I teach Chemistry at McGill University, and I work with undergraduate, MSc, PhD and postdoctoral students pursuing studies in Nucleic Acid Chemistry & Biology. With them, I have been developing chemically modified oligonucleotides and methods for their synthesis. Through our work, we have discovered many of them have properties that render them adaptable for numerous biological applications. In some cases, these studies have been essential in deciphering structure-function relationships between our oligomers and enzymatic machinery associated with the antisense, CRISPR-Cas9, RNAi, and RNA splicing pathways. We start with chemistry to design and construct molecules, test them biochemically/biophysically in vitro and then, through collaborative work, we apply them in live-cells and animal disease models (Duchenne Muscular Dystrophy, ALS, etc.).
