Biography
Dr. Arasaratnam graduated from the University of Oxford Medical School with honors (2006) and completed his internal medicine residency in England (2011). He subsequently moved to the United States to pursue further internal medicine training at the University of North Carolina (2013) and Infectious Disease Fellowship at Baylor College of Medicine (2017) with a focus on care of the immunocompromised patient. During his clinical training he obtained a Master in Public Health from the Harvard T.H. Chan School of Public Health (2008) and pursued additional research in translational viral immunology, resulting in one of the first prospective multi-virus characterizations of T cell immunity in a pediatric solid organ transplant cohort, and another study identifying dominant T cell targets of Parainfluenza virus 3 (PIV-3).
Dr. Arasaratnam joined the UT Southwestern faculty in 2017, predominantly focusing on infectious disease care of the immunocompromised patient. In 2020, he was appointed as the Assistant to the Medical Services Chief for Education at the Dallas VA Medical Center. In this role, he is supporting and growing the current educational activities of this training facility while providing comprehensive inpatient and outpatient infectious disease care for veterans and Attending on Internal Medicine Teaching Service.
Dr. Arasaratnam is double board certified in Internal Medicine and Infectious Disease through the American Board of Internal Medicine (ABIM) and is also a Member of the Royal College of Physicians (MCRP), United Kingdom. On a national level, he also serves on the Infectious Diseases Item-Writing Task Force for the ABIM and the American College of Rheumatology Clinical Guidance Task Force on COVID-19 vaccination.
His clinical interests include infectious disease care of the immunocompromised host, viral infections, vaccination and non-tuberculous mycobacterial (NTM) infections. As a medical educator, Dr. Arasaratnam has a strong focus on teaching and assessing clinical reasoning, faculty development and fostering an inclusive clinical learning environment for the trainee.
