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 an applied geographer with expertise in health geography, spatial demography and community planning. His research focuses on linkages between the built environment and human health and well-being, with particular interest in relationships between social and environmental deprivations mediated by urban form and population health. Derrick has co-developed a “land developability index” project (www.landdevelopability.org) with the Population Research Institute at the Pennsylvania State University since 2013, and has participated in numerous studies for environmental health assessment, land use planning and spatial modelling. Derrick also co-developed the government-based Heat Exposure Integrated Deprivation Index (HEIDI) with the British Columbia Centre for Disease Control in Canada for public health surveillance, and served as the lead guest-editor of special issue for “Sustainability” in 2018 (Title: “Spatial and Spatio-Temporal Planning for Urban Health and Sustainability”). Derrick’s research has also been widely cited and reported in local newspapers and global media, including Ming Pao (HK), South China Morning Post (HK), the Guardian (UK), CBC (Canada), and Forbes (USA). He was interviewed for professional comments with the media, including Ming Pao (HK), the Guardian (UK) and BBC (UK).
Derrick is now expanding his research to support the vulnerable and marginalized population in Asian high-density cities. This includes to develop community planning protocols for the development of a “disabled-friendly environment” across the cities. The aim of this research is to apply a mixed-methods approach for the investigation of housing, social, and environmental health problems among the disabled population, with the hope to support this population through community design and health education in the coming future.
