Education and Training

Dr Lydia Tangobtained her medical degree from the University of Wales College of Medicine, Cardiff, United Kingdom, and bachelor's degree in Science in Pharmacology at Kings' College, London, United Kingdom. After graduation, she completed her Pre-Registration House Officer postgraduate training in medicine at University Hospital Llandough and surgery at Singleton Hospital, Swansea, United Kingdom, before working as a Senior House Officer in emergency medicine at Hillingdon Hospital, London. She completed Internal Medicine Residency at Orlando Health, Orlando, FL, holding the position of Chief Resident, and Fellowship in Infectious Diseases at the University of Maryland Medical Center. Dr. Tang has been a member of the academic faculty at the Institute of Human Virology, University of Maryland School of Medicine, since 2012.


My research interests are focused on host-pathogen interactions and host correlates with disease clearance in chronic hepatitis B and C infections, with and without HIV infection. I joined Dr Shyam Kottilil’s translational research group after graduating from ID fellowship where I am an investigator on multiple studies exploring the role of innate and adaptive immunity in the pathogenesis of these diseases. I am the principal investigator for the HOPE study, a natural history study of patients with hepatitis B, C and HIV; TEMUL (TEnofovir alafenaMide for HBV – a longitUdinaL study), a treatment study where patients are treated with tenofovir alafenamide, a nucleos(t)ide analogue; and MAVERIC (MAraViroc EfficacyfoR HepatItis C), a study aimed at exploring the role of CCR5 antagonism in the pathogenesis of liver fibrosis in patients with HIV with and without HCV infection.

Research/Clinical Keywords
