Kathleen Martin, Ph.D.

Assistant Professor of Surgery and Pharmacology and Toxicology
Research Description: Understanding the molecular mechanisms, especially signal transduction to cell type-specific transcription factors, that regulate vascular and uterine smooth muscle cell phenotype, proliferation, and differentiation, which are central to processes including atherosclerosis, intimal hyperplasia, restenosis and labor initiation.

Raymond P. Perez, M.D.

Associate Professor of Medicine and of Pharmacology and Toxicology, and Associate Director for Clinical Research, Norris Cotton Cancer Center
Research Description: Clinical pharmacology and early trials of anticancer agents, particularly molecular targeted therapies; Mechanism of action and proof-of-principle for novel drugs and combinations; Modulation of signal transduction and cell death, particularly focused on endogenous inhibitors of receptor-kinase mediated signaling and downstream determinants of sensitivity to apoptosis.

David J. Robbins, Ph.D.

Associate Professor of Pharmacology and Toxicology
Research Description: The Hedgehog (Hh) signal transduction pathway plays a critical role in both embryonic development and in cancer, through mechanisms that are poorly understood. My research program is focused on elucidating the role Hh plays in human disease. This goal is approached in two ways: 1) elucidating the production and presentation of the secreted ligand Hh and 2) dissecting the signaling pathway downstream of the Hh receptor. We study this signaling pathway in both developmental and pathological settings, making our research highly complementary and mutually supporting. Such an approach will more rapidly decipher the mechanism by which the Hh pathway contributes to human disease.
