Research
The main focus of my research is to study how the fusion of a sperm and egg initiates the program of development, how activation of the genetic information that is stored in the egg is used during the early stages of development to form the basic cells and tissues in the adult.

The egg itself is a very highly specialized cell, containing the proteins or informational molecules required to begin this program of development. These proteins and informational molecules are stored in the egg in an inactive state. Fertilization triggers their activation and the onset of development. My basic research deals with identifying these informational molecules and the events at fertilization which trigger their activation.
