Co-Designing Public Education

Professor Rafe Steinhauer authored "Improving Public Schools by Co-Design," published in the inaugural issue of Dartmouth's Social Impact Review. The article centers on Steinhauer's unique approach to combining design and education. "Our program [Upper Valley Education Design Clinic] prioritizes co-design. Together, district teams and undergraduate students [ENGS 15.11: Design and Education] learn design thinking ... This is an exciting model for town-gown partnership—not just universities serving schools, but higher education and K-12 communities working as co-designers of change," writes Steinhauer.

Predicting Nonadherence to Breast Cancer Screening

PhD student Jiahui Luo and Professor Wesley Marrero—with quantitative biomedical sciences PhD student Guofang Ma and Miranda Scully '26—co-authored "Modeling the impact of social determinants on breast cancer screening: a data-driven approach" published in Frontiers in Medicine. "The study identified opportunities for healthcare organizations to transform sociodemographic data into targeted, facility-level intervention strategies while adapting to payer incentives and addressing screening gaps," said Marrero.

Strategic Cyber Defense

PhD student Mai Pham and professors Vikrant Vaze and Peter Chin coauthored "Strategic Cyber Defense via Reinforcement Learning-Guided Combinatorial Auctions" which was chosen for presentation at the IEEE High Performance Extreme Computing Conference. "This work formulates the cyber defense problem, in which we act as a defense agent protecting a network from malware attackers, as a combinatorial auction," said Pham. "We combined reinforcement learning with differentiable mechanism design to find the best resource allocation for the hosts, which aims to upstream decision making and proactively protect the network."

Toward Greener Batteries

Research Associate Peiyu Wang Th'25, PhD students Huilin Qing and Ruiwen Zhang, and Professor Fiona Li coauthored "Fluorine-free electrolytes for sustainable lithium batteries: a review" published in npj Materials Sustainability. The paper highlights insights and advances in fluorine-free salts, solvents, additives, and interphases, along with challenges and opportunities, offering sustainable solutions potentially competitive with conventional fluorinated electrolytes. "Modern lithium battery electrolytes rely on fluorinated components to enhance performance and functionality, but such schemes raise safety, environmental, and cost concerns due to hydrogen fluoride generation and hazardous production," said Li.

Biology of Human Milk

Goods Lab PhD student Laasya Devi Annepureddy is co-lead author of "Integrated ‘omics analysis reveals human milk oligosaccharide biosynthesis programs in human lactocytes" published in iScience. The study reveals pathways for how breastmilk cells produce sugars that are critical to infant health and development, and paves the way for being able to add them to formula or as a supplement to certain foods. "Being part of this project has been incredibly rewarding," said Annepureddy. "Our findings bring us one step closer to understanding the remarkable biology of human milk, and I’m grateful to the outstanding team whose collaboration made this work possible."

Atomic Neighborhoods in Semiconductors

Professor Jifeng Liu is coauthor of "Identification of short-range ordering [SRO] motifs in semiconductors" published in Science. Using electron microscopy and machine learning models, the study confirmed the presence of semiconductor SRO—where atoms form mini configurations or "neighborhoods" within the material. The concept of SRO has lacked experimental evidence, and this confirmation opens up new possibilities for controlling the properties of semiconductors. "My lab was the first to identify the samples that revealed signs of atomic ordering, and I initiated and promoted the idea that engineering atomic neighborhoods in semiconductors offers a new degree of freedom for controlling their electrical and optical properties," said Liu.

Applications of Liquid Metal Materials

Saifur Rahman Th'25 and Professor Will Scheideler coauthored "Liquid Metals in Radio Frequency Applications: A Review of Physics, Manufacturing, and Emerging Technologies" published in Advanced Electronic Materials. "Liquid metal materials are transforming soft and stretchable radio frequency devices by enabling highly-conductive, mechanically-adaptable components that can conform to wearable and bio-integrated applications," said Scheideler. "This work highlights the physics of energy loss in liquid metal systems, innovative fabrication techniques, and diverse applications."

Broadband Microwave Sensor

Professor Paul Meaney and Research Associate Zamzam Kordiboroujeni are coauthors of "Real-Time Microwave Medical Scanning" published in IEEE Microwaves Magazine. "We have developed a new broadband microwave sensor for detecting and diagnosing subsurface medical conditions such as sarcopenia," states the article. "The device is an open-ended coaxial concept that has been fabricated using 3D metal printing technologies."
