Ho, Derrick H. C.

B.S.(Tntech); M.S.(Msstate); PhD(SFU)

Hung Chak Ho (Derrick Ho) is a Research Assistant Professor in the Department of Urban Planning and Design at The University of Hong Kong. Derrick received his PhD from Simon Fraser University, 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.

Derrick’s research focuses on urban resilience and environmental hazards, with particular interests in spatiotemporal modelling and machine learning applications for environmental exposure and health assessments. He co-developed the government-based Heat Exposure Integrated Deprivation Index (HEIDI) with BCCDC for disaster risk planning and public health surveillance. Derrick is now expanding his research to support the vulnerable and marginalized population in Asian high-density cities. This includes to develop protocols for the development of resilient and healthy cities” across East Asia. The aim of this research is to apply a mixed-methods approach for the investigation of social and environmental health problems among the marginalized people, with the hope to support this population through community design and health education in the coming future.
