Trans Health Research

Research Overview

We are a diverse, highly productive research group established in 2017 in response to community need and additionally provide a large clinical service to the trans and gender diverse (TGD) community. Our research group’s purpose is for TGD people to live a life without barriers; to go about daily life being safe, healthy and well. All our research projects are community-focussed, guided by and with TGD staff to guide best treatments and drive health and well-being programs to better the community. We currently have a number of projects underway that span from understanding gender-affirming treatments, health professional education in trans health, best models of clinical service delivery to reducing stigma and discrimination. We want all our research translated into improving health and well-being outcomes in the community and cannot do this without collaborating widely and valuable community support. We want to ensure that TGD voices are heard; directing their health needs and research priorities.
