Cell Biology and Molecular Physiology

Visit the Cell Biology And Molecular Physiology homepage.

The Cell Biology and Molecular Physiology (CBMP) graduate program is made up of a dynamic group of investigators and students who use the modern-day tools of biochemistry, genetics, imaging, and molecular biology to understand the integrated biology and physiology of cells, organs, and whole animals. The faculty is drawn from both basic science and clinical departments and their research is focused on normal cellular biology and function, as well as understanding renal and heart disease, cancer and diabetes, as well as inherited disorders of developmental and reproductive functions. Further information about our program can be found at the Cell Biology And Molecular Physiology homepage.


CBMP students interact and work with an internationally recognized faculty, whose research is supported by grants from the National Institutes of Health and from other national research granting organizations. Faculty research includes study of normal cell biology and function, as well as a broad range of diseases that have a cell biological basis. Examples of their research interests include:

  • Cell Communication and Imaging
  • Cellular Injury and Wound Healing Chromatin, DNA Repair, Cell-Cyle Control, and Gene Expression
  • Ion Channel Biology
  • Membrane Traffic of Proteins and Lipids
  • Signal Transduction in Diabetes and Metabolism
