Pulse Analysis
Dr. Tim Long, a professor of chemistry at Virginia Tech and director of the Macromolecules Innovation Institute, leads a research program that designs novel macromolecular structures to tune polymer properties. By bridging fundamental polymer chemistry with engineering, his team creates materials that can be processed into advanced forms, from drug‑delivery carriers for chemotherapy to electroactive components for prosthetic devices. This interdisciplinary approach reflects a broader shift in polymer science toward customizable, high‑performance materials that address both medical and industrial challenges.
A flagship project in Long’s lab focuses on additive manufacturing of light‑responsive paints, or colloidal latexes, that solidify under patterned illumination to produce three‑dimensional objects with hair‑diameter resolution. By engineering the molecular architecture of the paint, the researchers achieve precise control over curing kinetics, enabling the fabrication of complex geometries previously unattainable with conventional 3D printing. Potential applications range from patient‑specific biomedical scaffolds and wearable sensors to on‑site construction of structural adhesives, illustrating how molecular‑level design can unlock new markets for additive manufacturing.
Long’s career, which includes senior research roles at Eastman Kodak and collaborations with the National Institute of Standards and Technology, underscores the value of industry‑academic synergy. His experience translating laboratory breakthroughs into scalable processes informs his emphasis on rapid idea generation and cross‑disciplinary partnerships—key drivers for commercializing polymer innovations. As businesses seek sustainable, high‑precision manufacturing solutions, the technologies emerging from his group promise to reshape supply chains, reduce material waste, and create differentiated products across healthcare, aerospace, and consumer goods sectors.
Episode Description
Dr. Tim Long is Professor of Chemistry and Director of the Macromolecules Innovation Institute at Virginia Tech. Tim's lab is working on a wide variety of research projects that are focused on novel macromolecular structures to tailor the properties and processing of polymers. His work has applications across many industries, including the development of chemotherapy treatments and electro-active devices important for prosthetics in medicine. In his job, Tim spends a lot of time in his office, in front of computers, in the lab, and inside at conferences, so he likes to spend his free time outside. There are beautiful mountains near his home in Virginia, and Tim has fun hiking, mountain biking, and enjoying nature with his family. He was awarded his B.S. in Chemistry from St. Bonaventure University and his Ph.D. in Chemistry from Virginia Tech. Prior to joining the faculty at Virginia Tech, Tim worked as an Advanced Research Scientist and subsequently a Senior Research Scientist at Eastman Kodak Company, an Advanced Technical Program Research supported by the National Institute of Standards and Technology, and a Principal Research Chemist with Eastman Chemical Company. Tim has received numerous awards and honors over the course of his career, including the Virginia Outstanding Scientist of the Year Award, the Robert L. Patrick Fellowship Award, the ACS POLY Mark Scholar Award, the Carl Dahlquist Award from the Pressure Sensitive Tape Council, the American Chemical Society Polymeric Materials: Science and Engineering (PMSE) Cooperative Research Award, the Virginia Tech Alumni Award for Research Excellence, the Collano Innovation Award, the Interdisciplinary Research Team Fellowship Award, the Faculty Research Award from the Virginia Tech Department of Chemistry, the IBM Faculty Award, and the 3M Company Faculty Award. Tim has also been named a Fellow of the American Association for the Advancement of Science, a Fellow of the American Chemical Society, and a Fellow of the American Chemical Society Polymer Division. In our interview, Tim shares more about his life and science.
