  • Perform performance sensitivity studies of water-based radiation detectors, including for nonproliferation applications of reactor neutrinos.
  • Perform simulations to guide the design of water-based detector systems.
  • Lead experimental efforts at LLNL to evaluate and qualify detector components.
  • Validate simulation models with experimental detector data.
  • Supervise testing, measurement, and analysis work by graduate students.
  • Publish peer reviewed journal articles summarizing research findings.
  • Provide technical contributions to the development of future experiments.
  • Work in close collaboration with colleagues at LLNL and the broader neutrino science community.
  • Perform other duties as assigned.







  • PhD in High-Energy Physics, Nuclear Engineering, Nuclear Physics, Particle Physics or a closely related field.
  • Experience with GEANT4-or MCNP based simulation tools.
  • Experience in C++/Python, ROOT, and other programming languages.
  • Experience in analysis of data from multi-channel detector systems.
  • Experience in simulating physics processes and detector response in experiments.
  • Experience with data analysis and interpretation.
  • Proficient verbal and written communication skills.
  • Ability to collaborate effectively in a team environment.


Qualifications We Desire





  • Experience in nuclear nonproliferation.
  • Experience in organic scintillator development.
