Research Assistant Professor

Dr Kevin Ka-Lun Lau is Research Assistant Professor at Institute of Future Cities, The Chinese University of Hong Kong. His primary research interest is on the relationship between the built environment and urban climate, with a particular focus on human thermal comfort in outdoor environment. His research ranges from numerical modelling of urban microclimate to field studies of outdoor thermal comfort, with over 50 articles published in peer-reviewed journals. He is a member of the WMO Expert Network of the Commission for Observation, Infrastructure and Information Systems and the Commission for Weather, Climate, Water and Related Environmental Services and Applications.

 

Dr Lau is also affiliated with CUHK Jockey Club Institute of Ageing where he collaborates with public health experts on the inter-relationships between the built environment, urban climate and the health of citizens. He is experienced in translation research which transfers scientific knowledge into practical guidance in climate-sensitive urban planning and design. He is currently working on a collaborative project on increasing the resilience of elderly population to the impacts of extreme hot weather in the future, which focuses on enhancing weather information services, mitigation strategies through neighbourhood and building design, and awareness and preparedness of elderly population through community services. He is also leading an international study of developing a global database for outdoor thermal comfort studies and establishing a standardised methodology for conducting outdoor thermal comfort surveys under the IAUC working group of outdoor thermal comfort.

Research Assistant Professor

Yu Zhou received the B.Sc., M.Sc., and Ph.D. degrees from Nanjing University, Xiangtan University, and The Chinese University of Hong Kong, China, in computational mathematics, applied mathematics, and geography and resource management, respectively. He was a post-doctoral fellow at The Chinese University of Hong Kong, Hong Kong, China working on multifractal approach to multiscale feature extraction in remotely sensed images, and post-doctoral guest scientist at the Max Planck Institute for the Physics of Complex Systems, Dresden, Germany on nonlinear time series analysis. He is currently a Research Assistant Professor of the Institute of Future Cities at The Chinese University of Hong Kong.  He has been trying to introduce multidisciplinary concepts and ideas into geography for teaching and research. Most of his research in theory originates from real life problems in geographical studies. After the new theories or methods developed for solving the theoretical problems, he applies them to study the empirical data for demonstration of their validation.
