Sunday, Nov. 14; 8:30am – 5:00pm
Dr. Perry G. Wang, LC-MS Technical Expert, Burtonsville, MD
Validation of analytical methods for the quantitative analysis of drugs, metabolites and biomarkers in a certain biological matrix is crucial for the successful conduct of nonclinical, biopharmaceutics, and clinical pharmacology studies. This short course will focus on the bioanalytical method validation using LC-MS. This course offers practical training for the practical scientists. It will take the participants step-by-step through the concepts and techniques to validate bioanalytical methods. The emphasis is on practical issues associated with the bioanalytical method validation. The participants will learn the essence of the method validation. After this course, the participants will be able to independently validate their own bioanalytical methods. How to apply the validated methods for routine assay and some typical case studies will be presented as well.
WHO SHOULD ATTEND
This short course will benefit the analytical chemists, lab supervisors, QA/QC managers, regulators, GLP auditors and CRO consultants who work in the GLP-regulated labs and the pharmaceutical industry. This course will also benefit all levels of management as a refresher course to stay current with the GLP regulations.

ABOUT THE INSTRUCTOR
Dr. Perry G. Wang worked in the pharmaceutical and medical-device industry from 2000 to 2008. He received his Ph.D. degree at Oregon State University. Dr. Wang currently works at FDA as a chemist. In addition to over twenty peer-reviewed publications, he has edited and coedited five books: “High-Throughput Analysis in the Pharmaceutical Industry”, “Monolithic Chromatography and Its Modern Applications”, “Hydrophilic Interaction Liquid Chromatography (HILIC) and Advanced Applications”, “Counterfeit Medicines”, and “High-Throughput Analysis for Food Safety”. His expertise focuses on high throughput analysis and validation by LC-MS. He prepares and teaches this course in his own capacity but not as an employee of the FDA. He has been invited to teach this course at ASMS since 2015.
