Chain Reaction by ACS

This episode explores inclusion and belonging through conversations with leaders from three scientific societies: NOBCChE, AISES, and SACNAS. Bridgette Shannon reflects on becoming the first Black woman to earn a chemistry Ph.D. at the University of Arkansas and the importance of being authentically yourself while creating space for quieter voices. Mary Jo Ondrechen discusses how community and cultural identity can help scientists overcome feelings of isolation and imposter syndrome. Ingrid Montes shares her experiences navigating gender and language barriers and argues that diverse perspectives strengthen science. Together, their stories show that scientific excellence depends on ensuring everyone feels they belong.

“Sustainability” has become quite the buzzword, but what does it mean in the world of chemistry? In this episode of Chain Reaction, we explore ACS’ core value of sustainability through two conversations that reveal how chemistry can help solve some of society’s biggest challenges while keeping people and the planet safe.
First, we hear from Amy Cannon, co-founder and executive director of Beyond Benign and the recipient of the first degree in green chemistry. Amy shares her unexpected path into the field, how she helped launch one of the world’s first green chemistry educational programs, and why educating future scientists is essential for building a more sustainable world.
Next, we talk with Mary Beth Mulcahy, scientist at Sandia National Laboratories and editor-in-chief of ACS Chemical Health & Safety. Drawing from her own experience surviving a serious laboratory accident, Mary Beth explains why safety is a critical component of sustainability. From managing risk to designing systems that account for error, she highlights the often-overlooked human side of scientific work.

This episode explores lifelong learning, one of ACS’s core values, through conversations with two educators whose careers have been shaped by curiosity and growth. High school chemistry teacher Amiee Modic reflects on 40-plus years in the classroom, sharing how hobbies like baking, sailboat racing, and reading continue to teach her new skills and inform her teaching. ACS education professional Karen Trimmer then discusses returning to school mid-career, finding purpose in mission-driven work, and embracing learning beyond traditional classrooms. Together, they show that lifelong learning isn't just about acquiring knowledge — it’s about staying curious, adaptable, and open to new possibilities.
