S. Randal Voss, Ph.D.

Associate Professor, Biology Department

Director, Ambystoma Genetic Stock Center
Director, Salamander Genome Project
Area of Graduate Study: Genetics, Genomics, Evolution, Development.

Research Interests

Dr. Voss's research interests are in regenerative biology using a salamander model (Mexican axolotl). Salamanders are unparalleled in their ability to regenerate complex body parts, including spinal cord and limb. Dr. Voss's lab is using genomic and bioinformatic approaches to identify genes that are expressed differently between salamanders and mammalian models that show little or no functional response after injury. The goal is to build systems-level models that reveal how to induce a natural regenerative response. Dr. Voss is also using salamanders to identify quantitative trait loci for regeneration and metamorphic traits, and investigate vertebrate genome evolution.
