Prof. Jean-Didier Legat received his engineering and PhD degrees in microelectronics from the Université catholique de Louvain, Louvain-la-Neuve, Belgium in 1981 and 1987, respectively. From 1987 to 1990, he was with Image Recognition Integrated Systems (I.R.I.S.), a new company specialised in optical character recognition and automatic document processing. Jean-Didier Legat was co-founder and Vice-President of I.R.I.S.

 In October 1990, he came back to the UCL Microelectronics Laboratory. He is presently full Professor. From 2003 to 2008, he was the Dean of the Louvain School of Engineering and, from 2015 to 2021, he was the Head of the ICTEAM Research Institute. 

His current interests are processor architecture, low-power digital integrated circuit, real-time embedded systems, mixed-signal design and hardware-software codesign for reconfigurable systems. He has been an author or co-author of more than 200 publications in the field of microelectronics, low-power digital circuits, computer architecture, digital signal processing, computer vision and pattern recognition. He is a senior member of the IEEE.
