Alejandro Gomez Espinosa Ph.D.

Experimental Particle Physicist

Welcome to my corner of the web. Here, I share my research, projects, academic journey, and thoughts on physics and computing.

I am an Experimental Particle Physicist and Postdoctoral Researcher at Carnegie Mellon University, specializing in high-energy collisions and advanced data analysis for the CMS Experiment at CERN. With over a decade of research experience across leading institutions—including Fermilab, ETH-Zurich, Rutgers University, and Carnegie Mellon University—my work sits at the intersection of fundamental physics, high-throughput computing, and reproducible data science.

My primary research focuses on searching for new physics and measuring standard model phenomena, with a particular interest in di-Higgs physics and the precision reconstruction and calibration of jets. Analyzing petabyte-scale datasets from the Large Hadron Collider (LHC), I develop robust data-driven frameworks using C++ and Python, incorporating machine learning and cloud computing to optimize event reconstruction.

As a strong advocate for open science, I actively work on workflow orchestration and analysis reproducibility to make high-energy physics research more accessible and sustainable. I thrive in large, multicultural collaborations, leading international teams within the 4,000+ member CMS Collaboration and regularly communicating scientific results to global audiences of over 500 stakeholders.
