- Research:
- My research is focused on understanding the mechanisms that regulate growth factor induced changes in the adhesive and migratory behaviors of cells in early vertebrate development. Embryos of the African clawed frog, Xenopus laevis, are used together with biochemical, molecular and immunological techniques to investigate the involvement of Rho family GTPases in mesodermal and cranial neural crest cell migration.
Another area of current interest is the role of nitric oxide synthase and nitric oxide signaling in the regulation of neuroanatomical changes associated with metamorphosis in the marine mud snail, Ilyanassa obsoleta. This work is part of an ongoing collaboration here at UNCG with Dr. Esther Leise. - Recent Publications:
