Christophe Lachance-Brais



My name is Christophe Lachance-Brais and I love molecules! I get to play with them all day working on DNA hydrogels and small-molecule/DNA supramolecular assemblies. I come from right here, Montréal, a beautiful city of festivals and potholes. I like to ski, climb, and canoe in this beautiful country. Proud owner of a lizard, a snake and a slime mold!

Sean Laxton


Growing up in Vancouver, British Columbia, and now living in Montréal, I can unequivocally say that I am fortunate to have lived in two of the most beautiful cities in the world! I received my BSc from SFU, where I discovered my passion for materials chemistry and nanoscience. As a graduate student, my research involves printing DNA onto nanoparticles to generate highly specific and programmable assemblies. Living in Montréal has motivated me to improve my hockey skills, eat more poutine, and wait in line for quality bagels. I feel more Canadian than ever!
