We are interested in understanding the development of endocrine networks in fish and how early-life experiences can influence the function of these networks in the adult fish.
Specific projects include:
1. Cell-cell communication and its control of migration of GnRH neurons.
2. Thyroid axis function during larval development of fish.
3. Epigenetic programming of the thyroid axis through early-life experiences.
4. Central control (hypothalamus, pituitary) of the thyroid axis in fish.
5. Thyroid control of fish growth.
Our main methods include molecular biology, a variety of physiologcal methods, the generation and use of transgenic fish (tilapia and zebrafish) and live imaging.
