Dr. Romy Hanna is a Research Scientist at the University of Texas High-Resolution X-ray CT Facility (UTCT) in Austin. Her research on primitive carbonaceous chondrite meteorites and asteroids aims to build a more complete picture of the formation conditions of this material in the early solar nebula, how it accreted from the chondrite parent bodies, and how it has been modified by secondary processes on these asteroids. She uses a variety of analytical techniques to address these questions including electron microbeam [including electron backscatter diffraction (EBSD)], X-ray computed tomography (XCT), and visible to near infrared (VISNIR) and thermal infrared (TIR) spectroscopy, often combining these techniques in novel ways. Recent projects include using pressurize noble gas with XCT to examine porosity and EBSD to map micron-sized grain alignment in fine-grained chondrites. She is a Participating Scientist on NASA’s OSIRIS-REx mission, on the sample return mission to near-Earth carbonaceous asteroid Bennu, and the PI of the NASA Planetary Science Enabling Facility grant to UTCT, which partially supports NASA PSD-funded researchers to use XCT for their research. She is also working to bring miniaturized XCT into space with a variety of landed mission concepts and instrument development efforts.

Ge Wang is the Clark-Crossan Chair Professor and Director of the Biomedical Imaging Center, RPI, USA. He focuses on AI-based medical imaging. He published the first spiral cone-beam CT method in the early 1990s. There are ~200 million CT scans yearly, with a majority in the spiral cone-beam mode. He published the first perspective on deep imaging in 2016 and many follow-up papers. He is Fellow of IEEE, SPIE, AAPM, OSA, AIMBE, AAAS, and NAI, and recognized with various awards such as IEEE R1 Outstanding Teaching Award, EMBS Career Achievement Award, SPIE Meinel Technology Award, and Sigma Xi Chubb Award for Innovation.

Paul is an international expert in biomechanics, comparative and translational neuroscience, and contrast-enhanced computed tomography imaging. He is an associate professor and Director of Global Graduate Programs at the University of Arizona College of Medicine, Tucson, and a research associate at the American Museum of Natural History in New York City. His methods development focuses on establishing cell-to-skull, 3D-imaging pipelines by integrating standard and novel anatomical visualization techniques. Paul's efforts are organized around collaboration and community building. He helped to launch diffusible iodine-based contrast-enhanced computed tomography (diceCT) for 3D soft-tissue imaging; he co-founded the MicroCT Imaging Consortium for Research and Outreach (MICRO) to serve the imaging needs of the U.S. Interior Highlands; and he co-organizes the global Non-Clinical Tomography Users Research Network (NoCTURN) to address FAIR and Open Science issues in the field. As a result, Paul has run dozens of workshops and lectured internationally about CT methodologies and applications, ensuring that CT users have resources and opportunities to address the educational needs and scientific questions most important to them.

Dr. Amanda Krause is an Assistant Professor in the Materials Science and Engineering Department at Carnegie Mellon University. Her research focus is engineering interfaces and microstructures for improving the mechanical performance and degradation response of ceramics used in extreme environments. She specializes in 3D characterization of microstructures using X-ray diffraction microscopy and electron backscattered diffraction. She uses these methods to challenge conventional theories of sintering and grain growth. Her research goal is to develop machine learning techniques for these sparse, but rich multi-dimensional datasets to elucidate fundamental grain growth phenomena. She is a recipient of the NSF CAREER award (2022).
