Micron School of Materials Science and Engineering News
Dr. Lan Li, is an assistant professor in the Micron School of Materials Science and Engineering. She is leading several projects in collaboration with the Idaho National Lab (INL) through the Center for Advanced Energy Studies (CAES,) a public research center focused on collaboration that inspires innovation, fueling energy transitions, and economic growth for the future.
Partnering with CAES allows Boise State researchers to team with INL and other Idaho universities to improve security and quality of life through advanced energy and environmental technology research. One of the current collaborative projects is the In-Pile Instrumentation Initiative. A goal of this initiative is to create and test advanced sensors that can reliably deliver data from inside the extreme environment of a nuclear reactor.
Energy Efficiency through Computational Modeling
Dr. Li’s materials theory and modeling research group uses computational modeling to accelerate the development of new materials for electronic and energy applications. Computer generated models provide a unique opportunity to study the behavior of a material, often on the scale of individual atoms, allowing researchers a powerful view of a material’s structure and potential for use. Researchers can use this data to strategize in-laboratory experimentation, expedite results, and reduce the cost of research and development.
One of the In-Pile Initiative challenges is to design a thermocouple – an electrical device consisting of two dissimilar metal wires, joined at one end. It produces a temperature-dependent voltage as a result of the thermoelectric effect. The voltage can be interpreted as a sensor for measuring temperature. Dr. Li’s team uses computational modeling to predict how various thermocouple elements might respond to extreme environments. The goal is to design a thermocouple that can withstand high temperatures and radiation while maintaining device performance. In analyzing potential materials and designs, Dr. Li also works with other researchers who are experimenting with optical fibers as another potential sensor material. Through modeling, they are identifying designs for specific optical fibers that could meet the performance requirements necessary for use in nuclear reactors.
Computational modeling is also being used to customize the structures and properties of materials for printed in-pile sensor devices. Dr. Li is coupling atomic and microstructure modeling to reveal how specific elements interact during the printing process. This multi-scale modeling approach helps determine how well a device such as a thermocouple, neutron flux foil, or melt wire will perform in an environment where high temperatures, corrosion, pressure, and fission gas can destroy most devices.
Collaborations with the Idaho National Laboratory and the Center for Advanced Energy Studies allow researchers across Idaho’s universities to combine their expertise to find solutions to enhance clean energy. “The sensor projects with INL and CAES leverage my group’s expertise in computational modeling. We are coupling our own developed computational models with INL’s developed nuclear fuel performance codes such as MARMOT phase field and BISON finite element codes,” says Dr. Li. “Partnering in this manner strengthens our nuclear materials and system research abilities. I am pleased to have the opportunity to work with several other Micron School of Materials Science and Engineering faculty to continue our partnership with INL to help meet the world’s energy demands.”

Rebecca was invited to interview for an internship at Boeing through SWE. Her interest in the aerospace field was fueled further by hearing industry members speak at on-campus seminars. Dr. Diane Chong, now retired vice president of research and technology in the Boeing Engineering, Operations, and Technology organization was one of the industry influencers Rebecca was fortunate to have met during a campus visit. Dr. Chong’s presentation on materials selection for the Boeing 787 aircraft resonated with Rebecca. “I have no doubt that my interactions with Dr. Chong directly influenced the rest of my career.”
Finding a Career Trajectory
A few years have passed since Rebecca’s first internship at Boeing. Following this great opportunity to explore Boeing, Rebecca was sure she wanted to pursue a career in the aerospace industry. In fact, her first position after graduating from Boise State was with Boeing, at NASA Marshall Space Flight Center. In this position, Rebecca worked on friction stir welding of aluminum lithium alloys for cryogenic fuel tanks for rockets. Some of the equipment she helped qualify will be producing tanks for the space launch system at NASA Michoud Assembly Facility. Since then, she has remained at Boeing where she continues to thrive. “There are so many different opportunities at Boeing and it is a great place to work,” Rebecca noted. She currently works as a bearings and wear technology engineer supporting the design and manufacturing of the new Boeing 777X aircraft. A routine work day involves drawing reviews, communicating with suppliers, troubleshooting manufacturing issues, and consulting on new design options. Specifically, Rebecca has focused on material selection and design for the folding wing tip hinge and locking features. She has also been involved in the overall design for anything from the flaps, horizontal pivot bearing, engine mounts, landing gear, stowbin fittings, and even a heads up display unit in the cockpit. Prior to the 777X project, Rebecca worked on standards development and qualification for bearings and was also involved in research and development for new wear materials.
Making an Impact
“My journey to a bachelor’s degree helped me identify a lucrative career path,” Rebecca says. “The Micron School of Materials Science and Engineering really focuses on student success and involvement in the materials research community. I had the fantastic opportunity to attend The Minerals, Metals, and Materials Society (TMS) annual meeting in New Orleans with several students and faculty during my time at Boise State. That was a trip to remember.” Looking back on her Boise State experience, Rebecca acknowledges the importance of being involved in extracurricular activities that support success. She especially enjoyed volunteering for outreach activities such as engineering camps and demonstration days. “Making an impact with the next generation has always been important to me. I still mentor and volunteer at university of Washington,” Rebecca notes. She continues her mission to promote materials science and engineering by serving as the chair of the Puget Sound chapter of ASM International.
