Professor, Physics and Astronomy, McMaster University
"I have been a member of the AAVSO since I was a teenager - which was a LONG time ago - have served on AAVSO Council for three terms and was the third Janet A. Mattei Visiting Fellow in July 2010. My AAVSO-related activities in recent years include being a co-investigator on APASS and creating and maintaining an epoch-photometry database available to AAVSO members. My current research interests and activities include studying supernova light echoes as well as classical Cepheids, Type 2 Cepheids and RR Lyrae stars."
