Research & Publications
Dr. Ethel Weld is an internist-pediatrician specializing in clinical pharmacology and infectious diseases. She is strongly committed to patient-oriented clinical investigation within academic medicine. Her current research program and long-term career goals within clinical research include contributing to the existing body of knowledge about clinical pharmacologic aspects of the prevention and treatment of HIV and treatment of multidrug-resistant tuberculosis. Her strong interest is in the development of novel drug delivery strategies that are broadly acceptable, less toxic to patients, implementable for programs and do not require daily pills, including nanoformulated, parenteral, long-acting antiretrovirals and microbicides. She is also interested in seeking treatment and prevention strategies that are behaviorally congruent and do not require patients to deviate significantly from existing behaviors. Dr. Weld is interested in such strategies primarily as a method to optimize adherence to treatment and preventive regimens, as adherence is the well-documented Achilles’ heel of any prevention or treatment intervention.
