Dr. Tso received his Bachelor’s degree in Mechanical Engineering (First class), MPhil degree in Environmental Engineering and PhD degree in Mechanical Engineering from The Hong Kong University of Science and Technology (HKUST) in 2010, 2012 and 2015, respectively. He was awarded the Fulbright – Research Grant Council (RGC) Hong Kong Research Fellowship in 2014, and studied at the University of California, Berkeley (UC Berkeley) in 2015. After he came back from the UC Berkeley, he was a Research Associate at the Department of Mechanical and Aerospace Engineering (MAE), HKUST from 2015-2016, and promoted to the rank of Research Assistant Professor (2016-2018) before he joined CityU in Sep of 2018 as an Assistant Professor. He was also a Junior Fellow at the HKUST Jockey Club Institute for Advanced Study from 2016-2018 when he was at HKUST. Dr. Tso’s research interest covers thermofluid, heat transfer, energy and built environment, and energy efficient building technology, particularly, in the fields of adsorption technology, thermal diodes/switches, nanofluids/hybrid nanofluids, thermochromic smart windows and passive radiative cooling using numerical simulations as well as advanced experimental techniques. Dr. Tso is also active in entrepreneurship and technology transfer, and has been involved in setting up a start-up in 2012.

Dr. TSO focuses on understanding the fundamentals of heat transfer, energy conversion and engineered material science with the target of integrating theory and experiments to create innovative solutions to enhance thermal management, built environment, space cooling and refrigeration, micro-droplet manipulation and energy-efficient building technologies, making a great and global impact by addressing the biggest needs and issues in our world.
