During Sheera Lum’s first week interning at the U.S. Department of Energy’s (DOE’s) Argonne National Laboratory, she wasn’t sure if it would be the right fit. She has interned in industry before but never at a national laboratory, and the terminology in the tribology department was as mystifying as a foreign language.
But by the third week, Lum was sold.
“I definitely want to do research. I hope to pursue a Ph.D. in materials science,” said the mechanical engineering senior from Mississippi State.
Lum was part of the Science Undergraduate Laboratory Internship (SULI) program sponsored by DOE’s Office of Science. During her industry internship the previous summer, she had learned to design hydraulic pumps. At Argonne, she learned how to tie that type of work to her passion for sustainability and optimize biodegradable lubricants to reduce wear and tear on the components of a hydraulic pump.
“This is a great opportunity to do some hands-on experiments rather than just sitting in front of a computer doing modeling,” Lum said.
The interns spend their days preparing samples for testing in grinder-type environments that simulate years of wear on bearings and lubricants. They use microscopes to look for microscopic cracks and the lab’s X-ray machine, the Advanced Photon Source, a DOE Office of Science User Facility, to look for internal defects on the nanoscale.
The field of tribology started in the 1960s and focuses on ways to make materials more energy efficient by reducing friction and wear through design and lubrication, including creating biodegradable lubricants and coatings that are free of harmful additives. Tribology is used in everything from heavy machinery, to contact lens coatings, to next-generation lasers.
Argonne scientists and engineers work with interns as a way of exposing them to what it would be like to work in a national laboratory and in fields they may never have thought about. It takes time for the scientists to train the students, but Maria De La Cinta Lorenzo Martin, a materials scientist who oversees several of the tribology interns, said she views it as an investment. About 25 percent of the interns in the tribology group will decide to go on to get Ph.D.s, and some to return to start careers at Argonne.
Even those who decide to go into industry or other fields pay dividends in the form of fresh perspectives and questions that stir creativity in the Argonne team. Plus, once the students learn about tribology, they take that knowledge with them, allowing them to incorporate it into new applications, such as biologists creating bio tribology for longer-lasting medical implants.
“Exposing students to a variety of career options, scientific disciplines and the diversity of Argonne’s workforce are some of the goals of the SULI program,” said Meridith Bruozas, manager of Educational Programs at Argonne.
Sam Kizlaitis, another SULI intern, spent his previous summers drilling holes at a construction job, but with his transfer from Moraine Valley Community College to the University of Illinois at Urbana-Champaign for chemical engineering, he thought he ought to try to figure out what working in the chemical engineering field would be like. An internship in Argonne’s tribology laboratory has him coating samples with various lubricants and testing them to determine how the physical properties of those coatings and samples change under stress. The goal is to find coatings that reduce wear and extend the life of gears, such as those used in vehicles and wind turbines.
“This internship provides much more insight about my future career,” said Kizlaitis, a junior. “I am able to use stuff that I learned in school in the real world rather than just doing math problems. I’m having fun. I can’t criticize (Argonne) one bit.”
The DOE Vehicle Technologies Office and the Wind Energy Technologies Office funded the tribology projects that the students helped with during the summer.
Argonne has made it a core mission to develop advanced manufacturing technologies, such as advanced coatings, materials with advanced properties and manufacturing processes that are more energy efficient.

The SULI program encourages undergraduate students to pursue science, technology, engineering and mathematics careers by providing research experiences at the DOE laboratories and facilities. Selected students participate as interns appointed at one of 17 participating DOE laboratories and facilities. They perform research, under the guidance of laboratory staff scientists or engineers, on projects supporting the DOE mission. The SULI program is sponsored and managed by DOE’s Office of Science.
DOE’s Office of Energy Efficiency and Renewable Energy supports early-stage research and development of energy efficiency and renewable energy technologies that make energy more affordable and strengthen the reliability, resilience, and security of the U.S. electric grid.
Argonne National Laboratory seeks solutions to pressing national problems in science and technology. The nation’s first national laboratory, Argonne conducts leading-edge basic and applied scientific research in virtually every scientific discipline. Argonne researchers work closely with researchers from hundreds of companies, universities, and federal, state and municipal agencies to help them solve their specific problems, advance America’s scientific leadership and prepare the nation for a better future. With employees from more than 60 nations, Argonne is managed by UChicago Argonne, LLC for the U.S. Department of Energy’s Office of Science.
The U.S. Department of Energy’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time. For more information, visit the Office of Science website.
