WORK EXPERIENCE:
Sept. 1999-Present:
, Zeller Research Ltd.
Performing a wide range of tasks, focusing on computer and circuit
board manufacture. Wrote Standard Operating Procedures for a variety of
surface mount and soldering machines. Programming, maintaining and operating
machinery for fine pitch surface mount contract electronics manufacture.
Sheet metal fabrication and CNC machining of aluminum and composite materials.
Program management, purchasing, manufacturing and design for production of
computer video systems for roadside traffic monitoring. Have written a 100+
page illustrated assembly manual for manufacture of a thermoelectrically
cooled computers for harsh environments. Generated and maintained a complete
bill of materials for continuos production of roadside station computers.
Jan. 1999-May 1999:
Visiting Assistant Professor of Physics
, Miami University
Taught "Physics and Society" to 130 freshman non-majors.
Sept. 1996-Aug. 1997:
Visiting Assistant Professor of Physics
, Whitman College
Taught Classical and Quantum Mechanics, Maintained and taught Intro.
Lab, and conducted research with undergraduate student assistance on crystal
growth and fluid dynamics through flow visualization and time-lapse computer
video capture.
July 1994-Aug. 1996:
Visiting Assistant Professor of Physics
, Kenyon College
Responsibilities included teaching Modern Physics, Thermal Physics,
and E&M to undergraduates, as well as laboratory and thesis/independent study
research supervision and academic advising. Research projects included refurbishment
and operation of a pulsed Nitrogen laser and flow visualization
studies in Rochelle Salt crystal growth. Worked on developing and maintaining
departmental laboratories and computer systems.
Nov. 1992-Nov. 1993:
Joint Study Research Contractor
, IBM T.J. Watson Research Center
Conducted Ph.D. research. Thesis title: "Enhancement of the Electron
g-factor in Silicon-Germanium Heterostructures". Thesis directors: Phillip
Stiles and Frank Fang. Worked on epitaxy of SiGe on Si and Ge substrates by
Molecular Beam Epitaxy and High Vacuum Chemical Vapor Deposition. Fabricated
devices for and did measurements of low-temperature magneto-transport (Quantum
Hall Effects), including work at the National High Magnetic Field Laboratory
at MIT.
Jan. 1990-Aug. 1993:
, Brown University Physics Department.
Varied work in semiconductor Liquid Phase Epitaxy, material
characterization, surface passivation, Microelectronic device design and fabrication,
low temperature surface transport in semiconductors, and sputtering of group
III nitrides for electroluminescent applications. Successfully demonstrated
a GaN Blue electroluminescent diode, designed and manufactured by sputtering
and shadow-masking processes. Built and maintained vacuum systems, photoluminescence
and Hall Effect apparatus, as well as designing and assembling a
15T superconducting magnet system with a He3 refrigerator. Worked extensively
with characterization techniques including ellipsometry, photoluminescence,
SIMS/AES/ESCA, capacitance-voltage profiling and resistivity measurements.
Assisted in the writing of two proposals to NSF and other agencies:
"Investigation of Quantized Surface Space Charge Layers" (May, 1992), and
"Growth and Characterization of Single Crystals of Group III Nitrides" (Sept.,
1992.).
Aug. 1988-Nov. 1989:
Process Development Engineer
, Spire Corporation, Bedford, MA
Responsibilities included re-design and rebuilding of Spire's large
scale Metal-Organic Chemical Vapor Deposition reactor, and testing machinery
and developing processes for its operation. Problems solved included
elimination of RF interference through extensive shielding and the use of
optical fiber pyrometry instead of thermocouples, and a five-fold reduction
in power consumption through infra-red reflecting insulation. Conducted
extensive experiments in flow visualization, and verified results through
statistical design of crystal growth experiments and modification of flow
systems. Gained extensive experience in handling and disposing of highly
toxic materials. Worked in Quality Control, doing measurements including
photoluminescence, sectioning and staining epitaxial structures for thickness
measurements, reflectivity measurements and capacitance depth profiling for
impurity concentration measurement. Designed and constructed a low
temperature photoluminescence and Hall effect measurement system. One
proposal written to NSF: "Cryogenic Waste Gas Scrubber/Power Cogenerator",
funded for $50,000 in Dec. 1990.
Jan. 1987-Aug. 1988:
, Brown University Physics Department.
Worked on Liquid Phase Epitaxy of gallium arsenide and
characterization of epilayers, preparation and testing of germanium MOS Field
Effect transistors, sputtering of gallium nitride and various other
semiconductor projects. The Ge work was based on a high pressure (~5000 Atm.)
oxidation of Ge surfaces. Gained extensive experience in photolithography
and semiconductor clean room techniques. Did some consulting work in
measurements of thermal emissivity of materials for paper drying. Also
supervised a lab of three graduate and three undergraduate research assistants.
Oct. 1985-Jan. 1987:
, Brown University Physics Department.
Worked on Liquid Phase Epitaxy of gallium arsenide, thin film
processing and general lab maintenance. Senior thesis titled "Growth of a
Zone Leveled Single Crystal of GaInAs", Dec., 1986. The Thesis project
involved furnace modification and profiling, technical glassblowing of quartz
crucibles, and X-ray diffraction and photoluminescence profiling of boules.
Jan. 1985-July 1985:
, S.C. Plumbing, Lahaina, HI.
