David J. Nesbitt and Nesbitt Labs : University of Colorado at Boulder

Fellow of JILA : Physicist, National Institute of Standards and Technology (NIST) : Full Professor, Department of Chemistry and Biochemistry : Lecturer, Department of Physics

Professor Nesbitt is interested in laser spectroscopy, dynamics, and kinetics of fundamental molecular, bio-molecular, and nanoparticle systems, studied at either the quantum state-to-state or single molecule level. Areas of research interest are:

  • high resolution IR laser spectroscopy of jet cooled radicals/molecular ions
  • state-to-state reactive scattering in crossed molecular beams
  • non-adiabatic dynamics and potential surface development
  • reactive/inelastic scattering at gas-liquid interfaces
  • reaction stereodynamics with aligned reagents: clusters and crossed beams
  • single molecule microscopy/kinetics of quantum dots and SERS active nanoparticles
  • time-resolved FRET studies of single RNA binding/folding kinetics
  • single molecule electrophoresis
  • photoionization imaging microscopy
  • apertureless near fieldscanning optical microscopy (ANSOM)


The group's work involves extensive use of state-of-the art cw and ultrafast pulsed laser technology, nonlinear generation of tunable mid and near-infrared laser light, fast analog electronics, scan probe methods, confocal microscopy, servo-loop control, shaped supersonic expansions, plasma discharges, kinetic analysis and quantum theoretical calculations. A central unifying goal of the research program is the elucidation of fundamental kinetics and dynamics of elementary chemical/biophysical processes from both experimental and theoretical perspectives.

Information and Application Forms
Postdoctoral applicants who are U.S. citizens can also apply for competitively awarded National Research Council Fellowships (roughly $55K/year) to work in the Nesbitt group through the National Institute of Standards and Technology. Application materials and information can be obtained either via the NIST/NRC website or by contacting Dr. Claire M. Saundry, (301) 975-2386. Applications and proposals are typically due at the end of January for postdoctoral studies commencing no later than January 1 of the following year.

Dr. Nesbitt is an Alexander von Humboldt Fellow and therefore postdoctoral applicants who are German or Swiss citizens can also apply to the Humboldt Foundation for financial support to work in the Nesbitt labs.
