Research Interests

Hepatocellular carcinoma; Biliary tract malignancies, as well as carcinoma of unknown primary site; Gastrointestinal malignancies


Dr. Cosgrove aims to identify molecular biomarkers in cancer cells that can differentiate them from normal cells. These differences at the genetic and molecular level should allow us to develop drugs that will target only the cancer cells, and have minimal side effects on the patients normal cells. He is working closely with the gastrointestinal malignancies group to bring new drugs and combinations into clinical practice. The ultimate goal is to identify the best drug, or combination of drugs, for individual patients based upon their tumors genetic makeup. The same approach should also allow us to identify drugs that will not be effective against particular tumors, so ineffective therapy can be avoided.

    Research Summary

    Dr. Cosgroves research is focused on molecular changes in tumor cells, specifically within proliferation pathways such as MAPK and PISK/AKT. He is developing agents to target these pathways, and biomarkers to identify patients most likely to benefit from such agents.
