Kerry Ressler - "Fear and its Inhibition: From Mice to Men"

Kerry Ressler, M.D., Ph.D., assistant professor of psychiatry and behavioral sciences at Emory University School of Medicine and Yerkes National Primate Center in Atlanta and an investigator at the Howard Hughes Medical Institute in Maryland, spoke about the basic neural circuitry of fear and fear extinction. Ressler received his Bachelor of Science in molecular biology from Massachusetts Institute of Technology, his Ph.D. in neurobiology from Harvard University and his M.D. from Harvard University School of Medicine.

His research examines neural plasticity modulators that regulate fear learning in amygdale, hippocampus and prefrontal cortex areas of the brain. In addition to considering convergent genetic approaches to understanding fear-related disorders, his talk also included information on how findings have been translated into new treatments for human fear-related disorders, including phobias, panic disorders and post-traumatic stress disorder (PTSD).

2010-11

Edward O. Wilson - "The Creation: An Appeal to Save Life on Earth"

Edward O. Wilson, Pulitzer Prize–winning author and Harvard biologist presented a lecture titled “The Creation: An Appeal to Save Life on Earth”. Wilson discussed the future of the planet, suggesting that those of faith and science alike should be concerned about Earth’s welfare. He presented a way of thinking that incorporated both science and religion as part of the basis for human existence, and advocated both as integral schools of thought in preserving the planet. 

The celebrated professor of biology at Harvard University is one of the most highly respected scientists in the world today. Hailed as one of America's 25 Most Influential People by Time magazine, he has twice received the Pulitzer Prize, for his books “Ants” and “On Human Nature.” He also edited the volume “Biodiversity,” which in 1988 introduced the term and launched worldwide attention to the subject. In 1984, with “Biophilia,” he introduced the concept of a genetically based tendency to affiliate and bond with parts of the natural world. His “The Diversity of Life” (1992), which brought together knowledge of the magnitude of biodiversity and the threats to it, had a major public impact. His most recent book, “The Creation: An Appeal to Save Life on Earth” (2006), concerns the survival of our planet, written in the form of an impassioned letter.

In addition to more than 20 books, Wilson has written more than 400 articles and received some 75 awards in international recognition for his contributions to science and humanity. For his conservation work, he has received the Audubon Medal of the National Audubon Society and the Gold Medal of the World Wide Fund for Nature.
