Dear Volunteers,

Due to the heightened awareness and worldwide concern about the spread of the novel coronavirus (COVID-19), Duke University School of Medicine has paused research activities on campus. In an effort to reduce the risk of faculty, staff, students, and visitors, our team has decided that it is in our best interest to work remotely from home.

We sincerely appreciate all of your engagement and interest on our website page. However, we are currently postponing any recruitment efforts for our research trials until a future date. If you have already signed up for our recruitment registry, your information is on file and our research team will reach out to you when enrollment for our studies resume.

Thank you again for your interest and help to grow our scientific community.

Clinical Trials

Led by William (Bill) Kraus, MD, the Kraus Research Group located on the Duke Center for Living campus in Durham, North Carolina has over 20 years of experience conducting clinical trials in humans. With expertise in preventive cardiology, rheumatology, exercise science, nutrition, immune function, energy balance and mobile health technologies, our diverse team of experts studies how the body works with a focus on improving the prevention and treatment of diseases. To support our ongoing research efforts we are actively recruiting participants for a variety of studies. We are looking for healthy volunteers as well as individuals who may have certain disease conditions such as diabetes, heart disease, peripheral arterial disease (PAD), and arthritis. We invite you to view the fliers on this site for a list of our current studies.
