Bio

Dave Chandler was born in Albuquerque New Mexico.  He received his BS degree in Chemistry from the University of New Mexico in 1975 and his PhD in Chemistry in 1979 from Indiana University where he worked under Dr. George Ewing studying vibrational energy transfer in cryogenic liquids.  Following graduate school he accepted a postdoctoral fellowship in the laboratory of Dr. Richard N. Zare at Stanford University where he studied unimolecular reactions after excitation of a high vibrational overtone transition.   He joined the Combustion Research Facility at Sandia National Laboratory in 1982 and was promoted to Senior Scientist in 2000.

Research Interests

Dr. Chandler’s research interest have centered around the utilization of multiplex detection techniques, like Ion Imaging, for the study of chemical dynamics both unimolecular photodissociation and bimolecular collision dynamics.  He has performed extensive measurements of differential cross sections, alignment and orientation of products of photodissociation products and inelastic collisions between molecules and atoms under single collision conditions. Most recently he has utilized crossed molecular beam scattering to cool molecules by collisions to temperatures in the milliKelvin range.  Other research interests include Cavity Ring-Down spectroscopy and the development of a new dual etalon cavity technique for high-resolution, high-sensitivity spectroscopy.  In collaboration with Dr. Kevin Strecker (Sandia) I  have developed and patented a new type of Fourier transform spectrometer that relies upon the interferogram generated by the output of two confocal etalons.  This new spectrometer will provide spectral resolution of tens of kilohertz from the infrared to the ultra violet.  Additionally, this spectrometer can perform time resolved spectra a thousand times faster than existing techniques.
