About Me

I am a final-year Computer Science PhD student at Texas A&M University working under Daniel A. Jiménez. My work focuses on making hardware predictive structures and policies (e.g., branch prediction, prefetching, cache replacement) more resilient to evolving computing demands. I hold a BSc in Computer Science from Columbia University, and an MSc in the same from Princeton University. My work has been featured in top-tier computer architecture conferences, including ISCA and MICRO. My research has received accolades, including the 2020 IEEE Computer Society Lance Stafford Larson Student Award. I was also named a 2020 Rising Star in EECS and was named a 2021 Google Scholar.

After returning to graduate school for my PhD and seeing fellow graduate students struggle with mental health issues and the general toll of graduate students, I helped co-found the Computer Architecture Student Association, or CASA. CASA is an independent student-run organization whose mission is developing and fostering a positive and inviting student community within computer architecture. Upon graduation, I hope to continue helping students at all levels by entering academia in a teaching-track professorship role.

Below are my academic statements:
