Research Synopsis

Dr. Burchell uses epidemiological data to improve prevention and health care services for sexually transmitted infections (STIs) and minimize the complications of STI-associated diseases. STIs are a major health concern. They can result in compromised sexual/reproductive health, cancers, stigma, worsened quality of life, and mortality. Disadvantaged people are disproportionately affected and may face health access barriers that further concentrate STIs within high-risk networks and amplify transmission. Dr. Burchell’s vision is to end these complications and promote sexual health for all, with aims to inform effective and practical strategies to prevent STI and STI-related cancers in high-risk populations.
