Chang Gao - Assistant Professor @ TU Delft

My name is Chang Gao (高唱). I am an Assistant Professor at the Department of Microeletronics, TU Delft. Currently I am a Postdoctoral Researcher in the Sensors Group at the Institute of Neuroinformatics (INI), University of Zurich and ETH Zurich. I am designing energy-efficient AI hardware (FPGAs & ASICs) and software optimization methods for the training and inference of deep neural networks (DNNs). I am leading the Lab of Efficient circuits & systems for Machine Intelligence (EMI), TU Delft