“I had already chosen engineering as my field of study when I came to Boise State but I really wanted to further my education in physics and chemistry as well as engineering,” Rebecca says. “Amy Moll convinced me that materials science and engineering was the career path for me, I mean, she’s Amy Moll! Because materials science and engineering includes elements of physics, chemistry, and engineering, I was able to remain in all of those fields.” On top of her already challenging schedule of classes and professional development activity, Rebecca played the baritone horn in Boise State’s Keith Stein Blue Thunder Marching Band and in the All-Campus Concert Band. She was a member of Kappa Kappa Psi, the honorary band organization. She also gained some hands-on engineering experience with the Boise State AeroDesign Team that builds unmanned, remote-controlled aircraft for competition.
Rebecca’s career path seems idyllic. It might even seem perfect to most aspiring graduates. Rebecca acknowledges that her success is the result of hard work, active participation. “I highly recommend that students take advantage of the unique opportunities around them in the Micron School of Materials Science and Engineering. Doing so will give them a significant edge in their careers and lives.”
Yaiza Rodriguez was raised in the small city of Esplugues de Llobregat, Barcelona. Growing up, she enjoyed participating in sports and specialized in basketball. She was also an avid gamer. Yaiza’s father introduced her to the world of technology through his work in computer repairs. He had an extensive collection of technology magazines that Yaiza spent countless hours exploring. She also watched with curiosity as her father dismantled, repaired, and assembled a variety of computer systems on a daily basis. It is not surprising that Yaiza was interested in continuing her education in a related field where she could use technology to transform the future.
Excellence in Academics and Athletics
With a broad career goal of making the world a better place, Yaiza knew a college degree would contribute significantly to her success. She also knew she wanted to continue playing basketball, a sport in which she excelled. In fact, Basketball was how Yaiza discovered Boise State University. She was a top recruit who had won three gold medals in championship tournaments in Europe. Yaiza was offered a full scholarship to play on the Boise State Women’s Basketball team. Thrilled to accept the basketball scholarship, Yaiza planned to major in chemical engineering but did not find it as an option at Boise State. After meeting with great advisors in the College of Engineering Advising Center, Yaiza found that what she really wanted was a major that combined her interests in chemistry, physics, and math. Materials Science and Engineering was a perfect match. “I decided to try Materials Science and I ended up loving it,” Yaiza reported.
For many student athletes, an engineering curriculum can be challenging. Team obligations are time consuming and engineering requires some advanced concepts in chemistry, physics, and math. To coordinate a challenging athletic schedule and complex field of study, Yaiza strategized. She intentionally got involved in research after she had much of her coursework completed and toward the end of her basketball scholarship. Planning her Boise State experience allowed Yaiza to excel in academics and basketball simultaneously. In fact, through hard work and dedication Yaiza even earned two minors in her other fields of interest: mathematics and physics, all while participating in daily basketball practices, tournaments, and team activities. During her time on the team, Boise State won two Conference Tournaments and appeared twice in the NCAA Tournament playing against Tennessee and UCLA. Yaiza was a solid team asset. She broke the University’s records in single season assists (192 assists) and carrier assists (a total of 616 assists) and received the Academic All-Mountain West award all four years of her Boise State basketball career.

Sterling Croft traveled across the U.S. from Boston, Massachusetts to attend Boise State University. At 25 years of age, he was intent on making a good decision about which university to attend. Seeking a more affordable cost of living and manageable higher education costs, Boise, Idaho rose to the top of the Sterling’s list. “Living in Boston nearly broke the bank,” Sterling said, “I had to find a more affordable place to earn my degree. Boise State’s reputation as a great engineering university was a big attractor.”
Discovering Materials Science and Engineering
Before enrolling at Boise State, Sterling served a 2-year mission for his church and then worked full-time for a few years to support his family. He had attended college briefly, between working and serving on his mission, but his ultimate goal was to get a college degree. Growing up, one of Sterling’s role models was his father, an electrical engineer. Sterling found an interest in science based on his father’s work, but had not yet found an area of expertise that resonated with him. He had an “aha” moment after attending a lecture presented by Dr. Peter Mullner, distinguished professor in the Micron School of Materials Science and Engineering. “It seemed like the perfect blend of chemistry, structure, and engineering so I became a materials science and engineering major and haven’t looked back,” Sterling says, “Being a part of the Micron School of Materials Science and Engineering is exciting because it has a strong reputation in academics and especially because of the great research opportunities made available to undergraduates.”
