Kostadin Kushlev, Dean’s Excellence in Teaching Award

Kushlev, an associate professor in the Department of Psychology and director of the Happy Tech Lab, received the Dean’s Excellence in Teaching Award.
His research examines how digital technologies — especially smartphones and social media — impact well-being, fragment attention and promote or undermine social connection. His work aims to identify ways technology can be designed to support happier and healthier lives.
Arik Levinson, Dean’s Excellence in Teaching Award
Levinson, a professor of economics at Georgetown University and a research associate at the National Bureau of Economic Research, received the Dean’s Excellence in Teaching Award.

He is currently one of the editors of the Journal of the Association of Environmental and Resource Economists. He previously served as Deputy Assistant Secretary for Climate and Energy Economics at the U.S. Department of the Treasury and as a senior economist at the White House Council of Economic Advisers.
Levinson’s recent projects calculate the degree to which industrialized countries have been offshoring their most polluting economic activities, and evaluate the way some industries and the U.S. government have proposed to calculate carbon emissions caused by grid-connected electricity use.
Josiah Osgood, Dean’s Excellence in Teaching Award
Osgood, a professor in the Department of Classics, received the Dean’s Excellence in Teaching Award.

Osgood has taught at Georgetown since 2002 and served as chair of the Classics department from 2016 to 2022. He regularly offers classes in Roman history and in Latin language and literature. For many years, he co-directed study abroad programs in which students visited archaeological sites in Greece, Turkey and Italy.
Osgood’s research focuses on politics in ancient Rome and he has written about civil war, Roman women and Roman historical writing, among other topics. He is currently working on research about senators and their families in imperial Rome.
Colva Weissenstein (G’11), Distinguished Staff Award
Weissenstein, the program manager for the American Studies Program, received the Distinguished Staff Award.

This award is given to staff who have a record of extraordinary service within a department or program, and who have demonstrated selflessness as people for others, cura personalis, commitment to community in diversity and creative leadership and service in support of academic excellence.

With expertise in film and media studies — particularly horror cinema and advertising — as well as university administration, Weissenstein brings both intellectual curiosity and organizational care to her work.
Weissenstein is especially proud of cultivating a vibrant, supportive community among American Studies students and faculty, where collaboration and connection are central. Through sustaining beloved program traditions, including pedagogical field trips, she has helped foster a culture defined by curiosity, creativity and playfulness. Committed to joy as a meaningful part of academic life, she works to ensure that the program remains not only rigorous, but also welcoming, dynamic and deeply human.

His new book, Ripples on the Cosmic Ocean: An Environmental History of Our Place in the Solar System, was published by Harvard University Press and Penguin, and is a Scientific American, New Scientist and Nautilus book of the year. He is currently editing several books on past climate change, including the forthcoming Oxford Handbook of Resilience in Climate History.
He also writes, narrates and produces The Climate Chronicles, an award-winning podcast, video series and website on the history of climate change.
