Josephine Pui-Hing Wong has extensive experience in critical public health and urban health, including the development of public health access and equity policy and practice frameworks, and large-scale health communication campaigns. She collaborates with marginalized communities to develop, implement and evaluate capacity-building health promotion and collective empowerment programs. Josephine’s program of research is underpinned by the principles of social justice and equity. She is committed to doing research “with” and not “for” the affected communities. She seeks to answer the “so what” and “what then” questions in all her research. Being mindful of the need and urgency to go beyond understanding specific phenomena about health inequities, she works closely with the affected communities to develop socially innovative solutions that promote collective resilience and social change. Her areas of research include: social identities and health practices; HIV, sexual health, and mental health in diasporic and transnational communities. She has led and is leading numerous intervention studies on stigma reduction and mental health promotion in the Asian, Black and Latino communities in Canada as well as among university students in China. Currently, she is leading a rapid response research to mitigate the negative impacts of the COVID19 pandemic.
