Lucien Weiss is an Assistant Professor of Engineering Physics at Polytechnique Montreal and head of the Biomachines Nanoscopy Lab. He performed his graduate studies at Stanford University in the lab of W. E. Moerner, where he characterized the movements of individual proteins associated with a cancer-related signaling pathway. His postdoctoral research was done in Yoav Shechtman's Nano-bio-optics lab at the Israel Institute of Technology supported by a Zuckerman STEM Fellowship. His group is developing new classes of instruments to piece together the behavior and function of biological samples over an extremely broad range of spatiotemporal scales: from single molecules to populations of cells and microseconds to days. These tools will be deployed for rapid and ultrasensitive diagnostic tools with applications including cancer detection, pathogen sensing, and personalized medicine.
