My laboratory studies the basic principles of animal development. In particular, we are interested to understand how hormonal and other signaling processes regulate and coordinate development, growth and metabolism. We use a model organism, the little fruit fly Drosophila melanogaster, to study developmental processes at an organismal level using an array of genetic and molecular tools that is unique for this organism. Since the basic mechanisms underlying development are conserved between flies and vertebrates including humans, we hope that the results of our research will be of general significance.

I teach an upper level class in Developmental Biology and contribute to the teaching of our core course in General Genetics.
