ENVIRONMENTALLY-RELATED PROJECTS WORKING ON

Hg CEM; LA-ICP-MS

EDUCATION

B.S. 1985, Chemistry, Loyola University of Chicago
Ph.D. 1991, Chemistry, University of Tennessee

EXPERIENCE

October 1993 - Present, Associate Chemist, Ames Laboratory/Iowa State University.
Current research: Recently started projects that involve the construction of a high resolution echelle spectrometer for continuous emission monitoring of Hg and the use of LA-ICP-MS to interrogate metals for forensic studies. Developing NIR-CCD imaging analyzer to perform nondestructive single seed analysis. Development and implementation of transient infrared spectroscopy (TIRS) for on-line monitoring of coating cure during production of fiber optic cable assemblies.
Knowledge of molecular spectroscopic techniques (IR, NIR, UV-Vis and photoacoustic) for analysis of various industrial type samples. Studies include: polymer characterization; profiling of gradients in films; sample degradation; compositional analysis of wood, glass, sludge, agricultural grains, paper and paper products, and forensic type samples (e.g., fibers and inks).
Experience with experimental instrumentation design, development and construction; programing for instrument/hardware interfacing; strong background in multivariate analysis; strong computer skills.
Development and implementation of TIRS for monitoring cure of insulation foam board on production line; determinining the chemical composition of wood chips on-line; monitoring the loading of low level nuclear waste in a microencapsulated polymer stream. Development and implementation of on-line monitors for the vitrification of high level waste based on NIR thermal emission spectroscopy .
 
April 1991 - September 1993, Postdoctoral Fellowship, Ames Laboratory/Iowa State University.
Development of infrared spectrophometric instrumentation for the characterization and monitoring of VOCs in environmental samples. Development of a mobile laboratory to conduct laser-ablation inductively coupled plasma atomic emission spectroscopy (ICP-AES) studies for the characterization of hazardous waste sites. Research also involved the design and construction of an interface between capillary electrophoresis and a reflectron time-of-flight (TOF) mass spectrometer.
 
June 1986 - March 1991, Graduate Research Assistant, Chemistry Department, University of Tennessee. Performed dissertation research at the Oak Ridge National Laboratory. Research dealt with photoelectron spectroscopy studies of atoms and polyatomics employing non-linear spectroscopic techniques, i.e., multiphoton ionization, harmonic generation, etc. Non-linear optical processes in alkalies were also studied.
September 1985 - June 1986, Graduate Research Assistant, Chemistry Department, University of Tennessee. Instructed general chemistry laboratory and recitation sections.
May 1985 - September 1985, Summer Intern, E. I. du Pont de Nemours & Company. Involved with the development of a high-performance viscometer for high molecular weight polymers.
 
September 1983 - May 1985, Teaching/Laboratory Research Assistant, Chemistry Department, Loyola University of Chicago. Instructed analytical and general chemistry laboratories. Research dealt with analytical method development employing polarography and absorption spectroscopy.
