Dr. Sameer S. Kadri is currently an associate research physician and head of the Clinical Epidemiology Section in the Clinical Center's Critical Care Medicine Department.
MD, Seth G.S. Medical College
MS, Harvard School of Public Health
Dr. Kadri earned his degree in Medicine from the Seth G. S. Medical College and King Edward Memorial Hospital in Mumbai, India. He trained in Internal Medicine at the New York-Presbyterian/Weill Cornell Medical Center, Infectious Diseases at the Massachusetts General Hospital, in Critical Care at the NIH Clinical Center and in Clinical Epidemiology at the Harvard T.H. Chan School of Public Health.
Dr. Kadri was recently awarded tenure and appointed to Senior Investigator in 2026 in the NIH Clinical Center's Critical Care Medicine Department at the NIH Clinical Center. In this role, he splits his time between attending in the ICU, serving as an NIH principal investigator, supervising a data Lab, and training fellows. Prior to this he held positions of Staff Clinician (2014-2021) and Tenure Track Investigator (2021-2026) within the same department.
His primary research interest lies in identifying clinical and public health strategies to improve patient outcomes in acute illness through real world evidence. He leverages large clinical and administrative datasets to generate insights through innovative epidemiologic investigations on a diverse array of high mortality conditions. These include therapeutically challenging conditions such as antimicrobial resistant infections and sepsis and operationally challenging conditions such as hospital overcrowding in public health emergencies and everyday care to inform clinical care and health policy. Dr Kadri's lab has contributed several landmark investigations to help improve care delivery and outcomes in disasters and public health emergencies that helped enable large-scale operational changes in patient management during the pandemic. This includes studies showcasing the detrimental impact of hospital overcrowding, the safety in moving patients with respiratory failure between hospitals, and the impact of centralizing transfer coordination on transfer rates.
He founded and leads the NIH Antimicrobial Resistance Outcomes Research Initiative (NIH–ARORI), an interagency and extramural collaborative. He developed and tested a novel classification scheme for antimicrobial resistance called "Difficult-to-treat Resistance" or DTR that focuses on non-susceptibility to all first-line antibiotics. His group has performed studies comparing the real-world effectiveness of antibiotics used to treat infections for which clinical trials and unfeasible and unlikely. His lab collaborates closely with other federal agencies and several University-based investigators. Dr. Kadri has been awarded several NIH intramural grants including RASCL and Director's Challenge grants and received non-NIH grant funding. He has won several research, mentorship, and early investigator awards and other accolades from professional societies for his work.
Dr. Kadri has authored over 135 peer-reviewed publications and has held various editorial positions over the years. He has mentored several clinician scientists who have gone on to secure independent funding and prestigious academic positions. He has served on several scientific review committees, technical expert panels, and on CDC and National Academies of Sciences, Engineering and Medicine-led initiatives.
