Hi, I'm Raymond 👋

I'm a researcher and scientist with interests in AI/ML, statistical methods (Bayesian inference), software, high-performance (scientific) computing, and data analysis. I'm currently looking for computation/engineering/research scientist roles in AI/ML for science.

Previously, my research studied the forces that hold matter together and the physics of the early universe about 1 microsecond after the big bang via high-energy collisions of nuclei, sometimes described as "little bangs", at the Large Hadron Collider at CERN in Geneva, Switzerland.

More specifically, I've been an experimental physicist with a focus on studying high momentum transfer processes known as jets, with a particular interest in jet substructure. These jets are used as calibrated probes to study quantum chromodynamics (QCD) and the quark-gluon plasma (QGP) formed in heavy-ion collisions. My main research activities included experimentally measuring jet observables as a member of the ALICE (A Large Ion Collider Experiment) collaboration, as well as using these measurements to perform rigorous extractions of fundamental physics parameters via statistical methods (ie. Bayesian inference) as a member of the JETSCAPE collaboration.

Most recently, I was an assistant project scientist at UC Berkeley and Lawrence Berkeley National Lab.
