Professor Coffman received his B.S. in 1986 from Iowa State University. In 1993 he received his Ph.D. from U.C. San Diego, where his mentors were William A. Harris and Christopher R. Kintner. He was a postdoctoral research fellow at Boulder CO from 1993 – 1997, where his mentor was Robert E. Boswell. Professor Coffman joined the faculty of Iowa State University in 1998 as an Adjunct Assistant Professor of Zoology and Genetics and continued that appointment in the Department of Genetics, Development, and Cell Biology, where he became an Assistant Professor in 2004 and then Associate Professor in 2011.
My laboratory studies the regulatory networks governing cell migration and programmed cell death with the goals of better understanding how these processes contribute to metastatic cancer states and how they help shape the embryo during development. We use the germ cells of Drosophila melanogaster as a model. During development, the germ cells of this fruit fly actively invade and cross an epithelial layer, move over and through multiple types of mesoderm, and then colonize a distant site, the embryonic gonad. These migratory movements and the ability to colonize secondary locations are extremely analogous to metastatic cancer cells which leave the primary tumor and move to other locations. Careful regulation of programmed cell death is another common feature of developing germ cells and metastatic cells. In the case of developing germ cells, cells that reach the gonads survive while those outside of the gonads execute a cell death program. Metastatic cells must thwart a myriad of death signals in order to establish secondary tumors. We are using forward and reverse genetic approaches, plus the tools of molecular, cellular, and developmental biology to elucidate the signaling networks mediating these fundamental biological processes.
