He oversees student research projects and initiates industry collaboration with university. He is recognized as a lead academician in the embedded systems/electronics focus of CSU's Applied Physics program.|
|Years: to Present||Employer: Undisclosed||Title: Director||Department: Sensor Products||Responsibilities: Expert was responsible for the overall management and technical leadership of the fiber optic sensor group, including scientists, engineers, salespeople, and technicians. This included R&D, product management, engineering, business development, sales and marketing; instrument electronic design, including photoreceivers, embedded processing and CPLD and FPGA design; initiating supplier relationships with semiconductor, medical, automotive and aerospace customers; and software and product development. He designed, built, tested, and sold instrumentation for  medical thermal therapy equipment (particularly hyper- and hypo-thermic methods) and  semiconductor metrology.|
|Years: 1996 to 1998||Employer: U.S. Naval Research Laboratory||Title: Senior Scientist||Department:||Responsibilities: Expert developed devices and applications for chalcogenide (CG) fibers and
integrated optics. He authored three patents and several publications resulting
from his research. R&D accomplishments: first chalcogenide SM fused coupler; first IR singlemode near-field optical microscope probe; first model of 1.3 um CG fiber amplifiers; made CG fiber Bragg gratings. Expert also built an electro-mechanical system for fiber tapering. Other R&D areas: IR scene
simulation, Raman amplifiers in CG, chemical sensors, microlensed fibers,
photosensitive waveguides & photo-doping.
|Years: 1992 to 1996||Employer: National Institutes of Standards and Technology||Title: Research Associate||Department:||Responsibilities: He conducted R&D in quantum optics of vertical-cavity surface-emitting semiconductor lasers. He set up, instrumented, wrote code for, and maintained optical characterization laboratory. Expert also provided primary optical characterization support for all structures grown in NIST MBE machine. He designed, modeled and characterized laser structures for MBE growth. Expert designed instrumentation and wrote instrument control software for photon counting spectroscopy system (noise floor 4 photons). Other measurements: reflectance, photoluminescence, DCXRD, SEM, and X-ray. R&D accomplishments included quantum well interdiffusion, crosstalk in
VCSEL arrays, and angular and spectral dispersion of and spectral drift of the
fundamental lasing mode in VCSELs.
|Years: 1987 to 1992||Employer: Bandgap Technology Corp||Title: Senior Materials Characterization Engineer||Department:||Responsibilities: Expert was the primary quality control officer for a start-up compound semiconductor manufacturing company. He designed and supervised the construction of a characterization laboratory with a $2M+ budget. He also developed and maintained characterization facilities (hardware, software, training, calibration, etc). Expert was responsible for the analysis and
interpretation of all wafer test data. He was one of 4 lead engineers responsible for the design and equipping of 2000 sq-ft Class 10 clean room. Techniques used: PL, photoreflectance, parametric testing, C-V profiling, Hall effect, resistivity/particulate screening, Nomarski microscopy, DCXRD, and RF device characterization.
