| Lecturer
in Food Engineering and Research Assistant |
1987-1994
|
Taught undergraduate and graduate
level Food Science & Engineering courses, including lab work.
My Ph.D. research project
was on the development of a computer-vision system for obtaining the weight of live aquaculture
fish from video images taken as they were pumped through a transparent
tube. Conceived and optimized an image-to-weight algorithm that would work
for live fish viewed from any angle, designed and built the fish imaging
system, and experimentally proved that this computer-imaging system would correctly
estimate the weight of the live fish with an error of less than 1.0% (versus
previous methods with accuracies of only within 15%).
During this period also did extensive bibliographic research on omega-3 fish oils, food colloids
and macromolecules, surimi extrusion, and computer control of aquaculture
facilities.
During this period
also worked on engineering design and economic evaluation projects
for private industry companies, such as,
A) the design for a plant to produce
surimi, omega-3 rich fish oil and liquid fish fertilizer from menhaden,
for Sea Resources Engineering, Inc., Kirkland, WA,
B) the re-design of
processing lines for seafood repackaging and distribution, including the
design of new, value-added products, for the Orca Bay Seafood Company,
Seattle, WA,
C) the design of an aquaculture facility using geothermal water for the production and processing of nine million pounds per year of tilapia, for New World International, Inc., Seattle, WA, and,
D) the
technical evaluation of a plant for the production of fish protein concentrate,
FPC, for Rimarsa, S.A., Lima, Perú.
