Description
Our group’s primary research focus is on the development of advanced in-situ spectrometers for planetary science. Currently we have several on-going projects to develop novel Raman spectrometers, Laser Inducted Breakdown (LIBS) spectrometers, laser delivery systems, collection optics and probeheads.
We are seeking Postdoctoral Scholars interested in participating in the development of an integrated Raman/LIBS spectrometer that can measure spectra at standoff distances ranging from several centimeters to several meters. The goal of this project is to demonstrate that LIBS/Raman spectra can be used to perform quantitative mineralogy and elemental analysis in extreme environments. One goal is to demonstrate quantitative mineralogy/elemental analysis of rocks samples held in a simulated Venus surface environment of 465?C and 93 bar. Another goal is to demonstrate that this technique is viable in very cold, high-pressure liquid environments that may be present beneath ice-covered oceans of Europa or Enceladus.
Postdoctoral scholars are also sought to assist in the development of specialized ultraviolet Raman spectrometers designed to detect the resonant enhanced Raman spectra of conjugated or aromatic organic compounds representing signatures of life within Mars, Europa, Enceledus, Titan or other bodies in the solar system where life may exist. The successful candidate will be involved in the development of a multi-wavelength UV source as well as a UV Echelle Raman spectrometer enabling resonant Raman spectra of samples illuminated with multiple UV wavelengths to be processed simultaneously. Alternatively, Postdoctoral scholars may wish to explore the development of specialized probeheads utilizing metalized or liquid core optical waveguides to enhance sensitivity or utility of Raman, fluorescence, LIBS, or atomic absorption in-situ instruments.
All of the projects above are quite lab oriented. Candidates must have a strong interest in hands-on laboratory-based instrument development work. Candidates with expertise in lasers, optical instrument design, electronics, atomic emission spectroscopy, molecular spectroscopy, and chemometric techniques (PLS, nonlinear PLS, PLS-SVC, Kernel based methods, etc) are encouraged to apply.
