Dr. Sandra Alday is joined by Manomita Das of the Joint Centre for Disaster Research at Massey University. Together, they discuss what motivates people's behaviors before and after a disaster strikes. How do small acts of kindness impact the disaster landscape? Who is responsible for taking care of risks? And are we better off taking action as individuals or as communities? Learn more in this latest episode.

Dr. Sandra Alday is joined by professor of risk analysis and decision science, Robyn Wilson, to discuss how we perceive risks and make decisions.

In the early hours of July 4, 2025, a torrent of 100 billion gallons of rain fell on Kerr County, Texas causing the Guadalupe River to rise meters in minutes. This tragedy was followed by intense flooding throughout the Midwest and northeast. In this episode, host of Let's Talk Risk, Dr. Sandra Alday, is joined by Dr. David Johnson of Purdue University to talk risk and rainfall as they try to understand recent flooding that has devasted parts of the country.

On this episode of Let's Talk Risk, Robyn Wilson, Professor of Risk Analysis and Decision Science and Acting Associate Director of Research and Graduate Education, joins us to talk about the risks of developing a flexible and sensitive measure of risk perception.

On this episode of Let's Talk Risk, Cameron MacKenzie, Associate Professor at the IMSE Department at Iowa State University, joins us to talk about the risks of mass shootings in schools, malls, churches, and other public venues. 

On this episode of Let’s Talk Risk, Professor Jun Zhuang, the Morton C. Frank Professor of Industrial and Systems Engineering at the University of Buffalo, joins to talk misinformation on social media. Zhuang breaks down what misinformation on social media is and why it’s important for us to think about.

Benjamin K. Sovacool, professor at Boston University, University of Sussex, and Aarhus University, joins the podcast to discuss his new research on climate geoengineering. Sovacool dives into the risk tradeoffs of carbon removal and solar radiation management. His research highlights different risks in the climate system, and the institutional, political, behavioral, social and cultural risks that accompany deployment of new technology. To close out the podcast, Sovacool shares the three policy implications from the study. 

Dr. David Johnson, professor of industrial engineering with a joint appointment of political science at Purdue University, joins Let’s Talk Risk to discuss his most recent work on the inequities and health impacts of flooding. States and communities struggle when thinking about how to better incorporate equity consideration into their planning process. To combat this, Johnson explains a new metric to evaluate projects that normalize the value of homes: treating all households the same. Instead of trying to prioritize projects based on protecting value, Johnson and his fellow researchers created an alternative metric that thinks about protecting households, irrespective of their value.
