Brief bio — who am I?


See also current projects.

Was born in Portland, Oregon, raised in Estacada, Oregon. Graduated Estacada High School in 1980. Family was dad, mom and her parents in Newport, Oregon, oldest brother Marvin, then Larry, sister Janice, and finally, me. Estacada is at the red dot, left. In Clackamas County. About 30 miles southeast of Portland.

Estacada is a lumber town rough thirty miles southeast of Portland. Beautiful area. Probably had a population of around 1500 when I was growing up there, recently broke 3,725. New York City, look out. Town now has a synagogue.

Mt. Hood, Oregon, from Trillium Lake

Starting 1980, attended Portland State University for three years as a chemistry major, switching to Oregon State University (OSU), first in computer science, then as an ultimate mathematics major, finally getting two degrees from OSU – mathematics and an combo degree OSU offered called Mathematical Sciences that combines math, computer science, and statistics. Having the right credits and only needing another class or two, did it.

Oregon, rain pouring, on the Pacific.

Yes, it rains an awful lot in the  west-of-the-Cascades Northwest. And, borders on the Pacific, who gives us all that rain. Have many memories of watching the sun set, over the Pacific.

Douglas Fir, grows all over west Oregon

                Douglas Fir: They are everywhere, in rainy, volcanic West Oregon. 

Much east of the Cascade Mountains is high desertBasalt: all over, including at Lava Butte, which we upped in a car, several times, when I was a kid. Lava Butte erupted, perhaps 7000 years ago? Geologically, a young ‘un.

A logging truck

What the Estacada is, or at least was, about: lumber. Growing up there, logging trucks were something one accepts as part of reality, and sees nearly every day.

Crown Point in the Columbia Gorge, close to Estacada. The Columbia Gorge is the only “easy” way cross the Cascades, but the storms don’t appear to know that. Rain pours. A lot. A heavily wooded area. Was there, many times, hanging out at areas like Multomah Falls, Oregon’s highest waterfall:


The General Sherman Tree in Sequoia National ParkRanchos Self-Service Flowers, Portland, where Dean once worked

After OSU … first job was in a dishpit, in Giant Forest, in  Sequoia National Park. Climbed Mount Whitney, the highest mountain in the USA’s “Lower 48.” Then at Rancho Self–Service Flowers that no longer exists (above), in Portland, Oregon. Was on an “island,” sandwiched between Burnside, Morrison, and 20th Avenue; that’s 20th, in front.


A hitch-hiker's thumb. To me, that brings back such memories; how can I describe it when I can't understand what I saw, in my high-hiking years?

Then in Yosemite Valley, where met Peggy, who lasted about four months. We left Yosemite, ultimately landing in Wyoming, where in Shoshone, she decided to dump me. Had little money, and, in short, when she left me on a road outside Casper, and I hitchhiked to Portland, Oregon. Thus began over three years on the road, hitchhiking thousands of miles and living out of my backpack, also spending two winters a ski bum in Colorado, traveling by whatever means I could — hitchhiking, busses, trains, and by one other means that is best not here discussed. Guess I was not “respectable,” and rare speak of the time.

There are no photos of me doing this, so stole a photo of someone’s right hand. Just looking at that photo fills my mind with conflicting memories, of things I saw that can not be described.

As consequence of years living out of a backpack, I laugh at “voluntary simplicity.” Don’t need to read Jack KerouacI lived it.

And, if you never hitchhiked, you will never understand. Forget it. Only those who hitchhiked understand it. I don’t claim to understand it. Never again do I wish to experience what I lived. It’s over.

Cutoff of I-84 from I-80, North Utah, one of countless crossroads out of which I hitchhiked. Headed north, through Ogden, where a cop popped me for illegal hitchhiking. Gave me a “friendly warning” ticket. Put it in a Linear Algebra text, but it later vanished.

Angel Lake, Nevada – didn’t hitchhike there, but didn’t hit or leave by respectable means. This

Angel Lake, Nevada – didnt hitchhike there, but didn’t hit or leave by respectable means. This is a story that will not be here discussed — we broke so many laws, before and after. The ending was not pretty.


A photo from University of Colorado, Boulder, outside the University Memorial Center

Fall 1989 set off to study graduate mathematics at the University of Colorado, in the city of Boulder, also, CU.

Summer 1995 received my Ph.D. in mathematics from the University of Colorado, in the city of Boulder.

                        One shot at CU - Boulder

Six years. A lot of time at a desk. Links to my dissertation and an abstraction I did in Japan are here.


Shortly after my Ph.D., went to Poland to give a mathematics talk, bumming around Poland a month. Giving a talk on my thesis while staying a week or so in Tuczno Castle, swimming in Jezioro Zamkowe, to Wrocław. To Kraków to Wieliczka Salt Mine and less fun, to Auschwitz-Birkenau. Sobering. Through Zakopane to Morskie Oko, where goofed off a few, to Poznań, to Berlin and back.

Japan. Had landed a job there, spring 1995. Later summer, worked for the University of Maryland Asian Division on Okinawa island, spending a summer in Sasebo, just north of Nagasaki), teaching mathematics and computer science to United States military. Yes, in Nagasaki went to the Atomic Bomb Museum, and, stood under the hypocenter. Sobering.

The Three Wise Monkeys, in Nikkō, Japan. Hear no evil, speak no evil, see no evil. With my CU pal Teresa (thanks, Teresa!), saw them


Life on Okinawa Island began to feel … insular. Decided to come home, early 1997. A condition of my contract was that I had to return to “point of origin,” Denver. So, back to Boulder. Had four girlfriends, total; met Colleen Keller, April, 2000.


Colleen and I married, on August 17th, 2002, by the Saint Vrain River at the Folks Fest music festival in Lyons, Colorado. Colleen has no home page as yet.

Orchard Road, downtown Singapore

                                    Orchard Road, downtown Singapore

Did a lot of traveling in my life, glad I grabbed the opportunity to do so:

  • Germany (twice), Poland, Japan (lived there near two years), Thailand (several times), Singapore (net of twice), the Philippines, the Netherlands, England, Scotland, Egypt, later Russia, Beijing and Shanghai. Italy with Colleen.
  • Once went completely round the world with ex-girlfriend Ellen — what a trip. Egypt, pyramids, Karnak, floating down the Nile, to Hurghada. To İstanbul. To India, so much I saw, can’t dream of writing it all here. Nepal. Singapore. The train to Bangkok, the plane to Hong Kong, a plane to Guilin District — so much we saw, novels. Back to the USA.
  • Went round the world a second time, July — August 2009, passing through Russia where I often scarce spoke a word of English for days; Saint Petersburg, Moscow, swam in Lake Baikal. Then China and Japan; blogged the trip here.
  • With Colleen, traveled Italy. Some blogging, of a trip to Maui, is here.
