  • Biography
    Projects in Dr. Cloud's research program are primarily directed toward understanding germ cell development in salmonids and the establishment of a germplasm repository for threatened and endangered fish. Ongoing research projects in the lab include the cryopreservation and transplantation of salmonid gonads and the isolation, culture, and reestablishment of germinal stem cells. Additionally, sperm collected from numerous populations of Snake River chinook salmon and steelhead are cryopreserved and stored annually. The work in Dr. Cloud's lab is currently funded by the USDA and BPA.

    Dr. Cloud completed postdoctoral work at Johns Hopkins University and has had a sabbatical leave with Dr. E.F. Graham, who was a world-leading cryobiologist at the University of Minnesota. He has also received the Gamma Sigma Delta and the ASUI Outstanding Faculty Award for teaching excellence.

    Dr. Cloud also advises students interested in pre-nursing studies.
