Brian Gilfix

Brian Gilfix, MD, PhD is an active Associate Professor in the Department of Medicine at McGill University's Faculty of Medicine and Health Sciences and serves as an Investigator at the Research Institute of the McGill University Health Centre (RI-MUHC) at the Glen site. His academic appointment is specifically within the Division of Biochemistry at the MUHC, where he contributes to both clinical and research activities focused on molecular diagnostics and metabolic disorders.

Dr. Gilfix's research program centers on developing innovative techniques for analyzing DNA mutations and measuring blood substances for disease diagnosis. His work prominently features homocysteine analysis, HPLC methodology, and molecular diagnostics approaches. His expertise spans genetic disorders, vitamin metabolism (particularly B12 and folate), methylmalonic aciduria, and laboratory testing methodologies. His research has significant clinical applications in hematology, metabolic diseases, and genetic diagnostics.

The publication record reveals consistent scholarly output with a focus on metabolic disorders and diagnostic techniques. Recent work shows expansion into neurodegenerative disease biomarkers (Alzheimer's research) while maintaining his longstanding expertise in vitamin metabolism and genetic disorders. His collaborative pattern indicates strong research partnerships, particularly with Rosenblatt DS and Watkins D, suggesting integration within specialized research networks focused on inborn errors of metabolism.

Dr. Gilfix's research has direct clinical applications in diagnostic laboratory medicine, particularly in identifying genetic mutations and metabolic abnormalities. His work bridges basic science with clinical practice, contributing to improved diagnostic approaches for complex metabolic conditions. The consistent publication record across multiple decades demonstrates sustained scholarly activity and evolving research interests within the molecular diagnostics field.
