We invent novel optical probes–luminescent nanocrystals and organic fluorophores–as biosensors and single-molecule probes, develop bioconjugation and targeting chemistries, and image live cells  with these reagents.  We aim to use interesting and unusual new luminescent nanomaterials to address  fundamental questions of cell function. 

We’re hiring!   We’re especially interested in new (or soon-to-be) PhDs with experience in fluorescence, chemical biology, or organic synthesis.  

Check out our recent Nature paper on infinite photoswitching of avalanching nanoparticles and imaging with sub-Angstrom precision.

We’re based at the Molecular Foundry at Berkeley Lab.  See our amazing view of Berkeley and San Francisco live here.
