Sigma Xi Distinguished Lecturers, 2011-2012


Potential hosts should contact lecturers directly to book events. In making arrangements, hosts should be specific about dates, lecture topic, scope of the lecturer's visit and any special accommodations that may be called for.

Each lecturer has designated his or her topic(s) for three different types of audiences. Where more than one level is shown, the lecture can be adjusted to the needs of the audience:

  • P (Public)
    Aimed at presenting scientific issues of general concern to a public audience.


  • G (General)
    Intended for a normal Sigma Xi audience of both scientists and other scholars representing a broad range of disciplines.


  • S (Specialized)
    Aimed at scientists and students in fields that are closely related to that of the lecturer.

  1. How the brain loses its balance in autism and other disorders (P)
  2. Balancing excitation and inhibition in the nervous system: Building a brain that works and a heart that doesn't work too hard (G)
  3. Developmental regulation of excitation and inhibition in the mammalian nervous system (S)

Professor in the Department of Biology, Neuroscience Program Volen Center for Complex Systems National Center for Behavioral Genomics Brandeis University Susan Birren is a professor of Biology and Neuroscience and a member of the Volen Center for Complex Systems at Brandeis University. She received her Ph.D. in Biological Chemistry from UCLA and carried out postdoctoral work in Neuroscience at the California Institute of Technology where she became interested in the development of the mammalian nervous system. Her current research addresses how the nervous system establishes and maintains activity patterns at levels that allow normal function. This work focuses on two critical physiological systems- the brain and the heart. Disruptions in the balance of excitatory and inhibitory neural activity have dire consequences in each of these systems. In the brain the loss of such homeostasis can lead to epilepsy or to developmental disorders such as autism. In the cardiac system, imbalances in excitation and inhibition underlie a range of cardiovascular disorders including hypertension and heart failure.

  1. The Ice-Age Dispersal of Humans to the Americas: Do Stones, Bones, and Genes Tell the Same Story? (P.G)
  2. The Search for the Origins of the First Americans: A New Prehistory of the Bering Land Bridge (P,G)
  3. Humans at the End of the Ice Age: Coping with Climate Change, Circa 10,000 BC (P,G)

Ted Goebel is an archaeologist who studies the Ice Age dispersal of modern humans to the Americas. His field work has been primarily in Siberia, Alaska, and the intermountain west of the United States, and he has investigated archaeological sites spanning from more than 50,000 years ago to 10,000 years ago. He earned his B.A. degree from Washington and Lee University in 1986, and his Ph.D. degree from the University of Alaska, Fairbanks in 1993. Goebel's dissertation focused on the emergence of modern humans and the Middle-to-Upper-Paleolithic transition in Siberia. Since then, his research has investigated the peopling of Beringia. He has excavated important archaeological sites containing some of the earliest evidence of humans in Beringia, and most recently directed field research at Serpentine Hot Springs, the Ice Age archaeological site yet found on the Bering Land Bridge itself. This site is significant in that it contains the first dated fluted spearpoints in Alaska, a hallmark of Clovis and other Paleoindian cultures in temperate North America. In the Great Basin of the western U.S., Goebel's research has focused on the transition from the Pleistocene to the Holocene, a period of significant climate change and human adaptation. Since 2000, he has directed excavations at the multi-layered Bonneville Estates Rockshelter (a dry cave in eastern Nevada), which contains a series of well-preserved cultural layers spanning from about 13,000 years ago to historic times. Goebel's research has been reported in a series of journal articles in Science, Current Anthropology, and Journal of Archaeological Science. Currently Goebel is Professor of Anthropology and Texas A&M University. He holds the Endowed Professorship in First Americans Studies and is Associate Director of the Center for the Study of the First Americans.
