Timothy Rodwell, MD, PhD, MPH

Associate Professor


Dr. Rodwell’s research is primarily focused on tuberculosis (TB) with an emphasis on the molecular epidemiology of drug resistance and development and implementation of rapid molecular diagnostics for TB and acute febrile syndromes. He is currently leading a large multinational study to develop and field test a novel, table-top platform for clinical diagnosis of XDR-TB (R01AI111435), and is Project Director of a CFAR study to demonstrate that quantifiable, phenotypic drug resistance to fluoroquinolone antibiotics can be reliably predicted by rapidly detectable mutations in Mycobacterium tuberculosis (Mtb). He is also a co-investigator on several NIH funded studies examining the functional significance of novel mutations in drug resistant Mtb genomes (R01AI105185), developing a point-of-care platforms for rapidly detecting drug-resistant strains of Tuberculosis (R44EB011274, R44 GM103053) and a clinical trial to demonstrate the effectiveness of mobile phone-based TB therapy monitoring (U01 AI116392).
