Dr. George Katselis

Dr. George Katselis is an Assistant Professor in the Division of the Canadian Centre for Health and Safety in Agriculture (CCHSA) in the Department of Medicine, College of Medicine at the University of Saskatchewan.  George moved from his hometown Thebes in Greece to Halifax, Nova Scotia, Canada to study Instrumental Chemical Analysis/Analytical Chemistry at Dalhousie University earning a B.Sc. with Honours (supervisor: Dr. Louis Ramaley).  After a brief stay back in Greece, he returned to Canada to pursue graduate studies at the University of Saskatchewan where he earned a M.Sc. in Analytical Chemistry of Natural Products (supervisor: Dr. Branka Barl) and a Ph.D. in Pharmaceutical Sciences / Analytical Chemistry (supervisors: Dr. Dennis Gorecki & Dr. Branka Barl).  It was during his Ph.D. studies that George discovered his true passion in Mass Spectrometry.  In 2005, he moved to Los Angeles, California, USA and the City of Hope Medical Center to do his Post-Doctoral Fellowship in Mass Spectrometry (MS)-based Proteomics under the mentorship of Dr. Terry Lee, a modern era mass spectrometry pioneer.  In 2010, he returned to the University of Saskatchewan to manage the Mass Spectrometry lab and in 2012 he joined the Department of Medicine and CCHSA in his current capacity.  In 2014, he established, and currently leads, the CCHSA Mass Spectrometry lab which is part of the Health Sciences Core Mass Spectrometry Facility.

Dr. Katselis’ areas of research are in Functional and Structural Proteomics and the Biomedical Aspects of Human Health and he employs Mass Spectrometry-based techniques for: Clinical Proteomics, Metabolomics, and Lipidomics; Biomarker Analysis (Discovery and Validation); Structural Characterization of Proteins (e.g. Protein-Protein Interactions, Post-translational Modifications of Proteins); Environmental, Agricultural, Rural and Occupational Health Applications; Pharmaceutical Analysis; Analytical Instrumentation Chemistry.


Dr. Randy W. Purves

Dr. Randy Purves is a professional research associate in the College of Agriculture and Bioresources at the University of Saskatchewan.  He obtained his B.Sc. Honors (with distinction) in Applied Chemistry at the University of Calgary in 1992.  His Ph.D. in Analytical Chemistry at the University of Alberta involved developing electrospray mass spectrometry under the supervision of Prof Liang Li (conferred 1997).  Dr. Purves has over 20 years of experience applying mass spectrometry to solve a diverse set of analytical challenges.  He was a leader in recognizing the importance of the complementary nature of ion mobility devices for use with mass spectrometry and co-founded Ionalytics in 2001.  He was an integral part of a team at Ionalytics that produced the first commercial ion mobility device for use with mass spectrometry (2003) and he continues his work in this area through a collaboration with Thermo Fisher.  Dr. Purves has a strong background in both metabolomics and proteomics that has involved leading small research groups at Ionalytics, Merck Frosst, and also as a manager of the mass spectrometry and proteomics facility at the National Research Council of Canada.  

Dr. Purves is an expert in applying mass spectrometry to solve complex analytical problems and has been involved in multiple collaborations across disciplines.  Currently, his primary interests involve improving nutritional value of Agricultural crops and better understanding biochemical pathways through the use of integrated omics strategies.
