Prof. HO Hung Chak Derrick (何鴻澤)

Hung Chak (Derrick) Ho is an Assistant Professor at Department of Public and International Affairs, City University of Hong Kong.

Derrick is a spatial demographer and a population health specialist with extensive experience in urban health. Derrick received his PhD from Simon Fraser University in 2016, and was trained as a research student (Section of Environmental Health Services) in the British Columbia Centre for Disease Control (BCCDC) between 2015 and 2016. He co-developed the government-based Heat Exposure Integrated Deprivation Index (HEIDI) with BCCDC for public health surveillance.

Derrick's expertise includes 1) spatial and environmental epidemiology, and 2) community health. His research focuses on social and environmental determinants of health, with particular interests in interactions between neighborhood deprivation, natural and built environment, healthy behaviors, and non-communicable diseases.

Derrick also works on non-pharmacological community health interventions to enhance pain management, livability and housing conditions, daily activities and physical/mental wellbeing among vulnerable subgroups. Additionally, Derrick has extensive experience in spatiotemporal analysis and remote sensing applications and machine learning modelling for population exposure and urban health assessment.

With his expertise, Derrick has published > 100 publications in prestigious journals, such as "Social Science and Medicine" and "Environmental Health Perspectives". Furthemore, Derrick serves as an Associate Editor for Annals of Epidemiology (Publisher: Elsevier), an Associate Editor for International Health (Publisher: Oxford), an editorial board member for BMC Public Health (Publisher: Springer), and an early career editorial board member for Environmental Research (Publisher: Elsevier). He is also a Global Assessor for Royal Society of Tropical Medicine and Hygiene.
