Buliding an innovation pipeline though partnerships The Value of Sandia’s Academic Programs & University Partnerships Network

University partnerships play an essential role in sustaining Sandia’s vitality as a national laboratory, and the Sandia University Partnerships Network (SUPN), an element of Sandia’s Academic Programs, facilitates recruiting and research & development collaborations with dozens of universities annually. The Academic Programs umbrella encompasses SUPN, the Faculty Loan Program for Joint Appointments, and the Postdoctoral Research Program Office. The largest branch of Academic Programs is SUPN, which establishes and cultivates strategic academic partnerships that are mutually beneficial. The focused set of schools in the university partnerships network

have expertise complementary to that of Sandia and can help amplify access to a diverse and innovative talent pipeline. In concert, Sandia can accelerate technology transfer via partnerships, increase the potential for partnership impact, provide joint funding to seed strategic research, and enable opportunities for advisory board memberships, faculty sabbaticals, and the exchange of staff, faculty, students, and postdoctoral appointees. In addition to engagement with university leadership and faculty, SUPN strives to establish and sustain strategic research partnerships by establishing and supporting federally sponsored collaborations and multi-institutional consortiums

2021-2022 Collaboration Report

Growing research and talent through partnerships In 2021, the Sandia University Partnerships Network (SUPN) was created. The structure of SUPN includes two categories: Alliance Partners and National/Regional Partners. The goal of the new structure is to establish and cultivate enduring strategic and mutually beneficial relationships with a focused set of schools. The structure provides Sandia with numerous avenues for accomplishing mission and talent pipeline objectives. Under the new university partnerships network, a balanced selection of universities was chosen based on academic standing, strategic research directions, pipeline diversity, ability to attract and retain alumni, and geographic diversity. This approach allows Sandia to partner broadly with universities while investing corporate resources at a level commensurate with the expected partnership impact. The SUPN Alliance Partners category includes schools previously known as Academic Alliance schools (including the Georgia Institute of Technology, Purdue University, University of Illinois Urbana-Champaign, University of New Mexico, and The University of Texas at Austin). Joining these five as new SUPN Alliance Partners are Texas Agricultural and Mechanical University, and the University of California, Berkeley. The SUPN National/Regional Partners category includes 20 schools across the country representing various areas of expertise complementary to that of Sandia. Half of these academic partners are minority-serving institutions, and five of them are part of Sandia’s Securing Top Academic Research Talent (START) at Historically Black Colleges & Universities (HBCU) Program. Each school in the National/Regional Partnership helps Sandia execute top research and facilitate diversity goals. “Sandia is excited by the opportunity to partner with these distinguished institutions. Our nation will continue to reap the rewards of the strong academic collaborations far into the future,” said Deputy Chief Research Officer Basil Hassan.

UT Austin and Purdue LDRD collaborations lead to NASA awards

Research initiated at UT Austin, Purdue, and Sandia led to three NASA University Leadership Initiative (ULI) awards totaling $14.8M. The teams, chosen by NASA, will explore innovations in areas of aeronautical research. The three projects focus on various aspects of autonomous research. Emission & Absorption Spectroscopy Sensors for Hypersonic Flight Control This 3-year, $3.5M ULI award to Purdue resulted from their collaboration on Sandia’s A4H LDRD Mission Campaign. The project will focus on the development of novel in-flight and ground measurement techniques for hypersonic flight. The optical and laser sensor capabilities developed through the A4H project will be used to examine the surfaces and flow of hypersonic vehicles.

Autonomous Aerial Cargo Operations at Scale This 4-year, $8M ULI award to UT Austin came about through three UT Austin PhD students working on Sandia’s Autonomous Detection and Assessment with Moving Sensors (ADAMS) Laboratory Directed Research & Development (LDRD) project. Sandia will continue to collaborate on this work and serve on the Technology Recipients Board for the ULI project. FAST: Full Airframe Sensing Technology for Hypersonic Aerodynamics Measurements This 3-year, $3.3M ULI award performed at UT Austin will enable high-fidelity aerothermal simulations of hypersonic vehicles. Work done on Sandia’s Autonomy for Hypersonics (A4H) LDRD Mission Campaign led UT to focus on creating a new paradigm in sensing for hypersonic vehicles that could also be applied to lower-speed craft. Sandia will collaborate on this work by providing expertise in hypersonic vehicle air flow simulations.

