We are studying genes that regulate growth and reproduction in mammals and fish.
My laboratory uses the tools of molecular and cellular biology to study growth and reproduction in mammals and fish. We are working to identify and isolate genes that are directly involved in growth in mammals based on biochemical properties, tissue-specific expression, and chromosomal location. In fish, we are studying the genetics of polyploids and interspecific hybrids as well as genes involved in reproduction. We are working on both vitellogenin synthesis in the liver as well as receptor mediated uptake of the egg yolk proteins by the oocytes. Egg production in fish and poultry has potential application as an animal bioreactor system.
