About the Investigator

Dr. Kim Simpfendorfer completed her undergraduate degrees and PhD at the University of Melbourne in the Department of Microbiology and Immunology, in Melbourne Australia. Her PhD studies focused on the mucosal immune system and particularly on the presence of antibodies that function to protect the body’s mucosal surfaces. She also studied secreted mucosal antibodies in the context of interactions between the environment and the development of autoimmune diseases such as Type 1 Diabetes.

Kim joined the Robert S. Boas Center for Genomics and Human genetics in 2010 as a Postdoctoral Fellow to work with Dr. Peter K. Gregersen on the functional genetics of human autoimmunity. Kim served as the Secretary of the Young Investigators Society at the Feinstein Institute from August 2014 until September 2015.

Research Focus

Since joining Dr Peter Gregersen’s group at The Feinstein Institute for Medical Research, Kim’s research has focused on the functional analysis of immune-related genes associated with lupus and rheumatoid arthritis.
