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."

Climate Change Collaborator

Professor Erin Mayfield was selected to serve as a lead author of the Intergovernmental Panel on Climate Change (IPCC) Seventh Assessment Report. IPCC is the UN body for assessing the science related to climate change, and Mayfield is one of 664 experts from 111 countries appointed to participate. Assessment reports are published every 5 to 7 years to provide governments with information to develop climate policies, and to inform international negotiations to tackle climate change.

NIH Research Award

Professor Wei Ouyang was awarded a Maximizing Investigators’ Research Award (MIRA) from the National Institute of General Medical Sciences (NIGMS), part of the National Institutes of Health. The award provides $2.2 million over five years to support Ouyang's research on implantable technologies for monitoring internal organ health. His work aims to advance understanding of the pathophysiology underlying post-operative complications and inform the development of safer, more effective interventions.

Advances in Cybersecurity

PhD students Sie Hendrata Dharmawan, Emma Graham, Mateusz Nowak, and Qintong Xie, as well as Roy Leibovitz '27, programmer Edward Koh, and postdoc Xavier Cadet—most in Professor Peter Chin's Learning, Intelligence + Singal Processing (LISP) lab—had four papers accepted into the Conference on Game Theory and AI for Security. "These papers are part of the four-year DARPA research project called CASTLE: Cyber Agents for Security Testing and Learning Environments which LISP lab has been working on to develop game-theoretic reinforcement learning agents that can outsmart potential cyber adversaries in an enterprise-level network," said Chin.
