Join a Study

For participants

RxPix Study

This is a study comparing new and different ways of measuring medication adherence. Medication adherence is one’s ability to take their medications the way their doctor prescribed them and without missing any doses. By measuring medication adherence, we can see how effective HIV medications are.

With your help, we can learn how to make HIV meds work better for everyone.

For service providers

Center of Excellence for Transgender Health

After two years of work focused on HIV prevention in California, the Center of Excellence is expanding the scope of breadth of our work. We are now the Center of Excellence for Transgender Health. Our expanded mission builds on our strengths in capacity building, formative research, training, and community mobilization. In addition to the many resources on our website, we offer FREE trainings and consultations in Spanish and in English:

  • Professional intermediate-level and advanced-level trainings that we create, implement, and evaluate are tailored to your specific organizational and health provider needs. These trainings may range in length from 2 hours to 2 days.
  • Consultations or technical assistance to enhance programming, build capacity, and better conduct effective research and interventions are offered for health professionals serving trans people throughout California. Our consultations may be conducted in person, by phone, or by email.


The MPowerment Project is currently being replicated across the U.S. Please visit the MPowerment website to learn more about the most appropriate materials and services for your organization.


The Transitions Project provides capacity building and technical assistance to community-based organizations and health departments throughout the U.S. to promote knowledgeable, sensitive, and effective HIV/AIDS prevention for transgender communities of color and HIV+ transgender people.
