Sigma Xi's distinguished lecture series focuses on climate change

WEST LAFAYETTE, Ind. - Peter Raven, director of Missouri Botanical Garden and the George Englemann Professor of Botany at Washington University in St. Louis, will be the first speaker in the Purdue chapter of Sigma Xi's series of distinguished lectures on climate change and global sustainability.

The lecture, which is free and open to the public, is at 7:30 p.m. Sept. 2 in Loeb Playhouse in Stewart Center.

The Purdue chapter of Sigma Xi, a national research society, is celebrating its 100th anniversary this year with the lecture series.

The society attempts to foster research, cooperation and collegiality between groups on campus that don't normally see each other, said Elsa M. Janle, associate research professor and co-director of In Vivo Core for Botanical Center for Age Related Diseases at Purdue. She also is president of the Purdue chapter of Sigma Xi.

Raven has been a member of the National Academy of Sciences since 1977 and is a trustee of the National Geographic Society and chairman of the society's committee for research and exploration. He has received several prizes and awards for his work, including the National Medal of Science, the highest award for scientific accomplishment in the United States, in 2001.

He will speak on the topic "Attaining global sustainability: What should we do?"

Other Sigma Xi distinguished lecturers on climate change and global sustainability include:

* Daniel Pauly, professor and director of the Fisheries Centre at the University of British Columbia. He will speak at 7:30 p.m. Nov. 24 in the Dean’s Auditorium of Pfendler Hall on "Impacts of fisheries and global warming on marine ecosystems and food security."
