Dr. Ortiz is a Professor of Medicine at the UMSOM. He trained as an adult pulmonary and critical care physician and has additional training in field epidemiology and vaccinology. He is an internationally recognized expert in respiratory virus prevention and control. He began his public health research career in 2005 as an Epidemic Intelligence Service (EIS) Officer in the Influenza Division at the US Centers for Disease Control and Prevention (CDC). In this position, he led outbreak investigations for avian influenza in West Africa, designed the global respiratory virus (SARI) surveillance system, and conducted influenza clinical epidemiologic research. After leaving the CDC in 2007, he became faculty at the University of Washington where he led an influenza research group and collaborated on influenza vaccine trials in Senegal, South Africa, and Bangladesh. He was seconded to the World Health Organization (WHO) in Geneva to provide clinical expertise during the 2009 H1N1 influenza pandemic. From 2014-2017, he was a Medical Officer at the WHO Initiative for Vaccine Research where he led influenza vaccine policy, implementation, and research activities. His portfolio also included adult immunization, maternal immunization, and clinical RSV disease. At WHO, he was a member of the Editorial Board for Immunization Position Papers, helping to develop and update institutional policy for numerous vaccines.
Since 2018, he has worked as a physician scientist at the Center for Vaccine Development and Global Health at the University of Maryland. He was the site-Principal Investigator on the Adaptive Covid-19 Treatment Trial (ACTT-1), the first clinical trial to identify an efficacious COVID-19 treatment. He was also a coinvestigator on clinical trials for Moderna and Pfizer COVID-19 vaccines. He is the Co-PI on the NIH-funded Collaborative Influenza Vaccine Innovation Centers (CIVICs) Clinical Core at UMSOM, and he leads CIVICs studies developing controlled human influenza virus infection models to accelerate clinical development of influenza vaccines. He is an advisor to the Council of Medical Specialty Societies on adult immunization, and he co-chairs the American Thoracic Society Vaccine Initiative which aims to improve adult immunization rates among persons with chronic lung disease in the United States.
