Michael Eck
Principal Investigator
Longwood Center, LC 4313
Michael_Eck (at) dfci.harvard.edu
eck (at) crystal.harvard.edu
Dr. Eck received his M.D. and Ph.D. in Biochemistry from the University of Texas Southwestern Medical School. He completed his Postdoctoral training under Dr. Stephen Harrison in Structural Biology at the Boston Children's Hospital and the Harvard Medical School before joining DFCI in 1996. Dr. Eck is currently a Professor of Biological Chemistry and Molecular Pharmacology at the Dana-Farber Cancer Institute and Harvard Medical School. His research focuses on the structure and regulation of tyrosine kinases in cancer and on structure-based approaches to discovery of novel inhibitors. The Eck lab also studies the structure of formin proteins and their role in assembling the actin cytoskeleton.
