Welcome to Constantinos S. Chassapis' web page

Short Bio my photo

I was born in a suburb of Paris, France sometime in the sixties. I was educated in Greece and France. I grew up, in a suburb of Athens, in a vivid and multifarious family environment where my Swedish mother and my Greek father, a cinematographer, infused into me a well-balanced interest about almost everything around me. My grandfather by being an astronomer infiltrated to me scientific notions very early in my life. I live in Athens, Greece, with wife, who is a pianist.

I hold a University degree in Physics (1988, University of Ioannina, Ioannina, North-West Greece). I hold a PhD in Computer Simulation of Physical Systems (2000, Chemistry Dept., University of Athens, Athens, Greece). I hold two MCP certifications and several other IT-related professional certifications (SQL, HP, Citrix, Siebel, etc,.)

I work (since November 2000) in Algosystems S.A., an IT Company based in Athens, Greece, as a New Products Development Manager. I am also writing a book on Quantum Computing. I like writing, teaching, contemplating about Art and building my web site ( Member: ACM (since 1997), IEEE (since 1996).


A work of fiction of mine (a novel under the Greek title HA!) has been published in 2000 by editions Propobos, Stournari 47, Athens.

"An Introduction to Quantum Informatics", Draft version of a forthcoming book Indivicual sampled Chapters can be downloaded below

Current Research Interests

Entropic measures of pre-meaning, Quantum Computing, neural networks, diffusion in simulated amorphous polymeric materials, fractional diffusion equations.

Current effort concentrates on the development of the pre-meaning theory as a new measure for natural languages and symbolic series. A short introduction can be found here

Among various activities on which I have participated during the last 10 years, I pick:

  • Sep - Oct 2000: I participated on the ICANN@Large election procedures. I was placed 28th among 70 candidates with votes originating from more than one European country.

  • Jun - Jul 1995: I was invited as Visiting Research Scholar and worked on Quantitative analysis of X-ray diffraction from superlattices using multi-dimensional optimisation and stochastic simulation at Rutgers University, New Jersey, and at Los Alamos National Lab., New Mexico.

  • Nov 1994 - Feb 1995: I organized and taught a weekly class on advanced scientific computing and I was honoured with the active participation of my co-students at the National Research Center for the physical Sciences Demokritos (Athens, Greece). Parts of the notes from these lectures are now publicly available on my web site.
