What are those big red books back there on the book shelf?

Currently looking for ways to grease the gears of community affairs.  Neighborhood Emergency Team.  Block captain, neighborhood crime watch, and participant in Portland Block Captain Steering Committee.  Helping out those neighbors who need a little assistance.  Organizing neighborhood events.   Fill-in for executive positions in Neighborhood Association and SW Neighborhoods coalition. 

Speaker with Portland's Y2K Project speakers bureau ("Success through luck & hard work").  Fire station siting committee.   Volunteer guide for Tryon State Park and Hoyt Arboretum, and, formerly, Children's Museum.

(She'll probably suggest that I remove this when she finds out it's here...)  In May, 1990, before she became quite active in public affairs, Keturah was awarded the "Mayor's Spirit of Portland" award by Portland Mayor, Bud Clark.

Background: Degrees from Iowa State University and U. of Calif. Berkeley (MS).  Major: Botany (plant taxonomy).  Director of Latch Key Day Care Centers (YMCA).

Currently trying to find ways to improve understanding of the science that has made such a difference in human cultures and could make a big difference in personal lives...if only it were understood.

Also trying to find ways to stay in good health as the seventh decade of life ends and the eighth begins...some time in the first year of the new millennium (that's a puzzle:...born in??).
Making accurate maps of streets and trails of the west side of Portland.  Furnishing walkers, runners, Emergency Teams, planning committees, etc with accurate maps of streets, trails and stairs.  Assembling maps and descriptions of walking/running routes in Southwest Portland for placing on Web sites.

Seeking ways to encourage walking, running, and biking in the city for health, for keeping an eye on the neighborhoods, for meeting  the neighbors, for learning the where and what of the neighborhoods, for encouraging community in the neighborhoods, for promoting wellness, and for the fun of it.

Enthusiastic distance runner and weight lifter...but age-related slowing down is beginning to inhibit and interfere.   However, remember that "running raises HDL, and lifting lowers LDL."   Seems to work!
Background:  Several degrees from Colo. Sch. of Mines and U. of Calif. Berkeley (PhD).  Major: Metallurgy and Materials Science.  Minors: Physics and Mathematics.  Semiconductor research, Hughes (Aircraft Co.) Semiconductors.  Teaching physics (and systems science), Portland State University.  Design of curriculum and evaluation materials for several educational agencies.  Author and photographer of Sierra Club film, "Glen Canyon." Design of numerous techniques for stereoscopic imaging (including, in 1972, the random-dot construction of images "hidden" in repetition-stripes and revealed by stereopsis).

Research topics (and patents): dislocation imaging; nomographs for controlled dopant distribution in semiconductor crystals; ultraprecision orientation (crystal) in semiconductor single crystals; precision optical orientation of silicon; crystal-structure-determined etching of silicon structures; semiconductor lenses for infrared imaging; plastic and elastic strain in lithium fluoride; nuclear quadrapole resonance studies of ionic crystals under anisotropic strain; faceting and growth kinetics, with and without dislocation-assistance, in gallium (a first in growth kinetics); evaluation of textbooks and teacher-written objectives in K-12 physical science (leading to published sets of objectives).
