Marc-André Legault

Dr. Marc-André Legault is an Assistant Professor in the Faculty of Pharmacy at Université de Montréal and researcher at CHU Sainte-Justine. His work integrates bioinformatics, genetic epidemiology, and machine learning to predict drug responses and advance personalized medicine.

Using multi-omics data from biobanks (e.g., UK Biobank), he models drug effects through genetic proxies and develops AI tools for drug repositioning. Current projects include predicting pediatric drug efficacy and validating therapeutic targets via Mendelian randomization. He teaches bioinformatics methods including Mendelian randomization techniques.
