Professor Thomas’ research is focused on the study of the biology and clinical use of human dendritic cells in autoimmune disease. It has explored basic mechanisms of immunity and dendritic cell function in autoimmune disease.
Professor Thomas is a graduate of the University of Western Australia. She received her MBBS in 1984, and then trained in Perth as a rheumatologist. She commenced a research fellowship with Peter Lipsky at Southwestern Medical Center, University of Texas in 1990, where she first identified and characterised human circulating dendritic cell precursors. For more than 10 years in studying the function of dendritic cells in autoimmune diseases, she has written many articles, including several hypothetical articles on the immuno-pathogenesis of rheumatoid arthritis. She was appointed as Senior Lecturer at The University of Queensland in 1994, and promoted to Professor in 2004. Ranjeny is founder and a director of the spin-off company, Dendright, which is developing vaccines to suppress autoimmune diseases.
