Tanguy Seiwert, MD

Assistant Professor of Medicine

Dr. Tanguy Seiwert is a specialist in head and neck cancer as well as lung cancer. Dr. Seiwert has a special interest in developing improved treatment strategies for these diseases. He looks for new ways to combine traditional treatments, such as chemotherapy and radiotherapy, with the latest targeted agents, in order to improve treatment results and decrease side effects.

Dr. Seiwert's research focuses on the biology of head and neck cancer and lung cancer. In the laboratory, he studies targeted therapies that disrupt specific pathways vital to cancer growth and metastasis. He studies which novel drugs appear most promising, which individual tumors are more likely to respond to these treatments, and how to successfully combine therapies. Dr. Seiwert uses this pre-clinical knowledge to develop new treatments for use in clinical trials, and to ultimately improve patient care.