Students who worked on LDRD projects supported through university partnerships supplemental funding in 2021 were invited to present their research at several virtual poster sessions hosted for SUPN Alliance Partners last year. This talent pipeline-focused activity allowed students to showcase their work in a larger forum for their schools and demonstrate their contributions to Sandia research. Andre Claudet, Sandia’s campus partnership manager (CPM) for Georgia Tech, said, “This event has a twofold benefit. It highlights the amazing student work enabled through contributions by our Alliance Partners while also conveying the breadth of problems being addressed by Sandia’s LDRD projects.” Nadine Miner, Sandia’s CPM for UT Austin, added, “By hosting this type of event, we’re also opening up the possibility for new partnerships beyond the initial projects the students are presenting on. It enables attendees to learn about projects and see opportunities for tangential collaborations.” Each student had five to 15 minutes to present their work with a moderator helping to feed them any questions coming through the chat. Students were also invited to sign up for Sandia’s Yello Talent Community list, allowing them to get more information on Sandia career opportunities and be be alerted to any Sandia-hosted events at their schools. Academic Programs Senior Manager Diane Peebles is a strong supporter of these talent pipeline events. She said, “These sessions make student researchers the stars. The supplemental LDRD funding may facilitate the collaboration, but their hard work and insight is an essential ingredient to many projects. We want to further student careers while furthering Sandia missions. ” Poster sessions highlight student contributions to Sandia projects

What would it be like as an undergraduate or graduate student to work alongside some of the world’s leading experts in nanoscience? Approximately a dozen interns from across partner universities can answer that question after participating in the 2021 Center for Integrated Nanotechnologies (CINT) Summer Research Program. In this collaborative, multidisciplinary environment, interns at the Department of Energy funded facility received hands-on experience for eight weeks in areas that explore the path from scientific discovery to the integration of nanostructures into the micro- and macro-worlds. CINT is co-located with Sandia, so students who participate get a sense of just how large Sandia’s campus is and understand the dynamics of working at a national lab that’s a hub of innovation for the nation. Nicole Person, who was a Materials Science & Engineering undergraduate student from Texas A&M University at the time of her internship, said she gained valuable experience from participating in the 2021 program. “I wasn’t completing random technical tasks with no bigger meaning; I was able to sit down with internal and external mentors, understand the specific problem, and then be a part of the discussion on how to best solve the problem. ” During her internship, Nicole said she felt like a “real” scientist in the sense that she was treated and trained like a valuable member of the team and not just some college kid brought on for the summer. She noted, “The lab and public speaking experiences I gained were also extremely helpful for my college career, and I find myself less nervous to do certain tasks because I’ve already done something similar at CINT.” Summer interns learn about the small world at CINT

Electrical engineering students Alyssa Bradshaw, Adia Radecka, and Javi Cardenas conducted experiments at Grainger College of Engineering at Illinois to identify biomaterials that could make effective robotic actuators for implantable medical devices.

Students from across the country benefit from Sandia’s TracerFIRE cyber training TracerFIRE program trains top university talent There isn’t a company or facility across the nation that doesn’t need cybersecurity professionals and systems, and the same is true for the national laboratories. That’s one reason why the TracerFIRE training program takes Sandia experts from Cyber Security Technologies, Cyber Assurance, Cyber Enterprise Security, and Cyber Security Initiatives outside of the laboratory to teach students the basics of computer science and cybersecurity. In 2021 and 2022, Sandia led numerous high-energy, hands-on TracerFIRE events throughout the country with several hosted by SUPN Alliance or National/ Regional Partners. The TracerFIRE team is increasing its START HBCU outreach programs to further develop a diverse STEM-related pipeline, mainly in cybersecurity, to transition undergraduates to masters programs and bring knowledgeable interns/staff to multiple critical areas at Sandia. In 2021, the TracerFIRE team, in collaboration with START HBCU, ran three cybersecurity workshops. In February, the first two-and-a-half-day cybersecurity workshop was held for 40+ students at Prairie View A&M University, Texas A&M, Texas A&M Corpus Christi, University of Texas (UT) Dallas, UT Austin, and The University of Texas at El Paso (UTEP). This workshop used TracerFIRE 10 to simulate state government infrastructure. In March, a workshop was held for North Carolina Agricultural and Technical State University (NC A&T), Highpoint University, University of North Carolina (UNC)- Wilmington, UNC-Greensboro, and Eastern Carolina students. Over 25 students across all schools participated. In April, NC A&T hosted an event attended by an event attended by students from NC A&T and UTEP.

