Special Interests

Research Interests

Dr. Kern is an expert in how cells in the lung grow, focusing on a family of proteins that regulate cell growth by transmitting signals outside the cell to the inside. These proteins play an important role in keeping a cell’s growth in check. When these proteins malfunction, abnormal growth ensues which can result in lung cancer. Dr. Kern’s research tries to understand how these protein signals are regulated, discover molecules that interfere with this process and might be used as chemotherapy, and discover new proteins regulating cell growth.
