Preferred method of communication

I am currently seeking 1 MSc student and 1 BSc summer student to join my research group in 2020. The MSc candidate is expected to have a solid background in fluid dynamics and/or numerical methods; familiarity with or strong interest in data science and machine learning would be a plus. The BSc summer student is encouraged to apply for the NSERC USRA and the UofC PURE awards (https://research.ucalgary.ca/students) to secure financial support; please email me with your CV and unofficial transcript if you are interested – I will let you know if I see a fit and will help you with your award applications.

Research activities

Environmental fluid mechanics

Dr. Zhou’s research uses numerical, analytical and experimental tools to study the movement of water in natural and engineered systems, such as oceans, estuaries, lakes and reservoirs. The environmental quality of these systems depends critically on the fluid flows through and within them, and understanding the fluid mechanics of these flows is crucial for an engineer whose goal is to describe or predict the influences of these physical processes on the environment, for example, how turbulent mixing which occurs at a very small scale could affect the overall distribution of heat, nutrients and pollutants within the bodies of natural waters. 

In his research, Dr. Zhou performs cutting-edge computer simulations of flow processes of interest at parameter values as close as possible to those encountered in the environment. High-performance parallel computing is routinely used for these simulations, and state-of-the-art data analytics tools are leveraged to interpret various flow phenomena and extract dynamical insights from the big data generated by massive simulations. Dr. Zhou’s research aims at developing simple yet robust models which are capable of predicting the impact of climate change and other human influences on Canada’s most precious water resources. The research is inherently interdisciplinary and involves interactions with fluid dynamicists, oceanographers, applied mathematicians and computer scientists.


Biography

Dr. Qi Zhou has been an assistant professor in the Department of Civil Engineering since 2017, following two years at the University of Cambridge in the UK where he worked as a postdoctoral researcher. Dr. Zhou completed his PhD thesis on internal waves and stratified turbulence at Cornell University in Ithaca, New York, in 2015. Before moving to the East Coast in 2010, he studied at Stanford University in California and at Nanyang Technological University in Singapore.
