I have been interested in the origins of novelty and innovation in organisms (primarily vertebrates) and how changes in the genome can facilitate molecular and organismal adaptation in the long term, and the onset of disease in the short term. My laboratory uses whatever tools are necessary to address fundamental biological questions. This includes large-insert cloning, comparative genomics, computational biology, molecular genetics, imaging, biochemistry, and developmental biology. We often employ "deep branches" in vertebrate phylogeny as they allow us to study the origin of characters germane to higher vertebrates, and they provide very good vantage points for making comparisons with other organisms for deducing the genetic basis of biological innovations, such as limbs, lungs, and adaptive immune systems. A common thread in my laboratory's research is the use of comparative genomics methods for deducing genomic features that may be important for emergence of novelty. I have been involved in genomics from my early career as a postdoctoral fellow with the Human Genome Project, and I developed early PAC and BAC libraries of the zebrafish (which were critical for physical mapping and positional cloning of many developmental genes. We have used zebrafish experimentally for many years in order to verify our molecular analyses and to validate our inferences. My lab continues to work in areas germane to evolution and development of cellular structures and morphologies. I am a new faculty member at UC Merced (started in Fall 2017) and was brought on as a senior member. My new roles include research mentorship of junior faculty and contributing to the growth of a new research university. I am also the newest Chair of the Quantitative & Systems Biology program at UC Merced.
