The Particle Astrophysics Group in the Department of Physics at Brown University will have an opening for a postdoctoral research associate starting August 1, 2024 or earlier if desired. Timing can be negotiated. The position will involve working on the LUX ZEPLIN (LZ) dark matter search experiment, on the applications of machine learning in physics data analysis, and on new photodetector development.

The group is led by Prof. Rick Gaitskell and is focused on experimental searches for dark matter. Brown is a major group in the world-leading LZ 8-tonne liquid xenon TPC direct detection experiment that is currently operating underground at Sanford Lab. Detector operations and follow-up data analysis are expected to extend into 2027.

The research will include dark matter search data analysis, nuclear recoil detector calibration techniques including the use of a deuterium-deuterium accelerator source, photodetector development for next-generation experiments, and also machine learning applied in a range of physics analyses. Previous experience with noble liquid detectors, direct dark matter search experiments, photodetectors, low-background techniques, data analysis, machine learning, or Monte Carlo simulations (GEANT4) will be advantageous. We are also looking at developing future small/fast satellite missions in particle astrophysics. There are no teaching responsibilities associated with this position.

Full details are available at should be submitted by December 1, 2023 for full considerationalthough review of applications will continue on a rolling basis until the position is filled. Any inquiries should be sent to . Submission is made online using

We are the Particle Astrophysics Group at Brown University. Our group consists of faculty, post docs, graduate students, and undergraduates conducting experimental work in direct dark matter detection.

Our group is currently involved in a research collaboration called LZ, a 10 tonne liquid xenon experiment almost 1 mile underground at the Sanford Underground Laboratory in South Dakota.

Congratulations to Will Taylor on completing his PhD thesis Neutron Calibrations and Activation Signals in Low-Background Liquid Xenon Dark Matter Detectors!
