Dr. Falk received the BSc degree from the Federal University of Pernambuco, Brazil, in 2002, and the MSc and PhD degrees from Queen’s University, Canada, in 2005 and 2008, respectively, all in electrical engineering. In 2007, he was a visiting Research Fellow at the Sound and Image Processing Lab, Royal Institute of Technology (KTH), Sweden, and in 2008 at the Quality and Usability Lab, Deutsche Telekom/TU Berlin, Germany. From 2009-2010 he was an NSERC Postdoctoral Fellow at Holland-Bloorview Kids Rehabilitation Hospital, affiliated with the University of Toronto. Since 2010, he has been an Assistant Professor at the Institut National de la Recherche Scientifique (INRS) in Montreal, Canada. Dr. Falk is also an Adjunct Scientist at Holland-Bloorview and a Research Advisor for InteraXon – Thought Controlled Technologies in Toronto.
