Biography
Xin Qian is a particle physics scientist working to answer some of the remaining questions in the standard model of particle physics and to search for new physics beyond the standard model. Xin obtained his Ph.D. in experimental nuclear physics from Duke University. He then joined Caltech as Robert Millikan Post-doctoral Scholar studying neutrinos. After the post-doc training, Xin joined Brookhaven National Laboratory as staff scientist and was promoted through the rank. He is currently physicist with Distinction of Tenure and adjunct associate professor at Stony Brook University. Xin has been working on numerous particle physics experiments as well as detector technologies from both hardware and software sides. Xin has won many awards including 2011 Jefferson Laboratory Thesis award, 2014 DOE early career award, 2017 EPS Young Experimental Scientist Prize for his contribution to the Daya Bay experiment, 2022 BNL Science and Technology Award (the highest honor at BNL) for his contribution to the MicroBooNE experiment and the development of LArTPC detector technology.

Research Statement
My physics interest lies on answering some of the remaining questions about neutrinos: i) are there new CP violations in the neutrino sector? ii) what is the nature of non-zero neutrino mass and mixing? and iii) are there new flavors of neutrino? I have been spending most of my time working on the development of the Liquid Argon Time Projection Chamber (LArTPC), which is a new and powerful detector technology to study accelerator neutrinos. Together with my colleagues, we came up with a new way of performing event reconstruction in LArTPC: Wire-Cell. This technique is expected to be crucial for upcoming LArTPC experiments: SBN and DUNE.


Recently, I am working to develop a new rare pion decay experiments: PIONEER, to test lepton flavor universality and CKM unitarity. See SNOWMASS white paper.


Prior working on particle physics, I worked on electron scattering experiments in understanding the spin structure of nucleon at Jefferson Lab.
