The Participants

We are extremely grateful to the thousands of people who have taken part in our studies. Our wonderful participants have filled out questionnaires, attended clinics, and in some cases even let us take pieces of them away, such as blood samples and little pieces of muscle! Without our participants this research would simply not take place, and the knowledge we are gaining about health and disease may lay undiscovered.
