Estelle Bettelli, PhD
Dr. Bettelli received her BS in Cellular Biology from the University Pierre et Marie Currie (Paris 6) in 1995 and her PhD in Hematology/Immunology from the University Denis Diderot (Paris 7) in 2001. Following a postdoctoral fellowship and after serving as an Instructor in the Department of Neurology at the Brigham and Women’s Hospital, Boston, she served as an Assistant Professor at Harvard Medical School. Dr. Bettelli joined the faculty of the Benaroya Research Institute as an Assistant Member in 2009. She is also an Affiliate Assistant Professor in the Department of Immunology at the University of Washington School of Medicine.
Areas of Research
Research in Dr. Bettelli's laboratory is focused on understanding the development, regulation and functions of the adaptive immune system in cancer and autoimmune diseases such as multiple sclerosis. In particular, she is studying how to modulate and control a population of leukocytes called T helper 17 (Th17) cells, which are believed to be highly pathogenic in autoimmunity and could play an important role in cancer.
