Tim Oakes: Forthcoming book culminates a four-year project on the technopolitics of nuclear power in Asia Gabriela Rocha Sales Mon, 12/08/2025 - 14:23

Between 2021 and 2024, working in collaboration with the Center for Asian Studies, Tim Oakes hosted a series of four workshops on nuclear power development and disaster in Asia. The workshops were funded by a generous grant from the Albert Smith Nuclear Age Fund. The first, held in commemoration of the 10year anniversary of the Fukushima nuclear meltdown in Japan, explored how people in Japan have lived with the aftermath of this disaster. The second focused on China’s efforts to expand its nuclear power industry and export its nuclear technology. The third examined the broader political and cultural configurations of the nuclear realm from an Asian perspective, while a fourth workshop brought together most of the participants of all three previous workshops for a final extended discussion on what we might learn from the different aspects of nuclear power development and disaster in Asia.

While the issues swirling around nuclear power are often portrayed in purely technical terms, the workshops sought to demonstrate that nothing is ever ‘just technical’. The project’s sociotechnical perspective sought to recognize that nuclear power enrolls people, as individuals and as groups, into a particular and peculiar set of relationships with technology. Those relationships blur the boundaries between science and society, and between technology and culture, in unique and compelling ways. How do people – in their everyday lives – understand and practice their relationship to radiation? How do they calculate different kinds of risk? How do they come to be involved in the measurement of radiation and the science of predicting its health-related effects? What have been the unexpected political outcomes of people’s encounters with nuclear technology? How do we define responsibility when considering the risks and benefits of nuclear energy? How have cultural practices been shaped by people’s relationship with the technologies and infrastructures of nuclear power, or with the technological interventions brought about by the disaster? These are just some of the questions workshop participants grappled with.

Along with CU ��ý�� Anthropologist Kate Goldfarb, Oakes is co-editing a collection of papers from the workshops in a volume to be published in 2026 by the University of Toronto Press. Living in Nuclear Asia: Sociotechnical perspectives on nuclear power development, risk, and vulnerability will, in the broadest sense, address what it means to survive in the nuclear age in Asia. Collectively, the chapters in the book ask: what do we learn by paying attention to Asian experiences of ‘nuclearity’? Nuclear power is typically written about from the policy perspectives of proliferation, containment, and security. This is especially the case regarding work on nuclear development in Asia. Living in Nuclear Asia marks a departure from this trend, emphasizing instead nuclear technologies themselves, including nuclear power infrastructures, and the socio-cultural, economic, and political relations that swirl around them.

Morteza Karimzadeh: New AI Methods Are Reshaping How Geographers Model Air Pollution and Wildfire Smoke

Morteza Karimzadeh: New AI Methods Are Reshaping How Geographers Model Air Pollution and Wildfire Smoke Gabriela Rocha Sales Mon, 12/08/2025 - 14:20

As wildfire seasons intensify and air pollution continues to threaten public health, geographers are turning to new generations of artificial intelligence models to understand how environmental hazards unfold across space. Geography Professor Morteza Karimzadeh, PhD student Zhongying Wang, and collaborator Dr. James Crooks of National Jewish Health are developing next-generation models that combine satellite data, atmospheric information, and AI-driven “place signatures” to better estimate air pollution across the United States.

Their latest publication accepted in GIScience and Remote Sensing focuses on PM₂.₅, a harmful form of air pollution linked to asthma, cardiovascular disease, and premature mortality. Traditional approaches rely on networks of ground-based monitors and satellite-derived aerosol data, but both leave important gaps. Many communities, especially in rural regions or areas affected by sudden wildfire smoke, lack reliable monitoring. Pollution also varies dramatically from one neighborhood to the next. This creates both scientific and equity challenges.

To address these gaps, the team built a deep learning model that synthesizes 21 days of satellite observations, meteorological variables, wildfire smoke information, and other environmental data to estimate daily PM₂.₅ at high spatial resolution. The model is designed to follow how pollution evolves over time, capturing the dynamics of major smoke events and seasonal changes. But their latest innovation adds something novel to the discipline: geospatial foundation models, including “location encoders” such as GeoCLIP, incorporated in a practical way for dynamic air pollution estimation. These models learn from millions of ground-level photographs—urban streetscapes, forests, industrial landscapes, suburban neighborhoods—to produce rich, 512-dimensional embeddings that describe the visual and contextual character of places. When incorporated into the air-quality system, these learned representations provide information about land use, vegetation, density, and built environments that traditional datasets often miss.

