Accelerator based atomic, molecular and optical (AMO) physics studying simple cryogenic gases, cryogenic films, liquid helium, and doped solids; laboratory astrophysics using CRDS, laser studies of doped rare-earth crystals.
Present Research and Outreach Activities
I retired in 2008 and am no longer advising graduate students. My activities with the Guelph Observatory are ongoing. The transit of Venus in 2012 was broadcast to a large lecture hall at the university and to the Civic Museum in downtown Guelph. It drew about 500 participants many of whom also looked at the sun through a filtered Questar telescope. Each spring I have been giving two lectures to high school students as part of Guelph Interaction, and, in some years, a lecture and star party for Guelph Alumni. I taught two courses in fall 2009 and a two week special topics module in February 2010, one course in fall 2011 and one in fall 2013. My long awaited (by me at least!) textbook, The Fundamentals of Atomic and Molecular Physics, was published by Springer in 2013.
