In this episode of Talking Environment, host Gevorg Ghazaryan speaks with Dr. Maryia Bakhtsiyarava from Drexel University about how climate change, urban inequality, and health outcomes are deeply connected, and how data can help us respond more justly.

Dr. Bakhtsiyarava explains how environmental exposures like heat and air pollution disproportionately affect vulnerable communities, and how spatial data science and GIS can illuminate patterns of environmental injustice. The episode highlights the role of research institutions in advancing climate equity and what cities can do to protect public health in a warming world.

Tune in to learn how combining science, compassion, and data can create more resilient and equitable communities.

In this episode of Talking Environment, host Gevorg Ghazaryan speaks with Dr. Neeti Bathala—Fulbright Specialist, Smithsonian Journeys Expert, and Drexel University professor—about her work in tropical conservation and environmental education.

The conversation highlights Dr. Bathala’s community-based conservation efforts in Belize and Costa Rica, including lionfish population control and partnerships with sea turtle protectors. She also discusses how education can bridge the gap between global environmental science and local realities, and why hope, culture, and collaboration are key to protecting fragile ecosystems.

Tune in to discover how science, students, and communities are coming together to lead sustainability efforts in some of the most vulnerable corners of our planet.

In this episode of Talking Environment, host Gevorg Ghazaryan talks with Dr. Jane Dmochowski of the University of Pennsylvania about how we teach, translate, and communicate environmental science in a rapidly changing world.

Dr. Dmochowski discusses the challenges of making climate change understandable to the public, the evolving role of universities in climate communication, and how satellite remote sensing can reveal the hidden stories of environmental change. She also reflects on the value of storytelling in sparking action and how today’s students are redefining climate leadership. Tune in to explore the future of environmental education and how knowledge becomes a tool for change.

In this episode of Talking Environment, host Gevorg Ghazaryan is joined by Dr. Jane Clougherty, Professor of Environmental and Occupational Health at Drexel University’s Dornsife School of Public Health, for a deep and timely conversation on the intersection of air quality, social stress, and public health.

Dr. Clougherty shares her research on how environmental exposures, especially air pollution, combine with chronic stressors to create unequal health outcomes, particularly in urban communities. The conversation explores what cities can do to respond to these complex challenges and how climate change is further complicating air quality and health equity.

You’ll also hear about innovations in exposure tracking, the role of community data, and what it takes to center justice in environmental health planning.

In this episode of Talking Environment, Gevorg Ghazaryan speaks with Dr. Frederick Steiner, Dean of the Weitzman School of Design at the University of Pennsylvania, about the urgent role of ecological planning in shaping cities of the future.

Dr. Steiner unpacks the core principles of ecological design, explains why cities are critical to climate adaptation, and highlights the importance of integrating equity into urban planning. The episode touches on current planning mistakes, emerging models of resilient design, and how educators and institutions can prepare the next generation of environmental designers.

Tune in to hear how systems thinking, collaboration, and visionary planning can transform the built environment for people and the planet.

In this episode of Talking Environment, host Gevorg Ghazaryan is joined by Dr. Laura Toran, Professor of Earth and Environmental Science at Temple University, for a deep dive into one of the most essential but often overlooked topics in environmental science - urban water systems.

From stormwater to sinkholes, Dr. Toran explains how water moves through cities, why flooding is getting worse, and what urban planners and everyday citizens can do to manage water more sustainably. The conversation also explores karst hydrology, pollution pathways, groundwater risks, and how science and technology are helping us better understand what happens beneath our feet.

Whether you’re interested in climate resilience, infrastructure, or just curious about where rainwater really goes - this episode will change how you think about water in cities.

In this episode of Talking Environment, host Gevorg Ghazaryan sits down with Dr. Sean O'Donnell, Professor of Biodiversity, Earth & Environmental Science at Drexel University, to delve into the fascinating world of social insects and their responses to environmental stressors.

Dr. O'Donnell shares insights from his research on insect behavior and neuroecology, focusing on how species like ants, bees, wasps, and termites exhibit complex social structures that enable them to adapt to challenges such as climate change and habitat loss.

The conversation explores the concept of "thermal sociobiology," examining how rising temperatures impact insect colonies and what these changes mean for broader ecosystems.

Dr. O'Donnell discusses the resilience of social insects, their role in maintaining ecological balance, and the lessons humans can learn from their adaptive strategies.
