Greg Hermann

Professor of Biology

Biology-Psychology 226, MSC: 53

My goal as a teacher is to help my students become confident, creative, and critical thinkers. I believe that the way biology is taught and learned should reflect the way it is done. This means that I teach biology as a method for recognizing interesting phenomena, generating hypotheses, proposing experiments that test hypotheses, and critically evaluating data. Consequently, my courses emphasize the ideas, experiments, results, and reasoning that have led to a currently accepted model.

Undergraduate students in my research lab study organogenesis, the process by which a group of cells differentiate and associate to form an organ.  We are studying these processes during formation of the intestine in the soil nematode Caenorhabditis elegans. We have chosen this system for a number of reasons. First, the intestine of C. elegans is simple, consisting of only twenty cells, however the processes that occur during its formation are representative of processes that occur during the formation of more complex organs. Second, C. elegans is a an excellent system for the study of development; its entire embryonic cell lineage is known, its genome is sequenced, it is optically clear, it develops rapidly, and it is amenable to sophisticated genetic and molecular techniques.

Over the past 3 decades the field of developmental biology has undergone a striking transformation due to the application of modern cellular, biochemical, genetic, and molecular approaches, which has uncovered the mechanisms that specify cell fate. I am interested in how a group of cells that become specified to become part of a tissue or organ generates the cellular architecture that gives them their function. Studies in my lab address this question by focusing on the formation and differentiation of specialized cell-type specific compartments called lysosome related organelles (LROs). In humans, LROs carry out key functions within skin, lung, and blood cells. While much is known regarding the functions of LROs, for example pigment synthesis by melanosomes and blood clotting by platelet dense granules, the mechanisms involved in their construction remain poorly understood. Defects in these processes underlie a number of human genetic diseases. We are discovering and analyzing the function of genes controlling the formation of LROs in the model organism, Caenorhabditis elegans, whose homologues function similarly in humans.
