Biography
Qingsha S. Cheng
Qingsha (Shasha) Cheng received the B.Eng. and M.Eng. degrees in automation from Chongqing University, China, and the Ph.D. degree from McMaster University, Canada, in 2004. He is currently an associate professor at Southern University of Science and Technology in Shenzhen, China.
His research focuses on space mapping, surrogate modeling, simulator-based tuning, computer-aided design, and fast modeling and optimization methods for microwave circuits, antennas, and RF systems.
Academic Path
He worked with Peking University in 1998 and joined the Simulation Optimization Systems Research Laboratory at McMaster University in 1999, later serving as a postdoctoral fellow, research associate, research engineer, and sessional lecturer.
SUSTech Appointment
He joined SUSTech in 2014 as an assistant professor and later became a tenured associate professor. He was appointed Adjunct Professor with the University of Regina, Canada, in 2018.
Professional Service
He has served as an associate editor of the International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, and has reviewed for major microwave and antenna journals.
Conference Activity
He has organized or chaired workshops and sessions for SMSMEO, IEEE IMS, IEEE NEMO, IEEE ICCS, IEEE ACES, IEEE ICCEM, and ACES-China, including electromagnetic modeling and optimization activities for IEEE MTT-S Young Professionals.
One of the original contributors to the Space Mapping algorithm, with more than 25 years of research experience and more than 5800 Google Scholar citations as of April 2026.
