National Hispanic science and engineering organization honors two Sandia researchers

ALBUQUERQUE, N.M. — Materials scientist Nic Argibay and health and safety senior manager Rafael Gonzalez were honored at the 31st annual Hispanic Engineer National Achievement Awards Conference by Great Minds in STEM, a nonprofit organization that recognizes Hispanic leadership and achievement in science, technology, engineering and math.

Argibay received a Most Promising Scientist or Engineer award and Gonzalez received a Luminary award during the society’s annual conference in late September.

HENAAC awards represent Hispanic contributions at high levels of academia, government, military and industry. Luminary honorees are professionals who lead key programs within their companies and who have made significant contributions to the Hispanic technical community as leaders and role models.

Argibay has made significant contributions to the scientific field of tribology, the study of interacting surfaces in relative motion, including the principles of friction, lubrication and wear. He has received more than $7 million in scientific grants and awards leading to groundbreaking discoveries, such as the in-situ formation of diamond-like carbon on platinum-gold substrates and one of the most wear-resistant materials ever tested.

“Ultimately, we developed an alloy that is insensitive to remarkable amounts of temperature and mechanical stress,” Argibay said.

His work with high-entropy alloys, metals that blend similar proportions of several elements, has led to multiple invitations to speak at conferences, colloquia and seminars worldwide.

He currently serves on the board of directors of the Society of Tribologists and Lubrication Engineers, a position he was elected to in recognition of his many contributions to the tribology field and his service to the society.

The son of a computer programmer and a physicist, Argibay moved to Miami, Florida, from Montevideo, Uruguay, when he was 9 years old.

“They sold everything they owned, with the exception of the contents of a few suitcases. My parents were nuts; so courageous. I’m so grateful they did what so many wouldn’t dare to try,” Argibay said.

That same year, Hurricane Andrew, one of the most destructive hurricanes recorded in Florida, struck their new home. His parents were undaunted in starting their new life despite the immediate upheaval.

One of Argibay’s early mentors was a prep school physics teacher who formed a physics club and organized a trip to watch a space shuttle launch. “I remember thinking, this is what I want to spend my life working on,” Argibay said. He pursued a career in aerospace engineering. Unsurprisingly, he is now an airplane enthusiast and has a pilot’s license.

Argibay came to Sandia in 2011, immediately after receiving his doctoral degree in mechanical engineering from the University of Florida, transitioning from a postdoctoral researcher to a permanent member of the research and development staff in 2013.

His manager, Cole Yarrington, said, “Nicolas has also demonstrated, without expectation of recognition, his commitment to giving back to the community through his public school and university outreach.”

This outreach has included coaching a National Science Bowl team and helped high school students craft experiments for a STEM outreach program.

As a child, Gonzalez loved spending time in his grandfather’s carpentry shop, where he gained mechanical skills and learned life lessons that proved equally useful.

“Mi abuelo was the wisest individual that I have ever met, even though he only completed primaria (elementary school),” Gonzalez said. “He taught me that working hard with integrity and doing your best with purpose was the most important thing in life — whether you were a barrendero (street sweeper), engineer or a carpenter like himself.”

His hard work in school paid off when he unexpectedly met the president of the University of Texas at El Paso, who was visiting Gonzalez’s high school to promote a financial assistance program for Mexican students. Gonzalez, who grew up in Chihuahua, Mexico, had wanted to study at an American university but could not afford to do so. The morning after graduation, he took the SAT exam, scoring high enough to qualify for the support and acceptance to UTEP, where he ultimately received bachelor’s and master’s degrees in electrical engineering.

“Rafael is known for his passion and boundless energy,” said Dave Sandison, director of Sandia’s Microsystems Engineering, Science and Applications (MESA) center. “Given that I see how much effort he puts into his work, I’m always amazed (no longer surprised) to learn how much he does in the community.”

Deeply committed to STEM education for Hispanics, Gonzalez initiated the first Noche de Ciencias (Science Night) in New Mexico in 2016, which has led to 800 middle school students participating in science and technology activities and 150 parents attending bilingual workshops.

Gonzalez has served in many community organizations, including the United Way Hispano Philanthropic Society, where he helped establish a mentoring program and the Middle School Initiative Fund for low-income, Hispanic middle school students. He is a past president of the Society of Hispanic Professional Engineers and the New Mexico Society of Professional Engineers. He is currently deputy co-chair of Sandia’s Hispanic Outreach for Leadership and Awareness organization and serves on the boards of directors for New Mexico Mathematics, Engineering and Science Achievement — a group that helps prepare students for college and careers in STEM fields — and the New Mexico Museum of Natural History and Science Foundation.

In 2015, Gonzalez joined Sandia as a research and development manager in MESA, where he oversaw research programs and production operations for radiation-hardened microsystems technologies. His work enabled new and increasingly powerful technology for critical national security programs, the nuclear weapons stockpile and nuclear deterrence. He is currently a senior manager for performance assurance and engineered safety to ensure efficient, effective and safe operations across Sandia.

Sandia National Laboratories is a multimission laboratory operated by National Technology and Engineering Solutions of Sandia LLC, a wholly owned subsidiary of Honeywell International Inc., for the U.S. Department of Energy’s National Nuclear Security Administration. Sandia Labs has major research and development responsibilities in nuclear deterrence, global security, defense, energy technologies and economic competitiveness, with main facilities in Albuquerque, New Mexico, and Livermore, California.
