    30 | The Future of the O'Neill Leadership Center with Karen Gahl-Mills and Matthew Baggetta

    In 2019, Paul O’Neill showed his dedication to Indiana University and the School of Public and Environmental Affairs by making a transformative $30 million gift, leading to the school being named in his honor. One of the motivating factors behind the gift was the establishment of the Paul H. O’Neill Center for Leadership in Public Service dedicated to strengthening society by cultivating the next generation of innovative and ethical leaders for positive impact. Building on the O’Neill School’s more than 50-year commitment to advancing the public good, the center enhances student leadership programs, expands executive education opportunities, and bridges research with real-world solutions. It also fosters new pathways for experiential learning, professional development, and community engagement. Earlier this week, the O’Neill Leadership Center announced new co-directors, Karen Gahl-Mills and Matthew Bagetta, who will lead the OLC as it expands student leadership programming and strengthens community-engaged scholarship. We’re thrilled to be joined today by Karen and Matt to talk about the future of this critical center. Karen Gahl-Mills is a professor of practice at the O’Neill School and serves as the O’Neill School’s director of Arts Administration Programs. She applies practical lessons learned during her distinguished career to her administrative work, and to teaching courses in nonprofit governance, leadership, strategy, fundraising, and public policy. Associate Professor Matthew Baggetta is an expert on civil society and volunteer associations. His research interests include civil society and civic engagement, membership-based organizations, and social movements. Baggetta’s work focuses on the impacts of volunteer associations on their members and the broader impacts of associations and movements on society.

    29 | The Human and Economic Toll of El Niño with Chris Callahan

    Every day the news is filled with stories on extreme weather, its impact on human lives, and the economic impact of disasters. In 2026, the state of Indiana has already set a record for the sheer number of tornados in a year according to the National Weather Service, and there were 58 confirmed tornados in June alone in the state. The number of tornados doesn’t show a picture of the larger climate situation, but they are a symptom, particularly when shown over time. Four of the top five years with the most tornados have happened in the past four years, and the extreme weather events continue to rack up massive dollars’ worth of damage. Flooding rains in Indiana have impacted multiple parts of the state, and weather-related disasters are seemingly always in the news. That’s just here in Indiana. The same story is repeated at locations around the world, but data surrounding the human and economic impact of these events, be it from extreme heat, cold, storms, or other weather events, can be maddeningly difficult to attain or is controversial. We’re joined today by Assistant Professor Christopher Callahan from the O’Neill School. Chris is a climate scientist whose work focuses on the economic and social impacts of climate change. He uses tools from both physical climate science and quantitative social science to assess how to extreme climate events such as heat waves and El Niño events affect human health and economic growth around the world. He has also worked to develop quantitative frameworks for climate accountability, showing how major countries and fossil fuel firms have altered local climate and amplified the resulting social impacts across the globe.

    28 | Looking back on the Siân Mooney Era at O'Neill

    For the past seven years, Siân Mooney has served as the dean of the O’Neill School, leading the school through its most prestigious era in its half-century of history. First and foremost, there is the recognition from U.S. News and World Report, which ranks the O’Neill School’s Master of Public Affairs program as the top graduate program of its kind in the nation. Along with the top-ranked MPA, four concentrations at the O’Neill School, including environmental management and policy, health policy and management, nonprofit management, and public finance and budgeting also are ranked No. 1. Additionally, multiple other concentrations rank in the top 10 in the country, including the nonprofit management programs at O’Neill’s Bloomington and Indianapolis campuses holding the top two rankings in the country. Beyond the rankings, Dean Mooney has guided the school through record enrollment, the establishment of the Environment, Society, and Sustainability Institute, eight new degrees and certificates across IU Bloomington and IUI, more than $60 million in awards since 2019, more than $24 million in raised gifts, a growing portfolio of international partnerships, the hiring of 53 faculty members, including 37 tenure-track faculty members… the list goes on and on. But all great times must come to a close, and this spring, Dean Mooney announced she would be pursuing her next chapter and stepping down as dean effective June 30. We’re thrilled to have Dean Mooney—who was the first-ever guest of O’Neill Speaks—join us to talk about her time at O’Neill, what her experience was like, and what’s next.

    27 | The O'Neill Sustainability Internship w/McKenzie Jones, Mae Allen, and Jessica Davis

    Sustainability has long stopped being just a corporate buzzword or nice elective. It’s a critical part of planning in just about every aspect of our lives, the fundamental operating system for a world facing rapid climate shifts and resource scarcity. It’s about building systems that are regenerative rather than just extractive, ensuring that our progress today doesn’t become a debt for the generation of tomorrow. And the generation of tomorrow is already playing their part. At the O’Neill School on both our Bloomington and Indianapolis campuses, sustainability interns conduct holistic assessments of the O’Neill School and its operations to identify areas where improvement is needed. Studying things isn’t enough. Awareness is critical, as well, and the group has built a website to allow stakeholders to understand where and how improvements can make a difference. O’Neill Speaks is joined today by McKenzie Jones, Mae Allen, and Jessica Davis. McKenzie is the Bloomington Sustainability Intern at O’Neill is a second-year graduate student working toward a Master of Public Administration as well as a Master of Environmental Science with a concentration in Energy and Climate Change Solutions. Mae is the O’Neill sustainability intern on the IU Indianapolis campus pursuing a degree in sustainable practices and policy. Jessica is IU’s Associate Vice President and Chief Sustainability Officer and is an associate faculty member at the O’Neill School.
