L’atterrissage du module de Rosetta sur la comète 67/P et ses rebondissements

Claudia Alexander has a Ph. D. from the University of Michigan in space plasma physics. She has a master’s degree from UCLA, and a bachelor’s degree from the University of California, Berkeley.

Alexander served on NASA’s historic Galileo mission to Jupiter, eventually becoming the Project Manager, where she had the pleasure of crashing the spacecraft into the planet (on purpose!). She served as Project Staff Scientist on the equally historic Cassini mission to Saturn; as the Principle Investigator of a future mission concept called ‘Gem;’ and currently serves as the U.S. Project Scientist on NASA’s contribution to the International Rosetta mission.

Alexander studies surface bound exospheres of frozen bodies such as Jupiter’s moon Ganymede, thermophysical properties of comets, and recently the properties of the collapse of the natal solar nebula. She is publishing her science-learning book series: Windows to Adventure, for middle-grade readers (4th-5th grades). The first book in the series, called Venus, the Morning Star, just won a Mom’s Choice Award. The next one, recently released, is titled Which of the Mountains is Greatest of All?

Alexander will deliver her lecture at 2:00 P.M. in English.

Michel Photo  - Public LectureIce Sheets Mass Loss and Sea Level Rise: Geological Archives, from Québec to Australia; Fonte des calottes glaciaires et relèvement du niveau de la mer: les archives géologiques, du Québec à l’Australie

Michel Lamothe completed his Ph.D. at Western Ontario on the glacial history of Southern Québec. With academic and applied experiences, including teaching in Western Africa and leading mineral tracing research at the Geological Survey of Canada, Lamothe has developed a unique expertise in luminescence dating of Quaternary sediments in geological and archaeological contexts.

He contends scientists should all be concerned about the current and predicted mass losses of the Greenland and Antarctic ice sheets and the fate of world sea level. Lamothe teaches advanced geomorphology and global changes at the Université du Québec à Montréal.

Note: Lamothe will deliver his lecture at 3:00 P.M. in French.