“Location encoders give our models a deeper understanding of what a place is like,” says Karimzadeh. “They capture signals that satellites alone can’t see—traffic corridors, industrial zones, tree cover—and that helps us estimate pollution more accurately, especially in places with few monitors.”

The impact is clear in case studies like the 2021 Dixie Fire, when thick smoke blanketed large portions of the western U.S. Models enhanced with location embeddings captured not only the concentration of PM₂.₅ but also the full spatial extent of the smoke plume with greater precision and coherence than satellite-only approaches.

For Wang, who leads much of the model development, has been pursuing this goal of building models that generalize well and provide reliable information even where monitoring is sparse.

In the future, the team aims to incorporate additional sensors and imagery into their models, and explore seasonal and long-term place representations. Their research reflects a broader paradigm in geography and environmental science: using AI not to replace traditional observation methods, but to complement and strengthen them.

Figure from the published paper: Estimated PM2.5 during the 2021 Dixie Fire (Northern California) produced by the baseline model (without geographic features) and the GeoCLIP-enhanced model. Each row corresponds to a different day during peak wildfire activity. Columns (a) and (b) show baseline results, while columns (c) and (d) present GeoCLIP-enhanced estimates at both CONUS and regional scales. The GeoCLIP model yields more intense and spatially coherent smoke plumes and additionally identifies elevated PM2.5 levels over northern Minnesota on July 21, reflecting long-range smoke transport from simultaneous western U.S. and Canadian wildfires.

ESIIL’s Third Annual Innovation Summit: Catalyzing Collaboration for Environmental Solutions Gabriela Rocha Sales Mon, 12/08/2025 - 14:04

Rachel Lieber , Community Engagement Specialist at ESIIL

The Environmental Data Science Innovation and Impact Lab (ESIIL), a next-generation NSF synthesis center directed by Geography Professor Jennifer Balch, hosted its third annual Innovation Summit this September, bringing together over 100 researchers, data analysts, environmental professionals, and thought leaders to tackle questions around environmental tipping points and transformations. The Summit featured ESIIL’s flexible and interactive “unconference” format, which encourages collaboration and innovation. Participants self-organized into groups around topics that sparked their interest, co-creating innovative approaches through spontaneous interaction and cross-disciplinary teamwork. Over two and a half days, this dynamic process resulted in the formation of twelve working groups.

In preparation for the event, participants joined a virtual “Science Jam” to brainstorm research questions, datasets, and potential products. The ESIIL team then crafted the in-person agenda around the most promising ideas that emerged. To ensure all attendees were ready to dive into data-driven exploration, ESIIL also offered two virtual technical training sessions on big data and cyberinfrastructure providing participants with access to cutting-edge analytical tools for exploring environmental tipping points.

Equipped with technical skills, inspiring ideas, and potential collaborations, attendees gathered at CU ��ý�� for two and a half days of intentional innovation. Summit goals included exploring big data to understand environmental tipping points, promoting ethical open-science practices, championing responsible AI use, and strengthening collaboration across disciplines and career stages.

The Summit opened with a blessing from Phil Two Eagle, long-time ESIIL collaborator and member of the Rosebud Sioux Tribe, who reminded participants of their interconnectedness with one another and the Earth. Jennifer Balch then delivered a call to action, emphasizing the importance of diverse perspectives in advancing solutions to complex environmental challenges, especially in times of uncertainty.

ESIIL’s facilitation team, Divergent Science (back for a second year with ESIIL), facilitated the group formation process, guiding participants through structured exercises that helped them refine ideas, connect around shared interests, and define their desired outcomes. Once teams formed, they received the tools they needed to get to work: a collaborative workspace, access to shared GitHub repositories, CyVerse resources, and on-call troubleshooting support from the ESIIL team.

Over the course of the Summit, teams evolved their projects from defining hypotheses on Day 1, to diving into data analysis using ESIIL’s OASIS data library on Day 2, to preparing final presentations on Day 3. Topics included:

How the order, duration, frequency, and intensity of disturbances influence forest regime shifts
Mapping thresholds that distinguish abrupt ecosystem changes from gradual transitions
Understanding how interacting stressors reshape aquatic food-webs and affect ecosystem stability
Identifying linked disturbances and effective management interventions
Improving data interoperability and harmonization across environmental datasets

All project materials and team repositories are available here: ESIIL Innovation Summit 2025 Group Repos.