Another TracerFIRE event in August 2021 allowed engineering and computer science undergraduate students from New Mexico State University, New Mexico Institute of Mining and Technology, UNM, and Eastern New Mexico University to investigate advanced persistent threat style adversaries throughout the simulations. The event gave insight into how to recognize adversarial tactics within the kill chain such as reconnaissance, attack vector, exploitation and exfiltration. In October 2021, more than 50 participants engaged in a TracerFIRE event at Purdue to teach students to investigate multiple advanced persistent threat adversaries in a simulated incident response scenario. Other participating schools included Norfolk, Pacific Northwest, and Illinois. Two teams from Illinois traveled to Purdue for the event, with Illinois Director for Research Don Takahara joining as an observer seeking to bring TracerFIRE to his campus in the future. The annual TracerFIRE challenge at Purdue in March 2022 focused on cyber forensics and security. In partnership with the Purdue Center for Education and Research in Information Assurance and Security (CERIAS), Sandia led the Spring 2022 Symposium, which used TracerFIRE 11 to teach thirty-nine students in a challenge exercise on a voter fraud scenario.

Novel approach to producing thin films

CONTRIBUTOR Spotlight

Sandia postdoctoral appointee Robynne Paldi, jumpstarted her research at Sandia through the Labs’ Diversity Initiative. While in the program, she helped develop a fabrication method for epitaxial lithium niobate thin film, useful in SAW devices and radio frequency sensors. This work resulted in a patent, which was developed through a Purdue and Sandia collaboration. “As a postdoc at Sandia, I hope to develop the capability of vertically-aligned nanocomposites and see it used in national security applications,” said Paldi.

High quality thin films are an attractive material for electronics and other devices due to their flexibility and other properties that manufacturers find valuable, but they can be difficult to grow and produce. Haiyan Wang, the Basil S. Tuner Professor of Engineering in Purdue’s College of Engineering, developed a new approach to creating these thin films and was supported through an LDRD at Sandia led by Aleem Siddiqui, an expert in micro-electromechancial systems or MEMS, a miniature machine with both mechanical and electronic components. The team’s approach was to create a single-layer film through a nanocomposite-seeded approach . The optimized and grown lithium niobate (LNO) thin films were further developed for the purpose of surface acoustic wave (SAW) devices that transduce electrical energy to mechanical energy. Sandia postdoctoral appointee Robynne Paldi, who obtained her PhD at Purdue, helped lead the research. She said, “Our films are grown through a pulsed laser deposition method and growth conditions are optimized to achieve high-quality films that can be easily integrated into devices.” The technological approach for these single-layer LNO thin films was ultimately patented .

A new approach to creating popular thin films used for devices was created at Purdue and supported by a Sandia LDRD project.

Moving target defense for space systems

CONTRIBUTOR Spotlight

Christopher Wright is a full time staff member in Sandia’s Strategic Cyber Development organization, but his journey began in the Sandia Extended National Security Externship (SENSE) program. The SENSE internship allows Sandia-employed students to execute a range of research projects throughout the academic calendar on the Purdue campus. Wright is a strong proponent of SENSE. “As a SENSE intern, I applied my knowledge working on real-world problems which

A project, funded by Sandia’s Science and Technology Advancing Resilience for Contested Space LDRD Mission Campaign, developed a patented moving target defense (MTD) algorithm that adds cyber resilience to space systems by improving their ability to withstand cyberattacks. MTDs create dynamic, uncertain environments that seek to confuse the attacker and attempt to defeat cyber threats. Most proposed cyber resilience solutions focus on or require detection of threats before mitigations can be implemented, a significant technical challenge. The new MTD approach avoids this requirement while creating informational asymmetry that favors defenders over attackers. Researchers conducted three key experiments: i.e., functional, cyber resilience, and machine learning (ML), which helped quantify the benefit of the LDRD team’s approach to cyber resilience against different types of cyberattacks. Results show a 97% reduction in adversarial knowledge on a MIL-STD-1553 network. A collaboration with Purdue using ML to defeat the MTD algorithm highlighted the strength of the algorithm by showing a small change in one of the algorithm parameters substantially decreased the success rate of the long short-term memory machine learning model. Further, the generalizable algorithm led to Sandia working with a small business that plans to use this technology to mitigate ransomware and disseminate MTD technology for the U.S. government.

