Department of Physics and Astronomy
Douglas Welch received his PhD from the University of Toronto in 1985. He engaged in postdoctoral work at the National Research Council's Herzberg Institute of Astrophysics' Dominion Astrophysical Observatory in Victoria, BC as a Research Associate before joining the faculty at McMaster in September 1988 as a NSERC University Research Fellow. He was Chair of the Department of Physics and Astronomy at McMaster between July 1997 and May 2000.
The current research interests of Dr. Welch include the extragalactic distance scale, dark matter studies using microlensing and variable stars. His work with the MACHO Project has involved the analysis and characterization of pulsating variable stars. He has been a Co-I on several successful HST proposals and is a frequent user of offshore national facilities. He is part of the "Next Generation Microlensing Survey" (a.k.a. "SuperMACHO") began taking data in the 2001/2002 LMC observing season and is scheduled to continue for five years.
To date, he has supervised four Ph.D. and four M.Sc. students.
Dr. Welch is currently the Canadian Gemini Scientist.
