In 1989, Dr. Krämer completed his Ph.D. at the University of Cologne, Germany, where he worked with Dr. Benno Mülller-Hill on DNA looping in the lac operon. As a postdoctoral fellow in the lab of Dr. Larry Zipursky at UCLA, he studied cell-cell interactions during neuronal differentiation in the compound eye of Drosophila. In 1993, he joined UT Southwestern Medical Center at Dallas as an Assistant Professor in Cell Biology and Neuroscience.
