A research participant is someone who participates in a research study. Research involving human participants (often referred to as 'subjects') may take place in many places in and around the community. The majority of GHUCCTS-related research will take place in the Washington, DC metro area at participating universities and hospitals. If you are considering participating in a research study, remember that participation is completely voluntary you can choose not to participate, or, if you do decide to participate, you can choose to stop participating at any time.
