OBJECTIVE:	Senior Project Engineer or Senior Staff Scientist position with
		design, development, and technical management responsibilities
		in high technology research and development.

EDUCATION:	Ph.D. - Chemical Physics, University of Rochester
		Rochester, NY (4/82)

		*Dissertation: "Laser-Radio Frequency Double Resonance
		Spectroscopy of Molecular Iodine and Deuterated Formaldehyde"

		M.S. - Physical Chemistry, University of Rochester
		Rochester, NY (5/76)

		B.S. - Chemistry, State University of New York at Albany
		Albany, NY (5/73) Magna Cum Laude 3.6/4.0 GPA; Mnr: Mathematics

EXPERIENCE:	July 1987 - Present	Senior Scientist/Project Engineer
					Space and Technology Group, TRW Inc.
					Redondo Beach, CA

		"Assistant Program Manager" for Optics Engineering on the ALPHA
		chemical laser program (1/90 - present). Managed the activities
		of the Optical Resonator Assembly (ORA), resonator Alignment
		Unit (AU) and Optical Diagnostics Assembly (ODA) subprojects.
		Directed the activities of three subproject engineers and 18
		other engineers and technicians. Designed an HF ground state
		absorption diagnostic as well as the designs of several other
		new diagnostics and diagnostic upgrades.

		"Subproject Manager" for the Optical Diagnostics Assembly (ODA)
		on the ALPHA chemical laser program (8/89 - 1/90). Did the
		project engineering for the ODA subproject for three of four
		lasing tests during the ALPHA I contract. Directed the
		activities of 12 engineers and technicias. Was personally
		responsible for the pretest alignment of the ODA and certifying
		it ready for test. ODA data was successfully acquired on all
		tests. Designed and installed three new diagnostics during this
		time as well. Was responsible for the test quick-look data
		reduction and analysis, and presentation of the results to the
		customer.

		"Chief Scientist" for the Optical Diagnostics Assembly (ODA) on
		the ALPHA chemical laser program (7/87 - 8/89). Was responsible
		for the system calibration and effectiveness. Made numerous
		design improve- ments to the ODA beam train. Wrote test plans,
		and alignment and calibration procedures. Supervised the
		execution of the test plans and calibrations, and was personally
		responsible for the installation and alignment of the ODA at the
		test site. Did the data reduction and analysis of the
		calibration tests. Also did the lasing test quick-look data
		reduction and analysis, and presentation of the results to the
		customer.

		March 1986 - July 1987		Senior Staff Scientist
						JANBEC Corporation
						San Diego, CA

		"Project Engineer" on a large, proprietary high technology
		research and development program for a confidential client.
		Designed laser subsystems to meet SOW performance minimums and
		goals over a range of operating conditions. Organized the
		projects and did bottom-up estimate-to-completion schedule and
		budget for each subsystem. Generated a staffing plan and wrote
		job descriptions. Specified lab and project equipment.

		October 1982 - March 1986	Member of the Technical Staff
						Rocketdyne Division
						Rockwell Intl Corporation
						Canoga Park, CA

		"Lead Diagnostic Engineer"  for outcoupled laser beam
		diagnostics during the TAU chemical laser program (7/83 -
		10/85). Planned, designed, and aligned the outcoupled laser
		beam diagnostics' optical system. Conducted the near field
		wavefront, near field intensity, and far field intensity
		diagnostic experiments. Was backup diagnostic engineer for the
		far field beam quality, outcoupled spectral content, and mode
		beat spectrum diagnostics. Also maintained the diagnostics'
		optical system alignment throughout the program. Directed the
		activities of three other diagnostic engineers, one electronics
		technician, and two mechanical technicians. Coordinated
		activities with cognizant project engineer and with facility
		test engineers. Wrote many diagnostics checkout, calibration,
		and test checklist procedures. Wrote several sections of the
		program final report.

		"Diagnostic Engineer"  for gain medium diagnostics during the
		SIGMA chemical laser program (10/82 - 6/83). Revised the design
		and significantly improved performance of the lasing spectral
		content and fast response flux monitor diagnostics. Conducted
		these diagnostic experiments during test and also supported the
		small signal gain and mode footprint diagnostics. Directed the
		activities of a mechanical technician during the assembly and
		installation phases of the diagnostics preparation for testing.

		April 1982 - October 1982	Post Doctoral Research Associate
						University of Rochester
						Rochester, NY

		Started project to measure both ground and excited state
		electronic properties of TiN in a flowing discharge reaction by
		laser induced fluorescence detected double resonance
		spectroscopy.

		Designed, fabricated, and assembled microwave discharge source,
		flow cell, and vacuum system. Set up pulsed dye laser and pulsed
		detection systems.

		September 1974 - April 1982	Graduate Student
						University of Rochester
						Rochester, NY

			(Thesis Advisor: Professor John S. Muenter)

		Measured electronic properties of molecules by high resolution
		laser double resonance spectroscopy. Experiments done on CO+,
		CN,ClF, and SO2. Detailed investigations carried out on I2 and
		formaldehyde.

		Designed, analyzed, and assembled cw dye laser with two
		intracavity focal points. Second focal point used to make
		tunable uv laser light by Type I second harmonic generation in
		a nonlinear optical crystal. Wrote computer code to
		systematically analyze various two focal point, cw dye laser
		resonator configurations for focal spot sizes and locations,
		resonator stability region, and completely astigmatically
		compensated cavity geometry while maintaining optimum spot size
		for second harmonic generation.

		June 1973 - September 1974 Production Synthetic Organic Chemist
					   Eastman Kodak Company
					   Synthetic Chemicals Division
					   Rochester, NY

		Sythesized and purified organic chemicals in 1 to 100 kg.
		batches. Did scale-up work for development groups.
