Eliana Marino is an immunologist with a large experience in medical research. She started her undergraduate studies at Simon Bolivar University and moved to Australia in 2004, where she was awarded the NHMRC-Dora Lush Biomedical Postgraduate Research Scholarship. Dr. Mariño PhD studies focused on the characterization of antigen-presenting B cells and their control on Treg and CD8+ T cell activation that drive autoimmunity in T1D (Mariño, Diabetes, 2008,2009, 2012). Dr. Mariño’s research focuses on nutritional immunology, microbiome-derived natural products with a particular interest in enhancing our understanding of host immunity. Her research program has fundamentally shifted our understanding of the role of diet, gut microbiome, and the immune system in the development of type 1 diabetes (T1D), spurring new research directions worldwide and bringing diet-based therapeutic options one step closer by advancing this basic research to clinical trials. Her work’s seminal findings have significantly contributed to the field of microbiome, medicine, gut infection, kidney disease, asthma, microbiome-brain axis and autoimmunity by tracing the role of short-chain fatty acids (SCFAs). Nowadays, her work is expanding to other fields such as periodontal disease, obesity and cancer.
