experiences

Below are my “formal” work experiences. I also contribute to several open-source scientific software, and I consider that as an “experience” too (see /opensource). I have also mentored several students and researchers who are new at writing code for research/scientific software (see /service).

Research Software Intern (bachelor’s thesis)

CERN, Princeton University

Dr. Jim Pivarski (Princeton University)

January 2024 - Present | Meyrin, Switzerland

• Carrying out computational upgrades on the high energy physics data analysis pipeline for future LHC/HL-LHC runs.
• Enabled auto-diff in Scikit-HEP; migrated Coffea’s vector algebra backend; implemented non-uniform rebinning (UHI) in boost-histogram; developed a symbolic backend for Vector; prepared Vector for HL-LHC upgrades; working on bringing histograms to GPUs.

Visiting Student Researcher (Mitacs Globalink Research Intern)

McMaster University

Prof. Jacques Carette

June 2023 - August 2023 | Hamilton, Ontario, Canada

• Formalised Mathematics and Computing in Agda’s (a dependently typed functional programming language and an interactive theorem prover) standard library using Type Theory, Proof Theory, Functional Programming, and Computational Logic.
• Refactored the standard library’s codebase for v2.0, simplified the dependency graph, fixed various bugs, and added new functions and mathematical proofs.
