Dr. Pigliucci is Chair of the Philosophy Department at CUNY’s Lehman College and has, not 1, not 2, but 3 PhDs (just to make the rest of us feel like lazy slackers). He has a PhD in Genetics from the University of Ferrara, Italy (1989), a PhD in Botany from the University of Connecticut (1994), and a PhD in the Philosophy of Science from the University of Kentucky (2003).
Dr. Pigliucci has published over a hundred technical papers and several books. His most recent technical book is Making Sense of Evolution: Toward a Coherent Picture of Evolutionary Theory (co-authored by Jonathan Kaplan; University of Chicago Press). He has a forthcoming book titled Evolution: The Extended Synthesis (co-edited with Gerd Muller, M.I.T. Press).
Professor Pigliucci has been awarded the Dobzhansky Prize from the Society for the Study of Evolution and has been elected fellow of the American Association for the Advancement of Science "for fundamental studies of genotype by environmental interactions and for public defense of evolutionary biology from pseudoscientific attack." He maintains a blog at http://rationallyspeaking.blogspot.com/
The talk is aimed to general audiences and completely free. It will be great. Here's the link to a promotional poster (PDF). Feel free to post it!
