Alex Scheeline is a distinguished analytical chemist and Professor Emeritus in the Department of Chemistry, School of Chemical Sciences at the University of Illinois at Urbana-Champaign. He earned his BS in chemistry from Michigan State University in 1974 and his PhD in chemistry from the University of Wisconsin–Madison in 1978, where he focused on analytical and physical chemistry. Shortly after his doctoral work, he completed a National Research Council postdoctoral fellowship at the National Bureau of Standards before beginning his academic career. He served as an assistant professor at the University of Iowa from 1979 to 1981, after which he joined the University of Illinois faculty, where he remained for several decades
Ian Ciesniewski is a Technical Director with Mettler-Toledo, in Columbus, Ohio. His work manages the Mass Metrology business in the USA, developing and delivering strategies for the scientific measurement market, including regulatory compliance for pharmaceutical, biotechnology and related industries.
Martin Resano is a Coordinator of the Rapid Analysis Methods with Spectroscopic Techniques (MARTE) group and as part of the Aragon Institute for Engineering Research (I3A) at the University of Zaragoza. His research group works with inductively coupled plasma–mass spectrometry (ICP-MS) and laser-assisted techniques to develop minimally invasive approaches for clinical analysis.
Sarah Theiner is a Sales Manager at Nu Instruments based out of Bozeman, Montana. Theiner’s research integrates laser ablation inductively coupled plasma–mass spectrometry (LA-ICP-MS), single-cell ICP-MS, and quantitative calibration strategies to address biological and clinical questions. Her research is designed to advance atomic spectroscopy as an effective platform for elemental and imaging-based studies. Theiner is most known for developing high-resolution imaging workflows using LA-ICP-time-of-flight mass spectroscopy (TOFMS) and multi-element analysis techniques for biological and clinical applications. She was Spectroscopy’s 2026 Emerging Leader in Atomic Spectroscopy awardee.
James Cizdziel is a Professor and Chair of the Department of Chemistry and Biochemistry at the University of Mississippi. Cizdziel earned his BS from the State University of New York at Buffalo in 1991 and his PhD from the University of Nevada, Reno in 1998, with research interests spanning analytical, environmental, and forensic chemistry. His research group has developed new methods for studying microplastics, trace elements, mercury biogeochemistry, atmospheric sampling using UAVs, and forensic analysis of trace evidence, including from three-dimensional (3D)-printed firearms, and he has published more than 90 papers with funding from the Environmental Protection Agency (EPA), the Department of Education (DOE), the National Science Foundation (NSF), and the Department of Justice (DOJ).
Lucy Semerjian is a Chair and Associate Professor in the Department of Environmental Health Science at the University of Sharjah in Sharjah, United Arab Emirates.
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.
