Research Abstract
My laboratory has been using Hydra as a model system to investigate questions in developmental and evolutionary biology since I joined the UC Irvine faculty in 1986. In 1989, my lab published the first paper describing the cloning of a Hydra protein-coding gene. I was the corresponding author on the Hydra genome paper that was published in Nature in 2010. Hydra is well known for its regenerative powers, its robust patterning system, and its lack of senescence. We are using a variety of approaches to manipulate genes in Hydra in an attempt to understand the molecular foundations of the remarkable biology of this seemingly simple animal. Hydra is a member of the animal phylum Cnidaria, which is the sister group to Bilateria, the animal group that includes humans; thus our studies with Hydra will inform us about human biology.
