Profile Summary

Fulfilled many projects on optical diagnostics (plasma emission, LIBS, Raman, laser-induced fluorescence, diode laser absorption). I am a laser spectroscopist and plasma physicist with a 30-year experience in these fields. I have extensive management experience in government contacts with NASA, DOE and DoD, particularly in product development of an advanced LIBS spectrometer which used the improved chemometrics algorithms for the analysis of spectroscopic data. I used laser ablation plasmas for chemical analysis of structured electronic and optical materials, including Li-ion batteries and photovoltaics. I conducted instrumentation and methodology development for the remote laser-induced breakdown and Raman spectroscopic identification of a multitude of diverse material. I have made improvements in the measurements of atmospheric aerosols using optical cavity ring-down instrumentation and fulfilled a project on optical diagnostics (emission- and diode laser-based absorption) of inductively coupled plasma (ICP) aimed on applications in nano- and micro-electronics fabrication and also on diode-laser sensors for planetary exploration. My projects included work on optical diagnostics of enclosed ICP designed for trace analysis of reactive specialty gases, where I elucidated novel effects in a halogen-gas ICP and significantly improved its detection capability. I designed and tested an interface between analytical ICP-mass spectrometer and gas chromatography (GC-ICP-MS) and has managed projects on development of laser-induced gas breakdown spectroscopic (LIBS) and gas-chromatographic analyzers for high-purity gases used in the semiconductor industry. I was the Applied Spectra’s lead on successful implementation of a multi-sensor data fusion project. My software and database experience also includes the development and administration of the concept, acquisition and classification of information for a major database on laser-based techniques and technologies. I have served as a manuscript/proposal reviewer and authored more than 120 publications and presentations, including 3 book chapters and several patents on analytical methods. Supervised MS and PhD students. Instructed microwave sample preparation courses.
