Professional Background

Vincent Cheung received his PhD in high-energy nuclear physics from the University of California at Davis in 2020 where he investigated quarkonium polarization in high-energy collisions. He pioneered the improved color evaporation model to produce the first quarkonium polarization predictions using the model.

Vincent joined as a postdoc at the Lawrence Livermore National Laboratory in 2021 to continue investigating nuclear structure in particle collider environments such as the Large Hadron Collider and the future Electron Ion Collider. He was awarded a Lab-Wide Lab Directed Research and Development award to investigate the nature of the X(3872), a tetraquark candidate.

In 2023, Vincent was converted to a staff scientist. He then expanded his expertise in nuclear physics by also contributing to nuclear data infrastructure development and radiation modeling for nuclear nonproliferation and security purposes.
