Dr. Don Thushara Galbadage is an associate professor of Applied Health Sciences at Texas Christian University (TCU) specializing in microbiology, epidemiology, neurodegenerative diseases and C. elegans. His research focuses on antimicrobial resistance, the gut-brain axis in Parkinson’s disease, and the role of gut microbiota in neuroinflammation. Using C. elegans as a model, he investigates microbial and metal toxicity influences on neurodegeneration and oncogenesis.

Dr. Galbadage holds a Ph.D. in Medical Sciences from Texas A&M University and an M.P.H. in Epidemiology from the University of Texas. His work has contributed to cutting-edge therapeutic approaches, including molecular nanomachines targeting multidrug-resistant pathogens. He collaborates across disciplines to bridge microbiology and neuroscience and is strongly committed to mentoring future scientists. His high-impact publications include studies on antimicrobial resistance mechanisms, nanomedicine-based therapies for infectious diseases and determinants of health leading to disparities in COVID-19 spread.
