Siva Sivoththaman is a Professor in the Department of Electrical and Computer Engineering and Associate Dean, Graduate Studies & Postdoctoral Affairs in the Faculty of Engineering.

Professor Sivoththaman received the Doctorate from University of Paris XII - Creteil Val de Marne (France) in 1993. He then worked as a Research Scientist at the Interuniversity Micro Electronic Center - IMEC (Belgium) for six years before moving to Canada in year 2000 to join the Department of Electrical and Computer Engineering at the University of Waterloo. Professor Sivoththaman was a recipient of the Ontario Premier's Research Excellence Award in 2002 and has held two Research Chairs, the NSERC Associate Industrial Research Chair in Radio Frequency Micro Electro Mechanical Systems (2002-2006), and the Ontario Research Chair (ORC) in Renewable Energy Technologies and Health (2010-2015). He is also the Director of the Centre for Advanced Photovoltaic and Display Systems (CAPDS) at Waterloo. Professor Sivoththaman served as the inaugural director of University of Waterloo's Nanotechnology Engineering Program during 2004-2006. He is a Senior Member of the IEEE and currently serves as Chapter Chair for the Electron Devices Society of the IEEE Kitchener-Waterloo section.
