Research Program:

Research in my lab focuses on the following: 1) molecular and physiological mechanisms of sperm motility initiation during fertilization; 2) molecular pathways leading to cell specification and embryonic axis determination, and; 3) effect of environmental pollutants- both natural and anthropogenic-on these critical stages of animal development. We use a number of experimental systems for these studies, including gametes and early embryos of sea urchins, herring and zebra fish, as well as cultured embryonic mouse fibroblast cells. Much of these studies is collaborative and involves scientists from University of California Davis, University of Hawaii and the University of Tokyo. One of the current research projects involves investigations into the effects of specific polycyclic aromatic hydrocarbons (PAH) on axis determination in sea urchin and zebra fish embryos. Our recent studies indicate that PAHs, some of which are known to be potent environmental carcinogens, disrupt axis development in sea urchin embryos via the beta-catenin dependent molecular pathway. Studies are underway to determine the specific molecular targets for PAHs.
