Judy Stone, MT (ASCP), PhD, DABCC has worked with LC-MS in diagnostic laboratories since 1999. Her clinical practice involved small molecule method development, instrument to instrument and instrument to LIS interfacing, LC-MS automation, monitoring quality of LC-MS methods in production and staff training for clinical LC-MSMS. She served as faculty chair for the 2009 AACC online certificate program “Using Mass Spectrometry in the Clinical Laboratory”, as a scientific committee member for the MSACL Practical Training track, and was editor-in-chief for the AACC Clinical Laboratory News quarterly feature series on Clinical LC-MS. She enjoys documenting and presenting esoteric as well as absurdly common LC-MS problems in creative ways in order to help trainees learn troubleshooting (and avoid repeating her mistakes).

Jacqueline Hubbard received her BS degree in Biochemistry from the University of Vermont. She then earned her MS and PhD in Biochemistry and Molecular Biology from the University of California, Riverside (UCR). Following a one year postdoc at UCR, Dr. Hubbard completed a Fellowship in Clinical Chemistry at the University of California, San Diego Health. She is board certified in Clinical Chemistry by the American Board of Clinical Chemistry. In 2019, she took a position as an Assistant Professor in the Department of Pathology and Laboratory Medicine at the Geisel School of Medicine at Dartmouth and as the Assistant Director of Clinical Chemistry at Dartmouth-Hitchcock Medical Center. There, she focused on developing and validating drugs of abuse assays and SARS-CoV-2 serology testing. After serving as a Lab Director for a small reference laboratory, she joined Beth Israel Deaconess Medical Center as the Co-Director of Clinical Chemistry and Director of Toxicology in 2024. She is also an Assistant Professor of Pathology for Harvard Medical School. Her research focus still includes mass spectrometry method development and toxicology test interpretation.

Dr. Michael Vogeser, MD, is specialist in Laboratory Medicine and senior physician at the Hospital of the University of the Ludwig-Maximilians-University Munich, Germany (LMU; Institute of Laboratory Medicine). As an Associate Professor he is teaching Clinical Chemistry and Laboratory Medicine. The main scope of his scientific work is the application of mass spectrometric technologies in routine clinical laboratory testing as translational diagnostics. Besides method development in therapeutic drug monitoring and endocrinology a further particular field of his work is quality and risk management in mass spectrometry and in clinical testing in general. Michael has published >240 articles in peer reviewed medical journals. Michael heads the Commission for In Vitro Diagnostics in the German Association of Scientific Medical Societies (AWMF).)

Dr. Budelier the Medical Director of Clinical Chemistry and Toxicology at TriCore Reference Laboratories and Clinical Assistant Professor of Pathology at the University of New Mexico. Her research interests are broadly focused on developing clinically useful, mass spectrometry-based assays to improve diagnosis and treatment of human disease. Her expertise are in Toxicology/TDM, assay development and validation, and protein quantification.

Alejandro Molinelli, PhD is Director of the Clinical Pharmacokinetics Laboratory in the Department of Pharmacy and Pharmaceutical Sciences at St. Jude Children's Research Hospital. His duties include clinical consultancy, technical and regulatory oversight of the laboratory, and method development and validation. Dr. Molinelli also serves as a Clinical Chemist Consultant with the Department of Pathology at St. Jude. Prior to joining St. Jude Dr. Molinelli completed a Clinical Chemistry Fellowship at the University of Washington in Seattle; obtained his PhD in toxicology at the University of North Carolina at Chapel Hill; and bachelor’s and master’s degrees in biology and biochemistry at the University of Puerto Rico. Dr. Molinelli’s professional interests include therapeutic drug monitoring, clinical toxicology, and quality improvement.

Dan Wang, PhD, DABCC (CC, TC), serves as a medical director of Clinical Chemistry at Akron Children’s Hospital, in Akron, OH, and holds an assistant professor position at Northeast Ohio Medical University in Ohio. Dr. Wang is board-certified in both Clinical Chemistry and Toxicological Chemistry by the American Board of Clinical Chemistry. She earned her PhD degree in Clinical-Bioanalytical Chemistry from Cleveland State University and completed Clinical Chemistry fellowship at the Medical University of South Carolina.

Dr. Wang is actively involved with professional organizations, including ASCP, the Association for Diagnostics & Laboratory Medicine, and the Society for Inherited Metabolic Disorders. Her passion lies in pediatric laboratory medicine, with a specific focus on general chemistry, toxicology, and inborn errors of metabolism. Dr. Wang is actively engaged in research with innovative approach aimed to bridge the gap between the diagnostic needs and the availability of Food and Drug Administration approved tests for pediatric patients.
