JGJudi Greenwald ’82
Executive Director of the Nuclear Innovation Alliance.

Judi Greenwald is a fellow at Princeton University’s Andlinger Center for Energy and the Environment and is the principal of Greenwald Consulting. She has over 35 years of energy and environmental policy leadership experience in the public and nonprofit sectors, including the U.S. Congress, the White House, the Environmental Protection Agency, the Department of Energy, the Nuclear Regulatory Commission and the Center for Climate and Energy Solutions (C2ES, formerly the Pew Center on Global Climate Change). Greenwald has focused extensively on deep decarbonization through the interplay of public policy, technology innovation, human behavior and markets. Highlights of her distinguished career include working on the 1990 Clean Air Act Amendments as congressional committee staff; overseeing energy and environmental programs at C2ES and the Department of Energy; co-founding the Carbon Capture Coalition; advising U.S. state and regional greenhouse gas initiatives; and collaborating with stakeholders to advance both economic and environmental goals. Greenwald received an M.A. in Science, Technology and Public Policy from George Washington University.


DKDouglas Kelbaugh ’67 *72
Architect; Professor Emeritus of Architecture and Urban and Regional Planning; and Former Dean at the University of Michigan’s Taubman College of Architecture and Urban Planning

After receiving a master’s degree in architecture from Princeton University, Douglas Kelbaugh headed Kelbaugh + Lee, an architecture firm that won 15 design awards and competitions and pioneered the design of passive solar buildings. While architecture chair at the University of Washington, he was also principal in Kelbaugh, Calthorpe and Associates. At the University of Michigan, Kelbaugh served as dean of Taubman College between 1998-2008, starting the Urban Design program and hiring 40 tenured and tenure-track faculty. After stepping down as dean, he was vice president of design and planning for a large development company in Dubai, working on major projects in the Middle East, Southeast Asia, Europe and Africa. Returning to full-time teaching in 2010, Kelbaugh was awarded the 2016 Topaz Medallion for Excellence in Architectural Education, the highest award in the field. He has authored and edited numerous books, including: “The Pedestrian Pocket Book,” a 1989 national bestseller that helped jumpstart New Urbanism and Transit-Oriented-Development. His most recent book, “The Urban Fix: Resilient Cities in the War against Climate Change, Heat Islands and Overpopulation,” makes the case that cities are our last best hope for the future of our species and its civilization.

TLTom Leyden ’77
Vice President of Solar Landscape

A pioneer of the solar industry, Tom Leyden started his own company back when the focus was on thermal solar used for residential and commercial rooftops. Once photovoltaics came of age, his experience broadened to encompass a variety of solar applications across the globe. As vice president of sales and marketing at EPV, a thin-film photovoltaic manufacturer, and at WorldWater, a remote-power and water-pumping company, he oversaw the installation of community projects in Africa and Asia. In 2012 he became CEO of the start-up Solar Grid Storage, later acquired by Sunedison. Today, Leyden is vice president at Solar Landscape, a New Jersey-based company developing cutting-edge projects in community solar. Solar Landcape’s customers include Johnson & Johnson, Bloomberg, Tiffany’s and Monmouth University, but Leyden is proudest of his work with Princeton University. He has developed over 20 megawatts of solar at nine sites across campus, helping Princeton toward its goal of achieving carbon neutrality by 2046. Leyden has served the solar industry in other roles, including as president of the N.J. Solar Industry Association and board member of the national Solar Industry Association. Leyden is part of a proud Tiger family that includes his wife, Connie ’78, and daughter Taylor ’12.

BABevin Ashenmiller ’92
Professor of Economics, Occidental College

A Slavic languages and literature major at Princeton, Bevin Ashenmiller pivoted towards economics after graduation, wanting to use economic tools to solve environmental problems. Her early work focused on individual and household recycling behavior, and she joined the faculty at Occidental College in 2005. After spending the 2012-2013 academic year working as the senior economist for energy and the environment at the White House Council of Economic Advisers in Washington, D.C., she refocused her research on climate adaptation policy with a focus on stormwater. Currently, Ashenmiller is working on research to quantify the value of the non-market benefits of nature-based interventions. Her particular focus is on how well-designed green infrastructure projects built on urban public-school campuses can support climate adaptation policy by managing stormwater and providing ecosystem services while simultaneously improving the academic, behavioral and health outcomes of children.

SOShannon Osaka ’17
Reporter, Grist

A climate reporter at the online environmental magazine Grist, Shannon Osaka has also written for Rolling Stone, Wired and other outlets. Her work focuses on U.S. and international climate policy, electric vehicles and the energy transition. She has written feature stories on novel democratic experiments in climate policy, the political challenges of a carbon tax, and the spillover of infectious diseases. In 2021, she received the SEAL Award for Environmental Journalism and an Online Journalism Award for topical reporting on climate change. At Princeton, Osaka completed an independent major in environmental science and environmental studies, and then spent two years as a Sachs Scholar at the University of Oxford, where she received a master’s degree in geography. While at Oxford, she founded an international student climate magazine and published several academic papers on perception of climate change and extreme weather. She and a colleague are currently working on a book about conceptions of nature under anthropogenic climate change.
