Mark H. Kaplan

Mark H. Kaplan, PhD

Chair, Department of Microbiology & Immunology


Professor Kaplan received an Honours B.Sc. from the University of Windsor in 1987 (Biology) and a PhD. from Wayne State University in 1992 (Immunology and Microbiology). He did postdoctoral work at the University of Texas Southwestern Medical Center and at the Harvard University School of Public Health. He joined the Faculty in the Indiana University School of Medicine in 1998 as an Assistant Professor of Microbiology and Immunology. In 2005, he moved to the Department of Pediatrics to become the Director of Pediatric Pulmonary Basic Research. In 2008, he was promoted to Professor and in 2014 was honored with the Billie Lou Wood Professorship. In 2017, Dr. Kaplan was named as Associate Director of the HB Wells Center for Pediatric Research.

Professor Kaplan’s work is focused on understanding the function of transcription factors in the development of T helper cell subsets. He has a long standing interest in Signal Transducer and Activator of Transcription or STAT proteins that are activated downstream of cytokines. His more recent work has made great progress towards understanding the development and function of IL-9-secreting T cells in the development of allergic inflammation. His interests lie in understanding how T cell subsets contribute to allergic and autoimmune inflammation.

Professor Kaplan has been on the Editorial Boards of the Journal of Immunology and JAK-STAT and is currently  Senior Editor for the new American Association of Immunologists journal ImmunoHorizons. He has served on and chaired numerous study sections for grant application to the National Institutes of Health, and other private and international review panels. He has served on the IUSM Biomedical Research Committee for over ten years and is currently the co-chair. He is also the Director of the NIH-funded T32 Training Program in Immunology and Infectious Diseases.
