Dr. Yang obtained his PhD from Caltech in 2013 and worked as a postdoctoral fellow in Perimeter Institute from 2013 to 2016 and in Princeton University from 2016 to 2017.  Starting from 2017 he joined the faculty of University of Guelph and became an associate faculty of the Perimeter Institute. Dr. Yang has worked on topics ranging from astrophysical sources for ground and space-based gravitational wave detections, Dark Matter searches, tests of General Relativity, strong-gravity phenomena, and advanced detector designs. Dr. Yang is the group lead of the Perimeter-Guelph-Waterloo group of the LISA Consortium and a member of the LIGO-Virgo Collaboration.In this talk I will discuss one of the primary targets of space-borne gravitational wave detectors – the Extreme Mass Ratio Inspirals, which usually comprises a massive black hole and a stellar-mass companion. In recent years there are significant progress in terms of its formation channel, rate estimation and dynamics in astrophysical environments. I will review these new developments and then discuss the significance of detecting these sources with gravitational waves and possibly electromagnetic counterparts.
