MIT OpenCourseWare has been one of the pioneers of open education, leading the way by offering free materials from MIT courses as early as 2001, when no other institutions were pursuing comparably ambitious initiatives. But in subsequent years, there’s been an explosion of activity in open education, led by faculty members, instructional designers, and librarians at institutions throughout the United States and worldwide. In this episode, we hear from senior manager of MIT Open Education collaborations, Dr. Shira Segal, who talks about MIT’s efforts to team up with and learn from open education practitioners at the Maricopa County Community College District in Arizona, whose energetic promotion of open educational resources has saved students over $270 million in textbook costs, and College of the Canyons in California, a leader in the Zero Textbook Cost movement. We also hear excerpts from interviews with four instructors from those colleges, who talk about the potential benefits and unexpected challenges of using open educational resources in general, and about what they learned from their experiences in adapting OCW materials for use in their own classes.

Sebastian Lourido is an associate professor of biology and a member of the Whitehead Institute. Sebastian studies human pathogens and seeks to unravel the genetic pathways that help parasites like Toxoplasma gondii exist in human cells. He hopes that his work will lead to new treatments for toxoplasmosis as well as drugs that could treat diseases caused by similar parasites.

Global food systems produce more than enough to feed the world—yet nearly one-third of all food is lost or wasted. Much of that loss happens far upstream, driven by perishability, cold chain failures, infrastructure gaps, climate pressures, and supply chain inefficiencies that span continents.
In this episode, we’re joined by Dr. Chris Mejía, founder and director of the MIT Emerging Market Economies Logistics Lab, along with Drs. David Hidalgo and Mauricio Gámez, researchers who model solutions for supply chain issues. They unpack why food supply chains are uniquely vulnerable to disruption, especially in emerging markets, and where the biggest opportunities exist to reduce loss. From circular economy models and food recovery strategies to AI-driven forecasting, optimization, and community-based distribution networks, the conversation explores how better logistics, smarter data, and cross-sector collaboration can help redesign food supply chains that are more resilient, sustainable, and equitable.
