Musician; music is my wife.

Mathematics is my mistress; can't leave that girl alone!

Heads up! I advise those who choose to visit my personal website, www.fuckyeah.biz, to be prepared for, shall I say, an alternate form of web experience, one neither presentationally nor navigationally conformal to the Canons of Web Design/Development. I am of course honored that anyone would care to.

I actually have some academic credentials:

B.S. Mathematics, Caltech, 1972

M.S. Computer Science, Caltech, 1981 (no, it didn't take 9 years!)

Ph.D. Electrical and Computer Engineering, University of California, Santa Barbara, 1995

M.A. Religious Studies, University of California, Santa Barbara, 2005

Damn! I am degree'd out!

Being born 17 September 1950, I am told by astrologer friends that I have the sun and four planets in Virgo! That's supposed to be an astrological whammy of astronomical proportions. But who knows? Certainly not I.
