I am actively developing compact remote Raman systems for detecting minerals and chemicals in daylight for terrestrial applications and applications suitable for NASA's planetary landers and rovers.
I have served as co-I on several projects involving Raman, LIBS, and fluorescence spectroscopies. I build portable remote Raman systems capable of detecting minerals and chemicals up to 122 m away with 1 to 10 second integration times in well-lit conditions under NASA and ONR projects. I developed combined remote Raman and LIBS systems to detect minerals, explosive residues, and other hazardous chemicals from standoff distances, and I have a patent with the US patent office for combining these two technologies. Currently, I am developing compact combined standoff Raman and fluorescence systems.
I also have expertise in the field of micro-Raman spectroscopy, developing a novel approach for improving detection limits of micro-Raman systems. Apart from geological applications, I am doing research that uses Raman spectroscopy to detect bio-agents and cancer cells in collaboration with the medical community. This research has been showing breakthrough results in distinguishing cancer cells from normal cells using Raman spectroscopy.
I have a wide range of experience in various fields of physics and material science including high Tc superconductors, thin film technology, thin film sensors, hydrogen technology, electrochemistry, corrosion science, single crystal growth, high vacuum systems, x-ray diffraction, electronic noise, low temperature physics, etc.