Sandia’s first outbound Faculty Loan joint appointee

Jonathan Pegues, a researcher in Sandia’s Coatings & Additive Manufacturing department, was approved to be the first formally approved Sandia outbound Faculty Loan joint appointee. Pegues’ joint appointment is an agreement between Sandia and Auburn University’s (AU) National Center for Additive Manufacturing Excellence (NCAME). The NCAME is a collaborative effort among AU, NASA, ASTM International and EWI that works to close the standardization and workforce development gaps in additive manufacturing through effective coordination of industry, government, academia, non-profit organizations, and ASTM committees. Pegues is not new to the standards arena. He currently serves as Secretary for the ASTM sub-committee on Additive Manufacturing Applications. In 2020, he collaborated with ASTM International’s additive manufacturing technologies committee to create a proposed standard to rapidly assess the quality of laser beam powder bed fusion (LB-PBF) processes. The proposed standard aims to use off-the-shelf tools to quickly generate qualitative data related to dimensional accuracy and material strength, both of which serve as build health indicators of the machine and the parts. Pegues said the standard he worked on previously for the production of LB-PBF parts for structural applications could potentially be extended to other additive manufacturing techniques. He added, “In this joint appointment position, I’m looking forward to working closely with graduate students to address safety and reliability concerns for fatigue critical additive manufactured parts.”

Jonathan Pegues is Sandia’s first formal outbound Faculty Loan Program joint appointee. He will be working with the National Center for Additive Manufacturing Excellence.

Sandia’s first inbound Faculty Loan joint appointee Sandia’s first inbound Faculty Loan joint appointee, Matt Eichenfield started his career at Sandia in 2011 as a Harry S. Truman Postdoctoral Fellow in National Security Science & Engineering. He then transitioned to a staff member in 2014 and was appointed to the level of Distinguished Staff in 2020. Matt is joining University of Arizona (UA) as an Associate Professor and the inaugural SPIE (the International Society for Optics and Photonics) Endowed Chair in Optical Sciences for UA in August 2022 and will hold an inbound joint appointment with Sandia. Matt will build alignment between Sandia and UA in quantum information, photonic, radio frequency communications, and sensing technologies. While at Sandia, Eichenfield has been an essential part of numerous acclaimed projects. He was tapped to lead a DOE-funded effort at Sandia in 2019 to work on quantum transduction and buffering between microwave quantum information systems and “flying optical photons in fibers,” collaborated with a team that patented a hybrid semiconductor-piezoacoustic radiofrequency device in 2020, and helped to create the world’s smallest and best acoustic amplifier in 2021.

Matt Eichenfield will join University of Arizona as an Associate Professor and the SPIE Endowed Chair in Optical Sciences in August 2022 and will hold an Inbound Joint Appointment with Sandia.

In 2021, Matt Eichenfield and Lisa Hackett were part of the Sandia team that created the world’s smallest and best acoustic amplifier. It is 10 times more effective than earlier versions, and the design and research hold promise for smaller wireless technology.

About the Postdoctoral Research Program Office

The Postdoctoral Research Program Office was inaugurated at Sandia in November 2020 with the purposes of nurturing the next generation of researchers in science and engineering, infusing Sandia’s research enterprise with new ideas and energy from early career researchers, and preparing postdocs for their next career step. Since launching, the Postdoctoral Research Program Office has formalized processes around Foundation Fellowships, managed the Distinguished Fellowships process, and created individualized development plans for Standard Postdoctoral Appointments. The new Program Office has increased postdoc visibility through regional competitions, helped to advance postdoc professional skills, and fostered more engagement through the postdoctoral researchers community at Sandia. Postdoctoral Research Program Office lead Tracie Durbin said, “If a postdoctoral scholar has a successful experience at Sandia, there are three likely outcomes. One, they become fully engaged staff members if they hire on at Sandia; two, they potentially become research partners if they work outside the Labs, or three, they act as ambassadors when discussing their experience with others. No matter the result, it’s a win-win for everyone involved.” A postdoctoral scholar (“postdoc”) is an individual holding a doctoral degree who is engaged in a temporary period of mentored research and/or scholarly training for the purpose of acquiring the professional skills needed to pursue a career path of their choosing. (National Postdoc Association)

Postdoctoral researcher Martha Gross, who is now working on a new kind of molten sodium battery for grid-scale energy storage, was a first place winner during the 2019 Postdoctoral Technical Showcase. 2022 Technical Showcase winners from Sandia-CA and Sandia-NM will compete in the upcoming Bay Area Research SLAM or the Rio Grande Research SLAM.

