Associate Professor, Dr. Bridgett vonHoldt [CV], trying to teach her nieces about wolf watching.
Stephen will be joining our group, joint with Prof Andrea Graham, this fall as a post-doctoral scholar working on gene regulation and immunity in bottlenecked populations. We look forward to welcoming him!
I am fascinated by the diversity of questions that can be addressed with molecular techniques within the fields of conservation biology and evolutionary ecology. Through use of genetic, epigenetic, and microbial sequencing technologies, I am currently applying an integrative molecular approach to the study of wildlife populations facing disease. I additionally study the genetic effects of urban colonization and range expansion, with prior experience in method development for noninvasive genetic monitoring of carnivore species. My focal systems include North American wolves, coyotes, and foxes, but I am broadly interested in the application of these techniques to questions involving diverse taxa around the world. For more, please visit my website.
My main area of research is in comparative genomics. I have always been interested in the way that genomic variation contributes to phenotypic diversity and the underlying mechanisms responsible. More specifically, I am interested in understanding the role that transposable elements play in generating standing genetic variation that can then be selected within different selection regimes. By incorporating high-throughput sequencing technologies along with machine learning algorithms, we can better understand how genomes evolve. In the vonHoldt lab, I'm exploring the genetic and epigenetic response of deer mice (Peromyscus maniculatus) to stress induced by hypoxia and am constantly studying dog genomics.
I am a first year graduate student and am broadly interested in understanding genetic basis of complex and variable phenotypes such as behavior. I am especially intrigued by behaviors of evolutionary significance in animals, including sociability and mating behaviors.
