Hi there!
Let's start with my names... The easy part (at least for Greeks who can pronounce it :-) is my last name: Papadimitriou. My official first name is Ioannis (yeah, I know, too many vowels at the beginning, but actually it's not so difficult), which is the Greek word for John. Nevertheless, everybody calls me Yanni. Since this is the most common Greek name, I mixed things together and now a lot of people call me jpg, which are the initials of 'Johnny Papadimitriou the Greek' (no relation to the JPEG image compression format). Thank God, I don't have a middle name...
Born and raised in the so-called S.S (southern suburbs) of Athens - Greece, I quickly developed a strong inclination towards the new technologies. In 1994, I entered the Electrical and Computer Engineering department of the National Technical University of Athens and completed the five-year curriculum in just four years, having majored in Telecommunications. In the next couple of years, I did my military service and worked as a research assistant in the Telecommunications Laboratory of the National Technical University of Athens (for more information, please download my resume).
Then, I took the 'great step'. I left my family, my friends, the picturesque Aegean islands, the 'frappé' coffee and the famous Greek 'mousakas' behind and decided to go for a Master's degree in the Electrical Engineering Department of Stanford University. In September 2001, I reached the U.S. West Coast and since then I have met so many people from different countries and cultures, studied really hard (it seems to me that this is what people should mean by 'Californian madness' :-), visited a lot of interesting places, such as San Francisco, Seattle, Santa Cruz, L.A., San Diego, Santa Barbara, Las Vegas and Grand Canyon and became part of the American way of living. While working towards my graduate degree at Stanford, I was not alone: my brother, Iakovos, is studying in the Mechanical Engineering department of Berkeley University. Apart from this, I had three scholarships from the Fulbright Foundation, the A. S. Onassis Public Benefit Foundation and the Gerondelis Foundation.
Now that my coursework at Stanford has been completed, it is about time to go one step further. Starting from January 2003, I am with World-Link Telecom Inc., working as a network planning engineer. My primary focus is on improving the quality of voice services we provide over TDM and VoIP infrastructure. It is an interesting period full of changes: from school to a real job, from California to New York City...