The Summit concluded with group presentations and concrete commitments to ongoing collaboration. Many teams plan to submit manuscripts to ESIIL’s special issue in Environmental Data Science on “Solution-Based Data Science for Environmental Challenges,” while others will apply for ESIIL working group funding to continue their efforts over the next two years.

Each year, ESIIL’s Innovation Summit helps grow a global community of environmental data scientists equipped with the skills and tools to leverage big data for real-world environmental solutions. This cutting-edge work takes “all hands on deck” and collaborating across diverse perspectives, disciplines, and areas of expertise requires skills that must be taught, shared, and practiced. The ESIIL Innovation Summit strives to actively cultivate these skills and provide a space where intentional innovation can flourish.

Federico Andrade Rivas Joins the Geography Department as Assistant Professor Gabriela Rocha Sales Mon, 12/08/2025 - 13:54

My path to becoming an Assistant Professor at the Geography department started in Colombia, where I studied environmental engineering and anthropology. After working in a malaria surveillance and climate change adaptation project with nomadic Indigenous populations in the Amazon, I realized that my passion was to understand the complex determinants of human health disparities. Thus, I decided to pursue a Master of Public Health at the University of Cape Town, excited to learn from “South-South” collaborations on chemical contamination issues. The drive to understand human health as deeply intertwined with the natural environment led me to join emergent approaches to human health, such as planetary health, and to pursue a PhD at the University of British Columbia. In Canada, I had the privilege to collaborate in “North-South” partnerships on pollution and globalized food systems, as well as work in solidarity with First Nations and Inuit on the nutritional benefits and contamination issues of traditional food systems.

Currently, my scholarship sits at the intersection of human well-being and the integrity of ecosystems that support life on Earth. I focus on applying a creative combination of geospatial, quantitative, and qualitative research methods to assess contamination issues at global, national, and local scales. I do this while elucidating connections between pollution threats to other planetary health challenges and drivers of health disparities, such as environmental change. I strive to conduct relevant and meaningful research that is genuinely interdisciplinary, collaborative, and focused on solutions and communities’ aspirations beyond solely evaluating damage.

When I am not conducting research or teaching, you can find me rock climbing, brewing coffee, or sharing time with my family.

Keith Musselman: Warming Alaska Rivers Threaten Salmon and Indigenous Food Security, INSTAAR–Geography Team Finds

Keith Musselman: Warming Alaska Rivers Threaten Salmon and Indigenous Food Security, INSTAAR–Geography Team Finds Gabriela Rocha Sales Fri, 12/05/2025 - 11:42

A recent CU ��ý�� Today news article highlighted new research led by Peyton Thomas, a new Assistant Professor at the Institute of Arctic and Alpine Research (INSTAAR) and ENVS. Peyton was formally a postdoctoral researcher co-advised by Geography Assistant Professor Keith Musselman. The study, published in Scientific Reports, examines how rapid climate warming in Alaska is altering river conditions and threatening Chinook salmon populations that Indigenous communities have depended on for millennia.

For many Alaska Native and First Nations communities along the Yukon River, steep declines in Chinook salmon since the early 2000s have already caused major disruptions to food security, cultural practices, and travel across frozen rivers. The research team collaborated closely with tribal partners to understand ongoing changes and support community-led adaptation efforts.

Using a combination of climate simulations, hydrologic modeling, and fish growth models, the team assessed how future warming may affect two key subsistence species: Chinook salmon and Dolly Varden (a trout species). Their results suggest that by mid-century, summer river temperatures in parts of the region may regularly exceed the thermal tolerance of juvenile Chinook, further constraining populations. In contrast, Dolly Varden may benefit from slightly warmer water, offering a potential—though culturally complex—alternative for some communities.

Importantly, the team identified several river systems that are likely to remain suitable for Chinook habitat, highlighting priority areas for conservation and restoration.

This work reflects an ongoing collaborative effort between CU researchers and Indigenous communities across Alaska. Over the past two summers, Thomas, Musselman, and colleagues have visited numerous tribal communities to document environmental change, integrate local knowledge with modeling tools, and help identify strategies for navigating an uncertain future. The project also aligns with broader efforts to clarify how climate-driven shifts in hydrology are shaping ecosystems and livelihoods in Arctic and subarctic environments.

For those interested, the full University news feature provides deeper context on the study and its implications for future river management, salmon conservation, and community resilience.
