"Asteroids as Records of Solar System History"

Francesca DeMeo

February 25, 2016
DTM Weekly Seminar Series
Francesca DeMeo

Francesca DeMeo, a research scientist at the Massachusetts Institute of Technology, will give a talk titled, "Asteroids as Records of Solar System History" , at 11 a.m. on Thursday, 25 February 2016, in the Greenewalt Lecture Hall as part of DTM's Weekly Seminar Series.

DeMeo received her Ph.D. in astronomy and astrophysics from the Observatoire de Paris in 2010. Her field of expertise is understanding the surface compositions of asteroids and Kuiper Belt Objects through visible and near-infrared spectroscopic measurements. Because asteroids are the remnants of solar system formation and the leftover building blocks of the planets, studying their composition and distribution reveals the conditions of solar system formation and provides evidence of the dynamical evolution since formation.

Coffee, tea, and a continental breakfast will be served before the lecture at 10:30 a.m.

"Sulfur isotopic variability in meteoritic materials"

James Farquhar

DTM Weekly Seminar Series
James Farquhar

James Farquhar, a professor at the Earth Systems Science Interdisciplinary Center and Department of Geology at the University of Maryland, will give a talk titled, "Sulfur isotopic variability in meteoritic materials", at 11 a.m. on Thursday, 18 February 2016, in the Greenewalt Lecture Hall as part of DTM's Weekly Seminar Series.

Farquhar received his Ph.D. in Earth and atmospheric sciences from the University of Alberta in 1995. He is interested in table isotope geochemistry, including atmosphere-surface interactions, atmospheric evolution, sulfur and oxygen biogeochemistry, meteorite studies, isotopic exchange and thermometry.

Coffee, tea, and a continental breakfast will be served before the lecture at 10:30 a.m.

“Images and spectra of extrasolar planets”

Bruce Macintosh

Bruce Macintosh, a physics professor at Stanford University, will give a talk titled, “Images and spectra of extrasolar planets,” at 11 a.m. on Thursday, 11 February 2016, in the Greenewalt Lecture Hall as part of DTM's Weekly Seminar Series.

Macintosh received his Ph.D. in astronomy from the UCLA in 1994. His specialities include adaptive optics, high-contrast imaging, and direct detection of extrasolar planets.

Coffee, tea, and a continental breakfast will be served before the lecture at 10:30 a.m. 

"The First Billion Years on Mars: Insights from Crustal and Sedimentary Records"

Kevin Lewis

DTM Weekly Seminar Series
Kevin Lewis

Kevin Lewis, an assistant professor in the Department of Earth and Planetary Sciences at Johns Hopkins University, will give a talk titled, "The First Billion Years on Mars: Insights from Crustal and Sedimentary Records",  at 11 a.m. on Thursday, 4 Febraury 2016, in the Greenewalt Lecture Hall as part of DTM's Weekly Seminar Series.

Lewis received his Ph.D. in planetary science from Caltech in 2009. His research focuses on problems in planetary geophysics, from the scale of a grain of sand all the way up to the crust of a planet. He has worked in depth on the nature of sedimentary rocks of Mars, and what they might record about that planet's past climate and habitability. He is also interested in understanding the large-scale properties of planetary lithospheres using magnetic, gravity, and topography data sets.  

Coffee, tea, and a continental breakfast will be served before the lecture at 10:30 a.m.