Sterling is spending his final semester at Boise State finishing up his course requirements and conducting research in Dr. Claire Xiong’s Electrochemical Energy Materials Laboratory. Sterling works with a team of undergraduates, graduates, and researchers to study sodium-ion batteries and potential additives that could increase their stability and performance. Sodium-ion batteries could have significant impact on future electrochemical energy storage systems. Sodium is widely available and relatively inexpensive to produce in comparison to lithium, which is currently used to create long-life energy storage solutions. While lithium-ion batteries have transformed the industry of portable electronics (cell phones, laptop computers, etc.,) meeting larger application demands like supplementing the power grid and filling gaps in wind and solar power production present greater challenges. Rechargeable batteries allow load-leveling and the shifting of intermittently generated energy from wind turbines and solar panels. These techniques provide on-demand electricity, making green energy solutions more viable for widespread use. Ultimately, rechargeable sodium-ion batteries could provide more efficient and cost effective methods for storing and using energy across the globe.
Sterling recognizes his unique opportunity to conduct hands-on lab research as an undergraduate student. One of his recent projects involved assisting Ph.D. Candidate Pete Barnes in his research on developing an electropolishing process to produce a uniform surface finish on niobium and titanium metals. These metals are used as substrates to grow electrochemically nanostructured metal oxide anodes for the batteries, so the quality of their surface finish affects battery performance. This electropolishing process is now regularly used in the lab with excellent results. “Being in the lab and conducting research is vital to understanding how materials science can influence positive change. I have learned so much more by working with a research team and I feel well prepared to make great contributions in industry,” says Sterling.
Continuing the Journey to a Great Career
After completing his degree requirements and gaining valuable hands-on research experience, Sterling has reached a milestone. He graduated from Boise State with a Bachelor of Science in Materials Science and Engineering in May 2018. He has always worked 20-30 hours per week while taking classes to pay for his education. “The road to achieving a degree has been challenging, but worthwhile. I plan to work as an intern immediately after graduation to gain some industry experience,” Sterling reports. Many great career paths are available to Sterling now that he is obtaining a degree from the Micron School of Materials Science and Engineering. He is considering graduate school in the future but admits that a full-time career that comes with a full-time salary is very appealing after his hard work and dedication to higher education.
Kiyo Fujimoto was born and raised in Idaho. She began her pursuit of higher education right here at Boise State University. She received a Bachelor of Science in Chemistry in 2016 and then recognized that an even higher level of education would greatly contribute to her future success. Kiyo’s ultimate career goal is to help create a greener world. Now that she is pursuing a Ph.D. in Materials Science and Engineering and is a member of Dr. Dave Estrada’s Advanced Nanomaterials and Manufacturing Laboratory team, Kiyo’s goal is becoming reality.
A Vision for the Future
“I envision a world where individuals are able to come together to preserve the Earth’s natural resources to ensure that current and future generations have access to clean air and water,” Kiyo says. She plans to pursue a career as a research scientist so she can influence technological developments that will improve methods of producing energy for worldwide consumption.
Fellowships Provide Real World Experiences
Kiyo recently received a prestigious fellowship from the Idaho National Laboratory (INL), the nation’s premier nuclear science and technology laboratory. Through this fellowship program, INL introduces students to the laboratory and allows them the opportunity to conduct research to fulfill thesis requirements. The benefits are significant for all who are involved. INL receives skilled researchers and cultivates long-term collaborations with universities while students receive valuable research experience in a real-world environment. Boise State and INL collaborate on joint publications and intellectual property developed through the fellowship program.
Kiyo’s research focuses on the use of additive manufacturing techniques such as aerosol jet or 3D printing. Using these methods of printing allows researchers to develop advanced sensors that can remotely track real-time data within a nuclear reactor. Reactors operate at extremely high heat that can damage or destroy sensor equipment. Remote sensors that withstand these extreme conditions can safely monitor a reactor’s performance from any location. Solutions like this address technology gaps as the nuclear industry moves from analog to digital technology. They can also reduce the cost associated with maintaining older nuclear energy systems. “Kiyo Fuijimoto is most deserving of this prestigious award,” said Dr. Estrada “Her success comes as no surprise to those who know and work with Ms. Fujimoto. She is an excellent researcher who has taken a lead on the Boise State campus to establish additive manufacturing as a method to develop advanced sensors for extreme environments.”
Kiyo’s INL fellowship allows her to focus on the coursework necessary to contribute to hands-on research. Once coursework is completed, she will carry out the final two years of her research in-residence at INL in Idaho Falls. The fellowship pays her tuition during these two years, plus a $60,000 annual salary. The opportunity to work on-site at a nuclear research facility allows Kiyo to collaborate with like-minded researchers to reach common goals. “With this kind of collaboration, my graduate experience will be one-of-a-kind,” Kiyo says. The INL fellowship is the second award Kiyo has received for her research in the energy sector.
In 2016, Kiyo’s doctoral project was selected for a three-year fellowship from the Department of Energy’s Nuclear Energy University Programs (NEUP). She was one of only 32 engineering and science graduate students nationwide to be selected for the prestigious fellowship that year. The award provides $50,000 per year, plus $5,000 toward a summer internship at a U.S. national lab. This NEUP Fellowship helped Kiyo build a solid research foundation that she continues to develop through her current INL fellowship.
