my degree, I also obtained a minor in Spanish Studies.


Northwestern University | PhD Student | September 2021 - Present

I’m currently a second-year PhD student, part of the Prescience Lab at Northwestern University. My research focuses on addressing challenges related to extreme heterogeneity in future parallel, distributed, and HPC systems through HW/SW Co-design of programming languages, compilers/runtimes, and architectures.

Sandia National Laboratory | R&D Intern - Grad | June 2022 - September 2022

Over the summer of 2022 I worked as an R&D Intern in the Scalable Algorithms Group at Sandia National Laboratory. My work involved evaluating novel architectures for viability in future heterogeneous systems. I focused on Nextsilicon’s HPC focused architecture and toolchain, as well as it’s interaction with the Kokkos programming model for performance portability.
