Trevor Moraes, PhD

Associate Professor

Bacterial cell surface membrane proteins provide accessible targets for small molecule inhibitors, and also provide surface accessible epitopes that can serve as antigens in the implementation of vaccines against pathogens—thus an understanding of their structure and function provides useful insights into the development of new therapeutics against bacterial pathogens. Dr. Moraes’ research focuses on understanding the mechanisms of outer membrane proteins that function in nutrient transport across the Gram negative bacterial cell envelop. Dr. Moraes will continue to use this information to develop vaccines based on engineering these surface proteins into antigens that can protect against invasive disease.
