Imagine, November 2025
Dear MatSE friends and alumni,
It’s truly a pleasure to share highlights from one of our department’s most honored traditions, the Nelson W. Taylor Lecture in Materials. Each year, this event brings our community together to celebrate scientific excellence, human stories, and the shared curiosity that drives our field forward. The Taylor Lecture is the most prestigious honor bestowed by our department, and over the decades, it has featured some of the most inspiring voices in materials science, including six Nobel laureates. This year’s theme, “Forging the future of steel,” felt especially meaningful as it connects our Commonwealth’s proud industrial past to the exciting innovations shaping the future.
Steel is more than just a material for Pennsylvania: it’s a core part of our identity. From the mills of Pittsburgh and Bethlehem, which built the bridges, railways, and skylines of America, to the laboratories and classrooms here at Penn State, steel has embodied the strength, resilience, and ingenuity of our Commonwealth. As we look toward a future defined by sustainability, digital manufacturing, and clean energy, the story of steel continues to evolve, and with it, new opportunities to strengthen both our economy and our planet.
This year, we were deeply honored to welcome Sir Harry Bhadeshia as our distinguished Taylor Lecturer. Sir Harry, a professor of metallurgy at Queen Mary University of London and emeritus Tata Steel Professor at the University of Cambridge, is one of the world’s leading experts on iron and its alloys. His lecture, “Diffusion in iron: Sometimes invigorating, at other times lethargic,” offered not only profound scientific insight but also a sense of wonder about how atomic motion can shape the foundation of modern human civilization.
What made Sir Harry’s visit truly special, though, was his personal story. Born in Kenya, he emigrated to the United Kingdom at the age of sixteen, where he built a life of discovery, teaching, and quiet generosity that ultimately earned him knighthood from Queen Elizabeth II. Despite his lofty accomplishments, Sir Harry is the most gracious and humble of scholars: deeply curious, kind, and passionate about sharing his knowledge. He is, in every sense, a role model for our students and an inspiration for all of us who continue to drive the field of materials science forward.
We were also proud to feature three of our own Penn State faculty, each of whom is advancing the science and technology of steel in remarkable ways.
- Amrita Basak, associate professor and Shuman Early Career Professor of mechanical engineering, shared her work on “Data science for additive processing of steel alloys,” showing how artificial intelligence and digital twins are revolutionizing the way we design and build metallic materials.
- Todd Palmer, professor of engineering science and mechanics and of materials science and engineering, spoke on “What is old is new again: New research challenges in the development and processing of stainless steels,” reminding us that even the oldest materials still hold new secrets when viewed through the lens of modern science.
- And Tarasankar DebRoy, professor of materials science and engineering, delivered a presentation on “Welding science powers 3D printing, but can metal supply chains peep up?” which connected decades-old welding science to the cutting-edge world of additive manufacturing while raising important questions about sustainability and global supply.
Together, these talks captured exactly what makes the Taylor lectures so meaningful. As I listened to the presentations and felt the enthusiasm of the audience in the room, I couldn’t help but think of how far we’ve come as a department. The story of steel, like the story of our own Penn State MatSE community, is one of perseverance, innovation, and human connection. We are proud to carry forward that tradition, inspired by those who came before us and energized by the generations of students, researchers, and alumni who continue to make a difference.
Thank you for being part of our Penn State MatSE family. Your support of our core missions in research, education, and service keeps our community strong. Together, we are truly forging the future.
We Are!
