Dr. Tso received his Bachelor’s degree in Mechanical Engineering with 1st class honors, 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. During the period from Nov. 2014 to May 2015, Dr. Tso exchanged at the University of California, Berkeley as a Fulbright Visiting Research Scholar. From Sep. 2015 to Aug. 2016, he served as Research Associate at the Department of Mechanical and Aerospace Engineering (MAE), HKUST. From Sep. 2016 to Aug. 2018, he served as Research Assistant Professor at the MAE, HKUST and a Junior Fellow at the HKUST Jockey Club Institute for Advanced Study.

Dr. Tso joined the City University of Hong Kong as Assistant Professor in the School of Energy and Environment in Sep 2018. His research interest covers thermofluid, energy conversion in a built environment, particularly, in the fields of heat transfer, adsorption technology, thermal rectification, nanofluids, smart windows and passive radiative cooling using numerical simulations as well as advanced experimental techniques.

In early 2018, Dr. Tso has established a Massive Open Online Course (MOOC) named Introduction to Indoor Air Quality with Prof. Christopher Y.H. Chao (Dean of Engineering and Chair Professor of Mechanical Engineering, The University of Hong Kong) on Coursera. Besides, Dr. Tso is also active in entrepreneurship and technology transfer, and has obtained more than 5 patents and has been involved in setting up a start-up in 2012.
