William W. Cruikshank, PhD
Professor of Medicine

Boston University School of Medicine


  • College Education: Washington and Jefferson College, B.S. 1977
  • Graduate School/PhD Program: Boston University, Ph.D. in Biochemistry 1988.


Dr. Cruikshank received his doctorate degree in Biochemistry in 1989 from Boston University School of Medicine, in Boston Massachusetts.  During the past 37 years his research focused on the biology of CD4 as it relates to its natural ligand, Interleukin-16.  Dr. Cruikshank, along with Dr. David Center, discovered IL-16 in 1980.   They have well over 150 papers describing IL-16 as it relates to the sequence, tertiary structure, interaction with CD4, intracellular signaling events, cellular responses, as well as IL-16’s presence and function at sites of inflammation.  As a pulmonary immunologist Dr. Cruikshank’s research has primarily focused on inflammation associated with the initiation and perpetuation of an asthmatic response.  Dr. Cruikshank has now shifted his focus to tuberculosis and taken a position with Oxford Immunotec as Director, Scientific Affairs.
