I'm a 43-year old physicist, I live in the greater Zürich area and work in Windisch at Fachhochschule Nordwestschweiz. I studied physics at ETH Zürich, finishing with a diploma thesis in nonlinear optics, did a PhD in solid state physics with Professor H.C.Siegmann and a Postdoc in beautiful Hawaii with Professor Klaus Sattler. When I got homesick in Hawaii I realized that I had to return; which I did in late 2002. Since then I have been working in Professor Heinz Burtscher's group as a research scientist. We specialize in the measurement of aerosols (e.g. particulate matter from diesel cars); using modern aerosol research equipment and on occasion building our own instruments - our specialty is the use of diffusion batteries and ultra-low-noise electrometers for size and number concentration measurements. We devised one of the world's smallest nanoparticle detectors, the Miniature Diffusion Size Classifier, and recently, I started a small spinoff company with Dominik Meier.
Before marriage and kids, I used to play chess a lot, and still play with the team of Wollishofen in the highest Swiss league, but less than previously. I also used to program a lot when I was a bit younger - mostly board games (chess / checkers / 4 in a row / solitaire). My program CheckerBoard is a de-facto standard program for all checkers enthusiasts. I'm working harder on the job now and have more other responsibilities in life, so I program less these days. Whenever I can, I spend my holidays in the alps, skiing or hiking.
So that I don't get too fat and lazy I now go swimming more often than earlier, a habit which I picked up in Hawaii (of course) - from Anne-Catherine - thanks for the swimming lessons! More on Physics, chess, checkers.
In 2006, I got my 15 minutes of fame by appearing on Swiss TV in the program 10 vor 10 on March 13,2006. You can watch the video by going to the 10 vor 10 archive, and there look for the program part called "Dicke Luft in Restaurants" of March 13, 2006)
well, enough talk, enjoy the pictures!

Letizia Antonietti
My greatest programming failure ever! Actually, the program - for the dating agency that our class was running at the 1989 high-school party of the Gymer Neufeld - was just fine. The not-too-difficult special case if girl = Letizia print "The boy of your dreams is Martin" worked as intended, but when she came up to me laughing that I must have cheated I didn't know what to say... pathetic!

Despite lots of work on my checkers program, it finished last of 3 entrants - however with the tiniest possible margin, 2 games lost, one won, and 45 draws. Nevertheless, I still enjoyed my All-American breakfast!
