In a remarkable recognition of his research and development leadership contributions to scientific and innovative technologies, Hongyou Fan has been named the R&D 100 Researcher of the Year for 2025.
This prestigious award, often referred to as the “Oscars of Innovation,” highlights the most significant advancements in research and development across various industries. The selection committee evaluates winners on their previous awards and recognitions, volunteer work, mentorship and other outreach participation.
Hongyou’s work in material science, chemical science, and nanoscience and technologies for sustainable energy solutions has positioned him as a leader in his field.
“Winning this award is not just a personal honor; it reflects the hard work and dedication of my entire team from multiple areas across Sandia,” said Hongyou, who has dedicated more than 25 years to Sandia. “Our mission has always been to address national priorities through innovative research, and this recognition validates our efforts.”
His journey at Sandia began as a postdoctoral researcher in 1997 after completing his doctorate at the University of New Mexico.
“I was very fortunate to stay at Sandia,” Hongyou said. “I received offers from various companies and national labs, but looking back, I believe I made the right choice.”
His commitment to Sandia has led to significant advancements in science, energy and materials sustainability. In 2019, the New Mexico Legislature honored Hongyou as a serial innovator.
In 2022, Hongyou was recognized by the Society of Asian Scientists and Engineers with their Career Achievement Award, which celebrates outstanding contributions to science and engineering. This accolade further solidified his reputation as an R&D leader in his field. In 2025, Hongyou was selected as a Fellow by the National Academy of Inventors.
Hongyou’s current role as a manager for the Geomechanics and Geochemistry Department involves overseeing critical programs that align with national priorities. He has played a pivotal role in establishing Sandia’s critical minerals program, which focuses on advancing science and technologies for recovering essential resources like lithium and rare earth elements.
“The goal is to build a domestic supply chain for critical minerals using our natural resources,” Hongyou said. “By 2035, DOE aims to have 50% of our critical mineral supplies sourced domestically.”
The R&D 100 award is particularly significant as it highlights the impact of Hongyou’s work on both national and global scales.
“Our research is not just about understanding the science of materials; it’s about applying that knowledge to solve real-world problems,” he said. “For instance, our work on lithium recovery from brine sources is crucial for the development of batteries and renewable energy technologies.”
Hongyou’s dedication to scientific advancement is evident in his collaborative efforts with various teams at Sandia. He has led projects that explore the molecular and nanoparticle behavior of materials under extreme conditions, which has contributed to breakthroughs in material science and has been recognized with the Materials Research Society Medal. The Materials Research Society is a group of professionals that promotes communication for the advancement of interdisciplinary materials research and technology to improve the quality of life. Hongyou was recently elected to the board of directors where he will take on another leadership role for the broader scientific community.
“We study how nanoparticles interact under pressure, which can lead to the discovery of new materials with unique properties,” he said. “This research is essential for creating more efficient energy storage solutions.”
The recognition from R&D 100 is a testament to the importance of Hongyou’s work in the context of national security and energy independence. As the U.S. seeks to reduce its reliance on foreign sources of critical minerals, the program he leads provides a pathway to harness domestic resources sustainably.
In addition to his research accomplishments and leadership, Hongyou is also committed to mentoring the next generation of scientists. He encourages young researchers to pursue their passions and remain patient in their endeavors.
“Science is a long journey, and it’s essential to stay focused and persistent,” he advised. “Many breakthroughs take years of dedication, and it’s important to believe in the work you are doing.”
Hongyou’s recognition as the R&D 100 Researcher of the Year is not only a personal achievement but also a reflection of Sandia’s commitment to innovation and excellence in research. His leadership and vision have inspired many within the laboratory and beyond.
“I am proud to be part of a team that is making a difference in the world,” he said. “Together, we are addressing some of the most pressing challenges facing our society today.”
Hongyou accepted his award at the R&D 100 ceremony on Nov. 20, saying that he remains focused on the future.
“This award motivates me to continue pushing the boundaries of what is possible in our field,” he said. “I look forward to the challenges ahead and the opportunity to contribute to a sustainable future for our planet.”
