Mark A. Lemmon, Ph.D. is the David A. Sackler Professor of Pharmacology, and Co-Director of the Cancer Biology Institute at Yale University. He has just moved to Yale after 19 years at the University of Pennsylvania Perelman School of Medicine, where he was the George W. Raiziss Professor and Chair of Biochemistry and Biophysics and an Investigator in the Abramson Family Cancer Research Institute. Dr. Lemmon received his B.A. (Hons, First Class) in Biochemistry from the University of Oxford (Hertford College), England in 1988, and then moved to Yale for his Ph.D., which he did with Donald M. Engelman in the Department of Molecular Biophysics and Biochemistry as an HHMI Predoctoral Fellow. In 1993, he moved to Yossi Schlessinger’s lab at New York University Medical Center (Pharmacology) in Manhattan, as Marion Abbe Fellow of the Damon Runyon Cancer Research Foundation, prior to moving to Penn in 1996 as Assistant Professor in the Department of Biochemistry and Biophysics (and Johnson Foundation). Dr. Lemmon’s laboratory ranges from mechanistic, structural, and biochemical to cellular and clinical aspects of signaling by growth factor receptor tyrosine kinases such as EGF receptor family members and ALK. He is also an expert in phosphoinositide signaling. His lab has been responsible for much of our current understanding of extracellular regulation of the EGFR. At Penn, he was promoted to Associate Professor in 2001, to full Professor in 2004, and was appointed Chair of Biochemistry and Biophysics in 2010. Dr. Lemmon serves on the Editorial Boards of several prestigious journals, including Cell and Molecular Cell, and is Deputy Chair of the Biochemical Journal Editorial Board as well as its Vice-Chair for the Americas. He also serves on the external advisory board of cancer research programs at MIT, Dana Farber, Kings College London, the University of New Mexico, and the Ontario Institute for Cancer Research, and on the Scientific Advisory Board of Kolltan Inc. Dr. Lemmon was also Secretary of ASBMB from 2007 to 2013. His awards include Penn Medicine’s Stanley N. Cohen Research Award in 2009 and the Protein Society’s Dorothy Crowfoot Hodgkin Award in 2012.
