Patrick Larkin received his Ph.D. in the Department of Neuroscience at the University of Florida in 2000. During his tenure as a Post-doctoral Associate at the University of Florida he developed and validated gene chips (microarrays) in largemouth bass, sheepshead minnows, and blue crabs. He used these tools to examine how endogenous hormones and anthropogenic compounds influence reproductive and detoxification pathways in these species. From 2002-2006 he was head of the science operations for a biotechnology company that was developing genetic based assays for water testing. Since 2001, he has published, or has in press, twenty-one scientific articles, book reviews, and reports on the subjects of microarray technology, PCR, and other molecular based assays in regards to water testing. Dr. Larkin currently is an Independent Consultant in the EcoToxicology field and also teaches various biology classes part-time at Santa Fe Community College, which is located in Gainesville, Florida. He also currently sits on the Editorial Board for the Environmental Bioindicators journal.
