Alex Toker is a Professor in the Department of Pathology at Beth Israel Deaconess Medical Center, Harvard Medical School, Chief of the Division of Signal Transduction and Associate Director of the Cancer Research Institute in the Cancer Center. The lab has membership in the Biological and Biomedical Sciences PhD Program, the Dana-Farber/Harvard Cancer Center, and the Ludwig Center at Harvard.
Our research focuses on the cell and molecular biology of cancer. We are investigating the mechanisms by which signaling pathways impact tumor cell survival, invasion and metastasis. We are also studying metabolic alterations in tumor cells and how these lead to vulnerabilities that can be used to target tumors with specific therapies. Our goal is to decipher the complex mechanisms by which these pathways impact cancer progression, with the ultimate goal of developing drugs that interfere with malignancy.
We welcome inquiries from graduate students and postdocs. We are seeking highly motivated, collaborative trainees with an interest in studying the regulation and effects of oncogenic signaling in cancer. If you are a graduate student, please email Alex about your research interests. If you are seeking a postdoc position, please email us with your CV, three reference contacts, and research interests.
