Yen-Jie Lee

Yen-Jie Lee is an Associate Professor of Physics at MIT, affiliated with the Laboratory for Nuclear Science. He specializes in experimental particle physics, focusing on proton-proton and heavy-ion collisions to study quark-gluon plasma and high-density QCD phenomena. His work utilizes the Large Hadron Collider (LHC) and CMS collaboration data.

Education: B.Sc./M.Sc. in Physics from National Taiwan University (Belle collaboration), Ph.D. from MIT (2011, advised by Wit Busza). Postdoctoral research at MIT's Laboratory for Nuclear Science, followed by a CERN Marie Curie Fellowship (2012-2013). Joined MIT faculty in 2013, promoted to Associate Professor in 2018.

Research Interests: Heavy-ion physics, jet quenching, energy-energy correlators, QCD dynamics, and experimental techniques in high-energy physics. His contributions include pioneering studies of high-density QCD using electron-positron annihilation data and demonstrating the mathematical prediction for infinitely long coupled systems with Bell Lab machines.

Key Achievements: Over 150 publications, major awards include the DOE Early Career Award (2015), Sloan Fellowship (2016), and PECASE (2019). Leads the Relativistic Heavy Ion Group at MIT, contributing to CMS collaboration analyses on jet substructure, heavy flavor production, and medium response studies in heavy-ion collisions.

Grants & Collaborations: Active in LHC experiments, CMS collaboration leadership roles (e.g., Heavy Ion Physics Group co-convener), and grants from DOE and MIT. Collaborates internationally with institutions like CERN and national laboratories.
