Dacheng Lin

Dacheng Lin joined UNH as a research scientist in February 2014 and became a research assistant professor with a joint appointment in the Department of Physics and at the Space Science Center of the Institute for the Study of Earth, Oceans, and Space (EOS) in 2017. Before joining UNH, he was a post-doctoral researcher at the University of Alabama for 1.5 years and at IRAP, France for 3 years. He graduated from Massachusetts Institute of Technology with a PhD in Physics in 2009, and did his undergraduate education at the University of Science and Technology of China.

The main research interest of Dr. Lin includes:

  • The accretion process around black holes across mass scale: black-hole X-ray binaries, ultra-luminous X-ray sources, AGN
  • Tidal disruption events (Tidal disruption of stars by otherwise dormant supermassive black holes)
  • Search for intermediate-mass black holes of mass 100--100,000 solar mass
  • Catalog studies
  • The accretion process in neutron-star low-mass X-ray binaries and properties of dense matter
