Dr. Yan received her B.Sc. and M.Sc. degrees from Xi’an Jiaotong University in China and Ph.D. degree from the University of Strathclyde in Glasgow, UK. She was a research scientist at Ryerson University in Toronto prior to joining the University of British Columbia Okanagan in July 2008.

Dr. Yan is an active researcher and educator in the field of thermofluids and energy. She has successfully conducted projects funded by the Canadian Space Agency, NSERC, EPSRC (UK) and various industry partners. Her projects include CFD analysis for diffusion/thermodiffusion (also called Soret effect or thermophoresis) under reduced gravity conditions; vapour-liquid equilibrium in multicomponent fluid mixtures; heat transfer and two-phase flow of HFC mixtures in refrigeration systems; and optimization for turbomachines. Dr. Yan has received many awards along her academic career including the prestigious Ted Perry Memorial Award by the Institute of Refrigeration in the UK.
