Congratulations to Oliver Shao for being awarded the Best Paper Award at the IEEE Conference on Computational Imaging Using Synthetic Apertures

Yunzhe “Oliver” Shao, a graduate student at JILA in the group led by JILA Fellows and University of Colorado Boulder Physics professors Margaret Murnane and Henry Kapteyn, has been awarded the Best Paper Award at the IEEE Conference on Computational Imaging Using Synthetic Apertures.

Shao’s winning research focused on developing an extreme ultraviolet (EUV) reflectometer. This innovative instrument is designed to characterize various nanostructured samples’ chemical compositions and spatial properties.

“This research represents a first-iteration, proof-of-concept instrumentation for nanostructure metrology,” Shao explained. “It has been constructed, developed, and improved over several generations of graduate students in our group. It is reassuring and inspiring to share its new capabilities and witness the interest it generates from the metrology community.”

The paper was submitted to the 2024 IEEE Conference on Computational Imaging Using Synthetic Apertures, created in partnership with and hosted by NIST (the National Institute of Standards and Technology). The annual event highlights advancements in cutting-edge computer imaging and sensing using high-resolution imaging systems, like the reflectometer Shao and the KM group work on.

Shao expressed gratitude for the recognition, highlighting the collective effort behind the project. “Apart from its founding members, whose names are listed in several previous publications, the reflectometer does not exist without the continuing efforts of current students and postdocs from our group, including Nick Jenkins, Clay Klein, Yunhao Li, and Jiayi Liu. We are motivated to further develop and improve this metrology instrument beyond its current limitations.”

Congratulations to Anya Grafov for being awarded the Best Poster Award at the IEEE Magnetics Summer School in Taipei

Anya Grafov, a graduate student at JILA, has been awarded the Best Poster Award at the IEEE Magnetics Society Summer School 2024. Studying under JILA Fellows and University of Colorado Boulder Physics professors Margaret Murnane and Henry Kapteyn, Grafov’s poster titled “Probing Ultrafast Spin Dynamics with Extreme Ultraviolet High Harmonics” was one of only nine to receive this prestigious recognition.

“Winning this award from the IEEE Magnetics Society is an incredible honor. It validates the hard work and dedication put into our research and motivates us to continue pushing the boundaries in magnetics research,” stated Grafov. “Our technique is quite niche, so I wanted to focus my poster on our actual measurement technique and the experiments we conduct. It’s an overview of the measurement technique and examples of two recent projects we’ve been working on using our beamline.”

Highlighting the fundamentals and new research, like Grafov’s, in magnetics, the annual summer school brings together graduate students worldwide to study magnetism through lectures by international experts and poster presentations.

“It was a great experience to learn about different aspects of magnetism, from fundamental research to applied technologies like spintronic devices and magnetic artificial intelligence,” she added.

Congrats to Alex Stevens for Being Awarded a 2023 Whitcome Pre-doctoral Fellowships in Molecular Biology

Biochemistry, Molecular and Structural Biology (BMSB) graduate students Andrew Goring (Clubb/Loo groups) and Alexander Stevens (Zhou group) have been awarded prestigious Whitcome Pre-doctoral Fellowships in Molecular Biology for 2023-24. The fellowship will provide them support in the form of tuition/fees, a monthly stipend and travel funds.

Alex Stevens received his bachelor’s degree in Biochemistry from Arizona State University, where he researched G protein-coupled receptor structures in the lab of Professor Wei Liu. In the fall of 2019, Alex joined the Biochemistry, Molecular and Structural Biology (BMSB) graduate program under the tutelage of Professor Hong Zhou.

Alex’s graduate work leverages the recent advancements in cryo-electron microscopy (cryoEM) to resolve high-resolution structures of the proteins that drive assembly and replication in double-stranded RNA (dsRNA) viruses. Because dsRNA is alien to eukaryotes and thus a powerful inducer of the antiviral response, these viruses have evolved to transcribe nucleotides at transcriptional enzymatic complexes (TECs) within their proteinaceous capsids which simultaneously undergo large architectural changes. Alex investigates this dynamic within complex dsRNA viruses, like the economically important aquareovirus, to determine how their TECs and capsids change throughout their lifecycle. He has also characterized a minimally complex dsRNA virus which he plans to use as a model to probe the rules of intracellular replication amongst these ubiquitous pathogens.

Alex is passionate about deepening our understanding of disease and hopes to contribute to the discovery of therapies that improve people’s lives and wants to improve the manner in which we conduct science so it may realize all its promises to stakeholders. After receiving his PhD, Alex plans to pursue research roles uncovering the mechanisms underpinning pathogenesis of harmful microbes and hopes to one day branch into science policy. “UCLA gave me the perfect environment to collaborate with preeminent scholars, learn techniques from the leading edge of my field, and produce impactful work, and I look forward to applying what I’ve learned to my future work.”

About the Whitcome Fellowships

In 2005 UCLA received an $8,000,000 bequest from the estate of Philip Whitcome. Dr Whitcome received his Ph.D. in 1974 from the Molecular Biology Interdepartmental Ph.D. Program and went on to a stellar career in the biotechnology industry. His gift allowed the establishment of the Whitcome Fellowship Program designed to attract highly talented students to a unique graduate training environment that emphasizes rapid progress toward groundbreaking scientific discoveries.

3D atomic details of next-generation alloys revealed for first time

Alloys, which are materials such as steel that are made by combining two or more metallic elements, are among the underpinnings of contemporary life. They are essential for buildings, transportation, appliances and tools — including, very likely, the device you are using to read this story. In applying alloys, engineers have faced an age-old trade-off common in most materials: Alloys that are hard tend to be brittle and break under strain, while those that are flexible under strain tend to dent easily.

Possibilities for sidestepping that trade-off arose about 20 years ago, when researchers first developed medium- and high-entropy alloys, stable materials that combine hardness and flexibility in a way in which conventional alloys do not. (The “entropy” in the name indicates how disorderly the mixture of the elements in the alloys is.)
