Christina Macie Ryder is a postdoctoral researcher at the Center for the Study of the First Americans in the Department of Anthropology at Texas A&M University. Her work develops and refines non-destructive screening methods to optimize sampling for radiocarbon, stable isotope, and paleoproteomic analyses, with applications to Late Pleistocene megafaunal and archaeological assemblages across North America, Eurasia, and Africa. She earned her Ph.D. in Biological Anthropology from the University of Colorado Boulder, where her dissertation, Saving Old Bones, established NIR spectroscopy as a predictive tool for evaluating collagen preservation in archaeological bone. At the Center for the Study of the First Americans, she leads NIR prescreening and radiocarbon sampling within a large-scale radiocarbon dating project investigating the timing of Late Pleistocene megafaunal extinctions.
Yang Liu is a Scientific Liaison for General Chapters at the United States Pharmacopeia (USP). Dr. Liu graduated from the College of Pharmacy at the University of Illinois Chicago. He previously served as the Manager of Product Quality and Analytical Methods in the Digital and Innovation division at USP. During his tenure in the Digital and Innovation division, Liu was dedicated to evaluating emerging technologies and incorporating them into USP operations. He also led the development of digital products, including software and database creation. His focus was on advancing digital fluency and the application of digital technologies and solutions throughout the organization and for USP stakeholders. Currently, Liu is responsible for USP General Chapters development, including the spectroscopy technologies (such as UV, NIR, Raman, and NMR), process analytical technologies, and digital reference standard.
Karl Booksh is a professor in the Department of Chemistry and Biochemistry at the University of Delaware. His research interest is the development of in-situ chemical sensors for environmental, biomedical, and industrial process monitoring.
Rafael Davalos is a Margaret P. and John H. Weitnauer Jr. Chaired Professor at Georgia Tech.
Deanna Luneau is a Ph.D. candidate in environmental health sciences in the Parsons Laboratory at the State University of New York at Albany and New York State Department of Health (NYS DOH). She received her B.S. in chemistry at Rensselaer Polytechnic Institute in 2021. Her research interests include trace element analysis and their impact on human health.
Alexis Hobl is with CEA-Leti. He graduated from the École Normale Supérieure de Rennes in Electrical Engineering and from Grenoble INP Phelma with a specialization in photonics and semiconductor devices. He began his PhD in October 2024 at CEA-Leti, Université Grenoble Alpes. His research focuses on the heterogeneous integration of quantum cascade lasers (QCLs) onto silicon-based mid-infrared photonic platforms for spectroscopic applications. He develops novel hybrid III-V/Si QCL architectures and CMOS-compatible solutions enabling efficient optical coupling between III-V active regions and silicon waveguides. His work aims to advance scalable, low-cost photonic devices and circuits for applications in chemical sensing, environmental monitoring, and integrated spectroscopy.
