  • Biography
    Aquaculture is the fastest growing food-producing industry in the world with an average annual growth rate of 8.7% per year, three times higher than the growth rates observed for terrestrial farm meat production. Moreover, expansion in aquaculture offers perhaps the greatest potential to meet the growing demand for food worldwide. Based upon current projections for world population growth, current levels of aquatic food consumption and food security issues in developing nations, aquaculture production is expected to grow by 40M metric tons by 2030 nearly doubling current production at 51.7M metric tons.

  • Research Projects
     My research focuses on two areas of aquaculture: 1) Improved understanding of molecular genomic mechanisms involved in metabolism and physiology such as carbohydrate utilization among salmonids and 2) development of novel molecular genomic methods to detect disease or differentiate hatchery and wild populations.

    In addition to research, my laboratory carries out applied molecular genetic training of students and scholars at all scholastic levels from high school to visiting professors from other universities. At present, my lab has trained over 100 students and scholars in molecular genetic/genomic techniques at the aquaculture Research Institute and the Hagerman Fish Culture Experiment Station. I am committed to providing STEM (Science, Technology, Engineering and Mathematics) opportunities and experience to high school students and teachers who participate in laboratory activities with me throughout the year.  My laboratory also works closely with fish farmers and state/federal hatcheries providing outreach and applied research to promote and enhance the growing aquaculture industry in Idaho. Currently we are working with farmers in Southern Idaho to develop methods to detect the sex of white sturgeon at an earlier age and the use of ultrasound to develop non-invasive methods to check the egg maturity of sturgeon females.
    I also teach UI summer courses which include fish genetics and applied statistical methods.My research focuses on two areas of aquaculture: 1) Improved understanding of molecular genomic mechanisms involved in metabolism and physiology such as carbohydrate utilization among salmonids and 2) development of novel molecular genomic methods to detect disease or differentiate hatchery and wild populations.
