Our Published Research
We conduct research with one goal: to provide robust evidence to better the health and well-being of the trans including gender diverse and non-binary community. This is our community. Every question we ask, every project that we do, every collaboration that we start must be aligned with our goal and translate to better health. Findings guide health and well-being programs, treatment guidelines and health policy to enable trans people to live a life without barriers.
