Professional Experience
1996 - present       
Chemical ElectroPhysics Corp.
President
--- founded Chemical ElectroPhysics Corporation and
 negotiated its exclusive license of an in-line
dielectric sensor with DuPont.  
--- developed the commercial Proceptorô analyzer 
and introduced it to the market.  
--- sold and shipped the first complete
system.  
--- developed a database of nearly 600 potential
customers and established a network of sales
representatives and distributors. 
--- established a network of outside resources to develop,
produce and support the instruments. 
--- drafted terms of an agreement with DuPont to add a
wedge rheometer to the license.

1986 - 1996                         
The Dupont Company
Senior Research Physicist
--- led a diverse group of electrical, mechanical, and
software engineers, rheologists, polymer scientists
and technicians through the development and
commercialization of an in-line rheometer that
enabled process engineers to better understand and
control polymer manufacturing processes.
--- characterized process viscometers for automotive
paints, established correlations with laboratory
measurements, and provided an in-line system that
improved quality control.  
--- formed and led the DuPont Rheology Network 
which continues to promote valuable technology 
transfer among the research, production and 
academic communities. 
--- designed an in-line dielectric sensor which
successfully monitored compositions and viscosities
of polymer melts and provided a rugged, corrosion and
abrasion resistant instrument for process measurement
and control.  
--- developed threadline tension sensors,
installed them in textile fibers spinning machines,
and provided data which was used to reduce the
frequency of threadline breakages.

1979 - 1986                         
Kulicke & Soffa Industries
Engineering Supervisor
--- designed piezoelectric transducers and acoustic
systems that allowed faster ultrasonic bonding of
wires in microcircuit packages.  
--- studied resonant frequency variations during 
bonding attempts with and without wires; 
--- supervised one Ph.D. and two
M.S. theses to understand them.  
--- designed, produced and supported over 
200 commercial installations of a system that 
analyzed the acoustic loading patterns and
successfully stopped the bonders when 
the wires fell out. 
--- designed a high voltage power supply which utilize
electronic switches to generate glow discharges
at the ends of gold bonding wires to form balls;
--- achieved a cost savings over the previous expensive
mechanical switches.  
--- developed a hardware system of printed circuit 
boards for wire and die bonders and substantially 
increased production capacity. 

1972 - 1979         
Decision Data Computer Corp.
electronics technician
--- calibrated and repaired keypunches, printers and
other computer peripherals.  
--- designed and built test equipment and software.
