Dr. Gareth Brady
Ussher Assistant Professor, Clinical Medicine


My research career to date has been consistently focused on a strategy of using viruses to understand host immunity since I began post-graduate research, completing a PhD in 2005 on the investigation of novel immunoregulatory sequences in the genome of Vaccinia Virus with Professor Luke O'Neill (TCD). I then accepted a six month industrial placement in Opsona Therapeutics leading an independent project to establish several assays and reagents for screening anti-inflammatory compounds partially based on viral strategies of immune evasion and returned to academia.

In late 2006, I began a post-doctoral Leukemia and Lymphoma Research (LLRF) fellowship in the Section of Virology, Imperial College London with Professor Paul Farrell analyzing mechanisms of genetic cross-regulation during Epstein Barr Virus (EBV) immune evasion and discovered a complex regulatory control pathway manipulated by the virus to control Runx1 and Runx3 gene expression.

On completion of my EBV research, I wished to pursue a long-standing interest to begin research on the only known human-adapted poxvirus Molluscum Contagiosum Virus (MCV) which, despite the fact that the virus appeared incredibly adept at silencing local immunity and inflammation to go largely unnoticed during long term infections, had remained largely unexplored. To pursue this, I returned to Ireland on a Marie Curie career development IEF fellowship under the mentorship of Professor Andrew Bowie in Trinity College Dublin.

I became an Ussher Assistant Professor of Vascular Biology in Trinity College Dublin in 2017 and am continuing my research on inflammation signalling and my group is developing novel anti-inflammatory compounds using autoimmune vasculitis as a model for their activity. Additionally, my recent research involves developing seroassay tools for SARS-CoV2 and understanding both the immune response to this virus in COVID-19 and how the virus evades this response.

Research Expertise


My interests are centered on Viral Immune Evasion, understanding novel aspects of inflammatory signalling and Innate Immunity an the development of Novel anti-inflammatory therapeutics. My research Group the Translational Inflammation Research Group (TIRG) which currently consists of 4 PhD students, two post-doctoral researchers (one currently being hired) a research assistant and a 5-month Spanish Erasmus student. Our SFI-Frontiers funded research focuses on understanding how the human-adapted poxvirus Molluscum Contagiosum Virus evades human immunity and the therapeutic potential of peptides derived from the virus. Our Allergan and SFI-funded COVID research is focused on developing seroassay tools for SARS-CoV to monitor pre- and post-vaccination immune responses in the population in addition to understanding how the virus is detected by and evades the immune system. Our Vasculitis UK funded research focuses on understanding the innate immune signalling of autoantibody-stimulated inflammation in monocytes in an ANCA vasculitis model of disease.
