Scholarly Activities:

My research interests lie in the field of developmental biology. The mechanisms by which a single cell can give rise to a complex organism have always amazed me. Cells must differentiate and signal to each other, turning on vast networks of genes while coordinating growth, shape, and function. Much research has been done on small range signaling molecules during development. During my graduate work, I became interested in molecules that signal over longer ranges: hormones.

My work has focused on the estrogen and androgen signaling pathways. These hormones are important in the developing embryo and in the adult vertebrate. These small molecules signal in many tissues of the body, including reproductive tissues, adipose, brain, bone, and heart. Both signal by binding to specific receptors. My work has involved characterizing the estrogen receptors, androgen receptors, and aromatase, the gene that codes for estrogen synthesis from testosterone. These genes are well conserved among vertebrates. Currently, the lab is focused on characterizing androgen receptors in zebrafish. The pleiotropic effects of hormones on gene expression could affect neural architecture resulting in morphological and behavioral effects well into adulthood.
