Dr. Randy Purves

Biography

Randy Purves is an Adjunct Professor and Research Scientist at the Canadian Food Inspection Agency. His work primarily focuses on bioanalytical mass spectrometry and metabolomics, with a special emphasis on developing small molecule quantification methods using liquid chromatography-mass spectrometry (LC-MS). He is actively involved in advancing high-field asymmetric waveform ion mobility spectrometry (FAIMS) for improving quantification methods, collaborating with Thermo Fisher to enhance the utility of FAIMS in small molecule research. His research includes creating diagnostic methods for detecting veterinary drug residues and utilizing untargeted metabolomic workflows to identify suitable analytes. Collaborations at the University of Saskatchewan, particularly with the Plant Sciences department, have contributed valuable insights for breeding pulse crop improvements and analyzing metabolic differences between healthy and diseased states. Additionally, Purves aims to modernize diagnostic analytical methods for the CFIA, moving away from older technologies to implement more effective approaches in metabolomics and analytical chemistry.
