Peter Mascher obtained a Ph.D. in Engineering Physics in 1984 from the Graz University of Technology (TUG) in Austria and joined McMaster University in 1989 in a position initially funded by the Ontario Centre for Materials Research. He is a professional engineer and a professor in the Department of Engineering Physics, was Chair of the Department from 1995 to 2001, and since 2003 serves as the Associate Dean (Research and External Relations) of the Faculty of Engineering, with responsibilities for coordinating major research initiatives and collaborations of the Faculty. From 2012 to 2013, Dr. Mascher served as Acting Associate Vice-President, International Affairs, overseeing McMaster’s International Portfolio. He currently is a member of the governing body of organizations as diverse as the Green Auto Power Train Initiative, several APC and ORF projects, the University Network of Excellence in Nuclear Engineering, and Nano Ontario. Dr. Mascher holds the William Sinclair Chair in Optoelectronics and leads active research groups involved in the fabrication and characterization of thin films for optoelectronic applications, the development and application of silicon-based nanostructures, and the characterization of defects in solids by positron annihilation spectroscopy. Since 2010, he leads a collaborative initiative to transform the McMaster Nuclear Reactor into one of the world’s brightest positron sources for applied and fundamental research. Dr. Mascher has supervised more than 40 Ph.D. and master’s degree students, has authored or coauthored more than 200 publications in refereed journals and conference proceedings, and has presented many invited lectures at international conferences and workshops. In 2012, he was inducted as a Fellow of the Canadian Academy of Engineering.
