Andrew Koff, PhD

My laboratory has combined biochemical, molecular, cellular, and genetic approaches to investigate the roles of CDK inhibitors in differentiation, development, and cancer biology. An additional major focus of the laboratory is directed towards understanding how these gene products are regulated to accomplish these roles.

Andrew Koff, PhD

  • Molecular biologist Andrew Koff is interested in identifying the genes and and molecular mechanisms by which cells make decisions regarding their proliferative capacity after they exit from the cell cycle during therapy induced senescence and during normal development.
