Suzanne O’Connell, professor of earth and environmental sciences, is the co-editor and co-author of the book, Women in the Geosciences: Practical, Positive Practices Toward Parity, published in May 2015 by Wiley and the American Geophysical Union.
The geoscience workforce has a lower proportion of women compared to the general population of the United States and compared to many other STEM fields. This volume explores issues pertaining to gender parity in the geosciences, and sheds light on some of the best practices that increase participation by women and promote parity.
Highlights include lessons from the National Science Foundation-ADVANCE; data on gender composition of faculty at top earth science institutions in the U.S.; implicit bias and gender as a social structure; strategies for institutional change; dual career couples; family friendly policies; the role of mentoring in career advancement for women; recruiting diverse faculty and models of institutional transformation.
O’Connell’s chapters are titled “Multiple and Sequential Mentoring: Building Your Nest”; “Learning to Develop a Writing Practice“; “Hiring a Diverse Faculty”; and “Lactation in the Academy: Accommodating Breastfeeding Scientists.”
O’Connell also is the faculty director of the McNair Program.

His recent work on the relationship between atmospheric carbon dioxide levels and climate over geologic time has had significant impact on the field of paleoclimatology.
Professor Rubenstein teaches courses in philosophy of religion; pre- and postmodern theologies; and the intersections of religion, sex, gender, and science. Her research interests include continental philosophy, theology, gender and sexuality studies, and the history and philosophy of cosmology. She is the author of Strange Wonder: The Closure of Metaphysics and the Opening of Awe, and Worlds without End: The Many Lives of the Multiverse.
Professor Ulysse offers courses on Crafting Ethnography; Haiti: Between Anthropology and Journalism; Key Issues in Black Feminism; and Theory 2: Beyond Me, Me, Me: Reflexive Anthropology. Her research examines black diasporic conditions. Her recent work combines scholarship, performance, and exposition to ponder the fate of Haiti in the modern world and how it is narrated in different outlets and genres. She is the author of Downtown Ladies: Informal Commercial Importers, A Haitian Anthropologist and Self-Making in Jamaica, and Why Haiti Needs New Narratives.

This semester, 21 senior earth and environmental science majors in the Senior Field Research Project (EES 398) course traveled to Puerto Rico to develop their research, data collection, analytical and presentation skills.
As part of the EES Department’s capstone course sequence, students are required to participate in a series of student-designed research projects. From Jan. 12-19, students performed independent research in the field.
“The overarching spirit is to have students participate in the full arc of a research project: from the design all the way to the presentation of the results,” said Dana Royer, associate professor of earth and environmental sciences, associate professor of environmental studies. Royer has co-taught the class three times, this year with Suzanne O’Connell, professor of earth and environmental sciences, faculty director of the Ronald E. McNair Post Baccalaureate Achievement Program.

Phillip Resor, associate professor of earth and environmental sciences, was recently interviewed on WNPR about an amazing part of Connecticut’s geological history. According to the story, several hundred million years ago, Connecticut was in the middle of a massive continental collision, which formed the super continent Pangea and pushed up huge mountains. Deep beneath the earth, a borderland beneath the two continents formed. Today, geologists call it the Lake Char fault system; it runs along the I-395 corridor in southeastern Connecticut.
Resor took WNPR reporter Patrick Skahill to East Haddam by Gillette Castle to walk along the banks of the Connecticut River, and showed him fine black patterns flowing through the hardened cliff which showed evidence of ancient earthquakes.
“That super-fine grain material actually is what we call ‘pseudotachylite.’ It was a melt — a frictional melt in the fault,” Resor said. “If you think about rubbing your hands together, you’ll get heat, right? So if you rub fast enough, you’ll raise the temperature to the point where you can actually melt the rock.”
Resor explained that as Pangea broke apart about 200 million years ago, the Atlantic Ocean began to open up. A little piece of that ancient continent called “Gondwana” had broken off and was left behind, stuck to Connecticut. Geologists call this zone “Avalonia.”

Research Professor Ellen Thomas grasps a glass-enclosed sample of hundreds of microfossils, each a white fleck of limestone barely visible to the human eye.
“The first time students look at these they say, ‘they all look the same to me,’ but in reality, they are all have very different shapes,” Thomas says. “Even under a microscope, it can be difficult for a new eye to see the differences, but each species has its own shape; some have a much more open, light structure because they lived floating in the oceans close to the surface. Others have denser shells and lived on the bottom of the ocean, or within the mud. And each one can tell us, in its chemical make up, what the environmental conditions were like at the time that they lived and built their shells.”
By studying and analyzing microfossils, Thomas and fellow scientists are able to explore aspects of climate change on a variety of timescales,
