“A precious jade pearl descended to the world, becoming the enchanting scenery of West Lake; dark matter traverses through the Earth, pushing new discoveries in science.”

Biography

Shengchao Li graduated from the University of Hong Kong in 2013 with a Bachelor's degree in Physics, and earned a Master's degree in Particle Physics from the same university in 2015. In 2020, he earned a Ph.D. in Physics from Virginia Tech in the United States, where he continued to research as a postdoctoral associate at Purdue University. In August 2023, he joined Westlake University as an assistant professor, with research interests focused on the experimental detection of dark matter and neutrinos.

Research

Dr. Shengchao Li works on the Daya Bay Neutrino Experiment, the CHANDLER Neutrino Experiment, the XENON1T/nT Dark Matter Experiment, and the Windchime Dark Matter Experiment. His research focuses on the development of experimental systems and innovative technologies related to neutrinos and dark matter, to explore new physics beyond the standard model of particle physics. His related research has achieved the following pioneering results:

1.    Using ton-scale dual-phase liquid xenon detectors to explore a vast spectrum of dark matter models (e.g., WIMPs), broadening the horizon of the dark matter search by overcoming key limitations, probing new theoretical models. Detector calibration R&Ds towards the next-generation experiment.


2.    Fully utilizing the development of quantum sensing technology, develop pathfinders for an innovative large-scale accelerometer array, equipped with quantum devices at the standard quantum limit, to provide a new path for the exploration of dark matter via gravitational interaction alone.


3.    Developed innovative near-reactor plastic scintillator neutrino detectors, utilized a neutron beam for energy calibration. Successfully measured the reactor neutrino spectrum in a surface-level environment, towards the test of sterile neutrino hypothesis and reactor monitoring applications.


4.    Using liquid scintillator detectors to analyze and reconstruct neutrino inverse beta decay signals at different baselines, and to characterize the background induced by cosmic rays. The experiment provided a precise measurements of neutrino oscillation parameters and reactor neutrino spectra, while providing a deeper understanding of nuclear reactions related to neutrinos.
