Research summary

Bio

Emre received the B.Sc. degree in electrical and electronics engineering from the Middle East Technical University (METU), Turkey in 2008 and the M.Sc. degree in electrical engineering from the Royal Institute of Technology (KTH), Sweden in 2010. Then, he worked as a part-time researcher in the Institute of Communication Systems and Data Processing (IND), RWTH Aachen, Germany. He joined the Department of Electrical Engineering (ESAT), KU Leuven, Belgium as a Ph.D. candidate in January 2011 and received the Ph.D. degree in May 2015. From July 2015 to May 2018, he was a postdoctoral researcher at the CLST group in Radboud University Nijmegen, Netherlands. He was a research fellow in the Department of Electrical and Computer Engineering at the National University of Singapore from June 2018 to March 2020. Currently, he is a senior computer scientist at the Speech Technology & Research (STAR) Lab in SRI International, CA, USA.
