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 Dongqing Huang on being formally awarded your PhD from Brown. We look forward to continuing to work with you on LZ.
