Daniel E. Park, Ph.D M.S.P.H., is an epidemiologist and research scientist. He received a Ph.D. in Epidemiology from George Washington University in 2023 and also holds an M.S.P.H. in Global Disease Epidemiology and Control from Johns Hopkins University.

Dr. Park's research has focused on antibiotic stewardship, microbiomics, vaccines, and pneumonia. His most recent work utilizes machine learning approaches and network analyses to elucidate mechanisms underlying associations between the human microbiome and risk factors for disease including COVID-19 and HIV. He co-developed novel Bayesian approaches to quantify zoonotic transmission of pathogenic bacteria, and co-leads antibiotic stewardship projects across a range of clinical settings. Prior work includes analysis of pneumococcal conjugate vaccine effects on upper respiratory tract carriage of pneumococcus, evaluation of digital auscultation in pediatric pneumonia diagnosis, and serving as lead coordinator and analyst for the Pneumonia Etiology Research for Child Health (PERCH) project. Dr. Park has collaborated with scientists and policy makers at the WHO, CDC, FDA, Children’s National Medical Center, and other agencies, organizations, and academic institutions, and has published over 50 peer-reviewed manuscripts including papers in The Lancet, Clinical Infectious Diseases, Biometrics, and Microbiome.
