Siva Sivoththaman

Dr. Siva Sivoththaman is a Professor in the Department of Electrical and Computer Engineering at the University of Waterloo.

Dr. Sivoththaman earned his Doctorate from the University of Paris XII - Créteil Val de Marne (France) in 1993. He then worked as a Research Scientist at the Interuniversity Microelectronics Centre (IMEC) in Belgium for six years before relocating to Canada in 2000 to join the Department of Electrical and Computer Engineering at the University of Waterloo.

Dr. Sivoththaman has held 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.

Dr. Sivoththaman served as the inaugural Director of the University of Waterloo's Nanotechnology Engineering Program (2004-2006), the Associate Chair of Graduate Studies in the Department of Electrical and Computer Engineering (2008-2012), and the Associate Dean of Graduate Studies & Postdoctoral Affairs in the Faculty of Engineering (2019-2025). He is a Senior Member of the IEEE.
