Sam Peng

Sam Peng is an Assistant Professor in the Department of Chemistry at the Massachusetts Institute of Technology. His research focuses on developing optical imaging techniques and nanoprobes to enable long-term single-molecule imaging in living systems. The Peng Laboratory investigates molecular interactions responsible for human diseases, integrating tools such as single-molecule microscopy, super-resolution microscopy, spectroscopy, and nanomaterial engineering. His work explores molecular dynamics, protein-protein interactions, and cellular heterogeneity in neurobiology and cancer biology.
