Alligator expert Lou Guillette will give a public lecture, "Environmental Contaminants and Health: Lessons from Wildlife," at Wichita State.

Guillette is the distinguished professor of zoology at the University of Florida. His speech will be at 5:30 p.m. Wednesday, Feb. 6, in 209 Hubbard Hall.

That will be followed two days later by a technical lecture, "Contaminants and the Developing Reproductive System: From Populations to Genes," at 10:30 a.m. Friday, Feb. 8, in 231 Hubbard Hall.

Both events are free and open to the public.

At the University of Florida, Guillette studies the mechanisms by which environmental factors influence the evolution, development and functioning of the reproductive system in vertebrates.

The lectures are part of the Watkins Visiting Professorship, which was created in 1974 from the Watkins Foundation to provide WSU's biology, chemistry, geology and physics departments with one visiting professor each year.
