Dr. Mark Shegelski
Professor of Physics

Mark Shegelski was previously Assistant Professor at the University of Lethbridge, Department of Physics. Previous academic posts have also included teaching and research at Dalhousie University, and research as a Visiting Scientist at the University of New South Wales in Australia.
He gained his PhD in theoretical condensed matter physics from the University of British Columbia, MSc in theoretical physics from the University of British Columbia, and a BSc First Class Honours in astrophysics from the University of Calgary.
Current research interests include quantum mechanical tunneling and decay, and the motion of sliding, rotating cylinders.
