Professor Fabien Pinaud is the Principal Investigator of the Single Molecule Biophotonics Group. The Pinaud Lab focuses on using a variety of single molecule microscopy techniques to study how nanoscale cellular compartments modulate the diffusion and the activity of proteins involved in normal and pathological cellular signaling and responses. We also develops ultra-sensitive imaging probes that quantitatively report and influence biomolecular interactions in living cells and animals. Some of these probes have potential applications for cancer diagnostics and therapeutics.
