Ivan’s private site

Originally, I am a mathematician (graduated in Budapest, Hungary, in 1979), but I turned into a computer scientist after my graduation. I joined the Computing and Automation Institute (SZTAKI) of Budapest in 1979. I then left Hungary in 1986; after having spent 3 years in a private software house called “Insotech Consult GmbH” (which, unfortunately, went down the drain since…) in Munich, Germany, I joined the Centre for Mathematics and Computer Sciences (CWI) in Amsterdam in 1988, as a senior researcher. I also received a PhD in Leiden, the Netherlands, in 1989. I then spent 12 years as a “traditional” computer science researcher working mainly on Computer Graphics. I joined the staff of the World Wide Web Consortium (while maintaining my position at CWI), in January 2001, where I served as Head of Offices until June 2006. Since June 2006 I am Semantic Web Activity Lead. If you want more details on my professional life, you can look at my home page at W3C or my “professional” CV (the latter is just a boring list of projects and references…).

I live in a suburb of Amsterdam called Amstelveen. A decent, but bit of a dull place; its biggest advantage is that one can get to Amsterdam easily!

I am married, and have a grown-up son, David. My wife, Éva, is a researcher in history remotely attached mainly to the Corvinus University in Budapest, while David is currently a student at the Conservatorium of Amsterdam as a classical pianist.

You may wonder about my nationality: well, I was born in Hungary and lived there until 1986 but, due to a complicated family background, I am a mixture of French and Hungarian. I hold both passports, my bedtime stories were French, I made my studies in Hungarian, I have family in both places… As you may imagine, this was still a bit of a touchy situation until the end of the 90’s but, thanks of the changes of the time, today it is merely a curiosity. It is difficult to say which country I really “belong” to, obviously. Although I am probably a bit more Hungarian than other, nevertheless the easiest is to say that I am a European, and that’s about it. This is probably why I have been living in a third country for over 20 years now. As for my age: well, shall we say, I have passed 50 some years ago…

In my free time I love reading literature of all kinds. I also love listening to music. I’m primarily a classical music fan (although, I must admit, my taste seems to be incompatible with most of contemporary classical music). But not only; I like jazz, blues, and I still love to listen to some of the jazz-rock music of my youth. And I’ve also discovered traditional Indian music, which is indeed a fantastic music to listen to. I am also very interested in history and in politics; wherever I am, I try to keep up with the news, I also try to understand local history, cultural backgrounds, etc. I must say that one of the many exciting aspects of my current job is to work with an incredible wide range of people (W3C has offices more than 17 different countries from Australia to the United Kingdom, and from Morocco to Korea; there are also around 15 different nationalities represented in the W3C staff to which I belong!).

Art in general, primarily architecture, classical painting, or sculptures, are among my favorite passtime. I am blessed to live in a city which has a wonderful architecture; and I try never to miss visiting architectural landmarks or major musea when I travel. I also discovered Asian art (mainly Chinese, Korean, or Japanese painting, but also Indian and Indonesian sculptures, for example) a few years ago although I am very, very far from being a connoisseur. The classical Book of the Tea by Kakuzo Okakura was probably one of the readings which made me discover this world, but my several trips to East Asia since have enriched me tremendeously. I believe there are lots of things we in the West ought to learn from there. (I even got inspired in my professional life: some times ago I published a paper with a colleague on what we called “Minimal Graphics” in an IEEE journal. Originally, we wanted to start a European Union research project on this, but it was turned down as industrially irrelevant…). I am also quite fond of the Australian Aboriginal Art although, again, I am really only a naive amateur. But what I saw when I was lucky enough to go to Australia is breathtaking. We in Europe think to have discovered abstract art in the 20^th Century; well, just look at what those artists have been doing in the past few thousand years!

I also like traveling which is, luckily, also part of my job. I have a separate page that lists all places I traveled to since around 2002 (I lost a track a bit, and the data are accurate from 2004 onwards only). I also like photography, so whenever I can, I “steal” some time on my trips to take some pictures. I have put some pictures to this site, just for the fun of it. I am afraid I would fill up the available disc space in no time if I put all my pictures there, though…
