Three researchers at the Department of Energy’s Oak Ridge National Laboratory have been named ORNL Corporate Fellows in recognition of significant career accomplishments and continued leadership in their scientific fields.
Corporate Fellow is the highest recognition for members of the ORNL research staff. Michael McGuire, Forrest Hoffman and Vlastimil Kunc have been recognized by the laboratory for their standing in the international scientific community as exceptional and influential researchers and as role models and mentors among peers and early career researchers.
“Corporate Fellows epitomize ORNL’s commitment to scientific excellence and leadership," said ORNL Director Stephen Streiffer. "Their outstanding research accomplishments, influential contributions to the broader scientific community, and dedication to mentoring the next generation of researchers are vital to the laboratory’s continued success. Congratulations to Forrest, Vlastimil, and Michael on this well-deserved recognition.”
Forrest Hoffman leads the Integrated Computational Earth Sciences Group in Oak Ridge National Laboratory’s Computational Sciences and Engineering Division. Hoffman has been a leading force in developing and applying Earth system models to study global biogeochemical cycles, including terrestrial and marine ecosystems, and their interactions with the Earth system. His research focuses on evaluating and advancing large-scale environmental models that inform national and international assessments. Hoffman helped establish the International Land Model Benchmarking system, now used globally to compare and validate Earth system model performance.
At ORNL, Hoffman has led several DOE activities, including the RUBISCO Science Focus Area and the ESGF2-US project, securing more than $50 million in competitive research funding during his tenure. Under his leadership, the Computational Earth Sciences Group grew from eight to 19 researchers, strengthening ORNL’s expertise in modeling and data science. He has played a key role in developing next-generation environmental data and modeling capabilities, including leadership of the global Earth System Grid Federation data infrastructure.
Hoffman has published extensively on computational Earth science and is recognized internationally for his leadership in model evaluation and data analytics. A mentor and advocate for interdisciplinary collaboration, he has guided students and early career researchers who now hold leadership roles at ORNL. Through his scientific and organizational leadership, he continues to strengthen ORNL’s role as a national center for environmental and predictive modeling research.
Vlastimil Kunc leads the Composite Science and Technology Section in Oak Ridge National Laboratory’s Manufacturing Science Division, where he has redefined the boundaries of composite materials and large-scale additive manufacturing. An internationally recognized expert, Kunc has helped position ORNL as a global leader in advanced manufacturing innovation, driving breakthroughs in additive and hybrid systems, fiber-reinforced polymers, and composite applications that strengthen U.S. industrial competitiveness.
At ORNL, Kunc has grown the section he founded from three researchers to nearly 60, building one of the world’s foremost programs in composite science and technology. His research has enabled new industrial capabilities across the automotive, aerospace and defense sectors, including the first 3D-printed thermal protection system tested on the International Space Station.
Kunc has authored more than 180 peer-reviewed publications, holds 19 patents, and has earned six R&D 100 Awards, eight CAMX Awards for Composites Excellence, two Federal Laboratory Consortium Awards, the 2023 Battelle Distinguished Inventor honor, and the 2025 ORNL Inventor of the Year award. He also holds a Guinness World Record for producing the world’s largest solid 3D printed item.
Beyond his research, Kunc mentors students and early career scientists and contributes to national initiatives such as IACMI, the Composites Institute and the Department of Energy’s advanced manufacturing roadmaps. Through his vision and leadership, he continues to elevate ORNL’s global reputation, advancing U.S. innovation, strengthening domestic supply chains and expanding the nation’s industrial and scientific impact.
Michael McGuire leads the Correlated Electron Materials Group in Oak Ridge National Laboratory’s Materials Science and Technology Division and directs materials research for the Quantum Science Center. McGuire is recognized for his world-leading research and leadership in materials for quantum and energy technologies, including superconducting, magnetic, two-dimensional and topological materials.
At ORNL, McGuire has helped secure and lead major DOE initiatives — the Quantum Science Center and Critical Materials Innovation Hub — uniting multidisciplinary teams across national laboratories and universities. His work has advanced ORNL’s capabilities in materials discovery and strengthened collaborations that support emerging quantum and energy technologies.
A six-time Highly Cited Researcher with more than 340 publications, McGuire holds six patents and is a Fellow of both the American Physical Society and the American Association for the Advancement of Science. His honors include two R&D 100 Awards, the Gordon Battelle Prize and multiple UT-Battelle Director’s Awards. Widely regarded for his collaborative leadership and mentorship, McGuire continues to advance ORNL’s mission in materials and quantum science.
UT-Battelle manages ORNL for DOE’s Office of Science, the single largest supporter of basic research in the physical sciences in the United States. The Office of Science is working to address some of the most pressing challenges of our time. For more information, please visit energy.gov/science.
