Dr. Ruth Borghaei is a professor in the Department of Bio-Medical Sciences.

  • Education

    Dr. Borghaei  received her PhD in Microbiology and Immunology from Temple University School of Medicine in 1992 and her BS, (with highest distinction) in Microbiology from the University of Maine in 1987. She completed her postdoctoral studies at the Institute for Cancer Research of the Fox Chase Cancer Center in Philadelphia.

  • Courses

    Dr. Borghaei is director of the Molecular Basis of Medicine course in the Masters in Biomedical Sciences program and also teaches molecular biology and genetics to those students and to first-year DO students.

  • Research

    Dr. Borghaei's research interest is in transcriptional regulation of gene expression, particularly in response to inflammation. In addition, her lab is also interested in studying mechanisms behind epigenetic changes that occur in chronic inflammation, and may be involved in increased risk of carcinogenesis.
