Short Biography

My name is Ganzhao Yuan. I was born in a small village in Dongguan City, Guangdong Province, China. I earned my Ph.D. in School of Computer Science and Engineering at South China University of Technology. Previously, I worked as a postdoc researcher in School of Mathematics at South China University of Technology, and in Visual Computing Center at King Abdullah University of Science and Technology. I also worked as a Research Associate Professor in School of Data and Computer Science in Sun Yat-sen University. Currently, I am an Associate Researcher in Peng Cheng Laboratory. My research interests mainly center around mathmatical optimization (e.g., semidefinite optimization, discrete optimization, nonconvex optimization) and its applications (e.g., in machine learning, quantum computing, computer vision).
