As a Research Data Analyst with the Pulmonary Division at San Francisco General Hospital, I work with Dr. Adithya Cattamanchi on research studies to improve the diagnosis and treatment of patients with tuberculosis (TB). I coordinate clinical data collection, management, and analysis for the multi-country R2D2 TB Network study to evaluate novel TB diagnostics and the DOT to DAT Trial, evaluating use of digital adherence technology for TB treatment in Uganda.
