Juan Manuel Cruz Martinez, PhD

Theoretical physicist, scientific-computing enthusiast, occasional sysadmin.

I am currently a Ramón y Cajal fellow in the Department of Atomic and Nuclear Physics of the University of Sevilla.

Previously I was a CERN senior fellow in the Theory group and a postdoc at the Department of Physics of the University of Milan, as part of the N3PDF team. I did my PhD at Durham University.

My research focuses on precision QCD, proton structure and scientific computing for the LHC, sitting at the intersection between High Energy Physics (HEP) and High Performance Computing (HPC).

I am the Research & Development coordinator of the NNPDF collaboration, where we utilize Machine Learning techniques to model the partonic structure (quarks and gluons) of the proton in highly energetic collisions. I also develop several computing tools dedicated to state-of-the-art high precision calculations using either novel methodologies or pioneering new hardware in particle physics, such as Graphics Processing Units (GPUs) or Quantum Computers (QC). To make a long story short, I have worked on percent-level proton structure, intrinsic charm, LHC phenomenology, and occasionally on persuading GPUs and quantum circuits to do particle physics.

Outside of research (but not far removed), I am a strong proponent of open-source software and try to contribute whenever life allows, and I enjoy the tumultuous world of system administration. So if you are a student or young researcher interested in theoretical physics, computing, or both, feel free to drop by or send me an email.

You can contact me by email, bluesky or messenger pigeon.
