Biography

Dr. Amine Bermak received both his MEng and PhD degrees in Electronic Engineering from Paul Sabatier University, France in 1994 and 1998, respectively. During his PhD, Dr. Bermak was part of the Microsystems and Microstructures Research Group at the French National Research Center LAAS-CNRS where he developed a 3D VLSI chip for artificial neural network classification and detection applications. He joined the Advanced Computer Architecture research group at York University, England, where he was working as a Post-doc on VLSI implementation of CMM neural network for vision applications in a project funded by British Aerospace. In November 1998, Dr. Bermak joined Edith Cowan University, Perth, Australia, first as a research fellow working on smart vision sensors, then as a lecturer and a senior lecturer in the school of Engineering and Mathematics. He is currently an Associate Professor with the Electronic and Computer Engineering Department of Hong Kong University of Science and Technology (HKUST), where he is also serving as the associate director of Computer Engineering. He is also the founder and the leader of the Smart Sensory Integrated Systems Research Lab at HKUST.

Dr. Bermak has been very actively involved in many industrial projects in collaboration with Motorola-France, 3D plus- France, British Aerospace-UK, Intelligent Pixel Inc-USA. His research interests are related to VLSI circuits and systems for signal, image processing, sensors and microsystems applications. Together with his research team, Dr. Bermak proposed several novel VLSI architectures and designed a number of prototype chips for various applications including: (i) a world-first 3D VLSI chip for classification applications, (ii) high dynamic range CMOS image sensor based on time-domain encoding and featuring programmable resolution and conversion time (iii) ultra low-power operating technique for current mediated CMOS image sensor; (iv) a number of smart vision micro-sensors, in which both the imager and the signal processor were integrated on the same VLSI chip, such as histogram equalization, image compression and image segmentation; (v) VLSI implementation of biologically inspired shunting inhibition processing for edge detection and image enhancement; (vi) monolithically integrated gas sensor array with on-chip pre-processing circuitry (vii) novel algorithmic solutions (such as Gaussian Mixture models, bagging decision trees) for gas discrimination and electronic nose applications and their hardware friendly implementation.

Dr. Bermak has received many distinguished awards, including the 2004 “IEEE Chester Sall Award” from IEEE Consumer electronics society; the “Best Paper Award” at the 2005 International Workshop on System-On-Chip for Real-Time Applications and the “Bechtel Foundation Engineering Teaching Excellence Award" from the school of Engineering HKUST in 2004. Dr. Bermak is a member of technical program committees of a number of international conferences including the IEEE Custom Integrated Circuit Conference CICC’2006, CICC’2007, the IEEE Consumer Electronics Conference CEC’2007, Design Automation and Test in Europe DATE2007, DATE2008. He was the invited keynote speaker at the 5th IEEE International Workshop on System on Chip for Real-Time Systems, IWSOC05, Banff, Alberta, Canada, July 2005. Dr. Bermak has published more than 120 articles in journals, book chapters and conference proceedings and designed over 15 VLSI chips. He is a Senior Member of IEEE and a member of the IEEE CAS committee on sensory systems. He is on the editorial board of IEEE Transactions on Very Large Scale Integration (VLSI) Systems and IEEE Transactions on Biomedical Circuits and Systems.
