Molecular & Dev. Bio: R Christenson

Developmental Biology: Randy Christensen

Research opportunities with Dr. Christensen lie in the areas of molecular genetics and developmental biology. Dr. Christensen’s lab uses gene expression analysis – including confocal laser-scanning fluorescent microscopy – to analyze molecules involved in wound healing and regeneration. Dr. Christensen’s research students regularly sequence novel genes in salamanders, examine their gene expression, and publish sequence information in GenBank at the National Center for Biotechnology Information. Students also engage in an intensive analysis of the molecules involved in cell-cell communication following injury. For example, excitatory neurotransmitter molecules can be released at toxic levels after injury, affecting nearby nervous system cells in a process known as excitotoxicity. Knowing more about the molecular changes that occur in nervous system cells after injury may someday enhance human recovery from spinal cord injury or traumatic brain injury.