Inaugural Bay Area Postdoc Research SLAM is a slam dunk Twelve postdoctoral researchers from national labs took the virtual stage on October 28, 2021 to compete in the inaugural Bay Area Research SLAM. Sandia’s three participants, Nicole Jackson, Josh Rackers, and Jennifer Loe, all agreed that the biggest challenges to the competition were the use of one static background slide, a strict 3-minute time limit, and no props to accentuate key points.

“We’re adding our mixed-precision refinement solver to Sandia’s widely used Trilinos library for use by scientists everywhere.”

Josh Rackers from the Computational Multiscale department focused on how he and his team trained a neural network to make accurate predictions on larger sets of water molecules

Former Secretary of Homeland Security Janet Napolitano served as master of ceremonies for the Bay Area Research SLAM competition, which was judged by executives from Sandia, Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory and SLAC National Accelerator Laboratory.

using a much smaller fragment through an approach fusing physics and artificial intelligence. “Electron density is key,” he said. “If we can learn the electron density for water, we might be able to do it for whatever molecule causes the next pandemic.” Jackson, who works in energy water systems integration, spoke on her team’s multilab effort to correlate extreme weather impact data gathered from the 800 sites in Sandia’s Photovoltaic Operations and Maintenance Database. “This presents a new way of fusing together a lot of disparate datasets and could provide us with the ability to improve resiliency to extreme weather and gain energy output at solar energy sites,” she said. Loe presented on the successful results her Scalable Algorithms team received when running 32-bit precision computer simulations while utilizing multiprecision strategies on their GMRES linear solver to take smaller, more frequent steps to refine the high accuracy solution that was needed. “We’re adding our mixed-precision refinement solver to Sandia’s widely used Trilinos library for use by scientists everywhere,” Loe commented.

2022 Distinguished Hruby and Truman Fellows join Sandia

The two Jill Hruby and two Harry S. Truman Distinguished Postdoctoral Researchers started their independent research at Sandia in October 2021. The Hruby Fellows are to “develop advanced technologies to ensure global peace,” and the Truman Fellows are to perform “exceptional service in the national interest.” Sommer Johansen , a 2022 Hruby Fellow, received her doctorate in physical chemistry from the University of California, Davis, and aims to improve models that demonstrate how burning bio-derived fuels affect the Earth’s planetary ecology and severe forest fires caused by climate change during her Hruby fellowship. Johansen is working with the gas-phase chemical physics department, studying gas-phase nitrogen chemistry at Sandia’s Livermore site under the mentorship of Lenny Sheps and Judit Zádor. “ UC Davis is close to Livermore, and the Combustion Research Facility there was always in the back of my mind. I wanted to go there, use the best equipment in the world and work with some our field’s smartest people. ” Alex Downs , a 2022 Hruby Fellow, completed her doctorate at the University of California, Santa Barbara, and wants to create wearable biosensors for long duration, real-time molecular measurements of health markers that would be an ongoing measurement of a person’s well-being. When she saw the Hruby posting on LinkedIn, she thought, “ There’s a huge opportunity here for freedom to explore my research interests. I can bring my expertise in electrochemistry and device fabrication and develop new skills working with microneedles and possibly other sensing platforms. ” Downs’ mentor, Ronen Polsky, is an internationally recognized expert in wearable microneedle sensors, and she is working with Sandia’s biological and chemical sensors team.

Hruby Fellow Sommer Johansen hopes to help improve comprehensive

chemical kinetics models of the after-effects on Earth’s planetary ecology of burning bio-derived fuels and the increasingly severe forest fires caused by climate change.

Hruby Fellow Alex Downs plans to create wearable biosensors that gather real-time molecular measurements. She plans to make the sensors longer lasting by improved understanding of how the sensors are impacted by biofouling in media.
