Childhood

I was born in Montreal, Quebec, on January 14, 1974, in a French-speaking family; my father is a now retired police agent, and my mother is an artist and an ergotherapist. I started programming at the age of 12 on a TRS-80 Color Computer, on which I learned (all by myself) the basics of computer programming. Until the age of 16 I had much trouble learning English, but after a summer camp in Scotland and in England, I got much better (although I still speak with a thick accent).

At the age of 15 I suffered a second/third degree burn on my right hand, which forced me to write with my left hand for half the school year; I was forced to stop drawing for a long time.

I was never strong in arithmetics; one of my teachers once told me: "You can't multiply properly, but you certainly know how to doodle in the margins". Despite these limitations, I managed to "discover" differential calculus by myself at the age of 16 (using my own notation); this puzzled my Physics teacher. When a high school Math teacher "taught" us that there was no notation for describing prime numbers in a simple way, I came up with a simple definition that used set notation and first order logic. He couldn't refute it, although he pretended that my definition was unusable (!)

At the age of 17, I started losing interest in drawing and painting, and got interested in poetry and philosophy. Since then, I have been more interested in words, grammars and logic; I have lost much of my initial interest (and proficiency) in geometry, vectors and calculus. An interesting side note: as a kid, I wanted to become a geologist. It is only when I read about the employment opportunities, which were at an all-time low in the 80s in Quebec, that I decided to become an urbanist (in the doldrums in the 80s too), then an architect. Unfortunately, I miscalculated by trajectory and ended up as a software architect instead.

College and Undergraduate Studies

After two mediocre years studying Science ("Sciences Pures") in Collège Ahuntsic (I eventually failed two courses and had to re-pass them during the next 2 summers), I entered Université de Montréal in Computer Science. I was initially rejected due to my low grades in college, but after an incredible stroke of luck, I got caught in an open political war between the department's secretary and the dean, and got accepted. Thanks forever to Mady K. for that invaluable gift.

I got brilliant grades in most of my undergraduate courses (Baccalauréat), most notably 11 consecutive "A+" grades in 2nd and 3rd year courses. I was respected for my unusual approaches at solving classic problems, my habit of eating during courses, and my weird sense of humor (I once sent wav snippets to random SGI IRIX stations across the department for 2 days before I got caught).

In 1995, I have participated in a "Useless program competition" with a program named GENCORE, which purposely crashed and generated a core dump of the exact size given as a parameter at the command line. The winner of the competition, though, invented the network mouse driver (which allows the user to move his mouse on multiple networked desktop computers)... which is as useless as it gets!

I won the department's animated Christmas card competition with a 3D renderer written hastily in Simula 67. It was painful and fun at the same time.

I once sequestrated Professor Nie in his office for 2 hours, until he corrected 3 major errors which were made by his assistant in an expert system engine in Prolog. I had discovered the errors after more than 48 hours of non-stop debugging; I was becoming insane. Luckily, there were no negative consequences to my desperate action. Prof Nie is a real gentleman.

WWW

I am a veteran Internet and Web user; I had the chance to surf the Web when there were about 200 sites (in 1993). I could "get through" the Web during lunchtime. At the time, the Web was very disconnected (few links between sites), but there were a few "directories of everything". As it grew bigger and more varied, search engines appeared. My tiny (puny?) personal web page was indexed for the first time by Lycos, then by AltaVista, in late 1995.

I programmed my first Web application in 1995; it was a crude C UNIX program which transformed text documents with minimal formatting (such as "end of page" markers) into a collection of interconnected HTML pages. I programmed my first CGI script in 1997; it was a C program wrapped in a C shell script, which compiled results from an HTML survey page.

The browsers I used so far: a forgotten early browser on X-Windows, then Mosaic (compiled by myself in my UNIX account!), Lynx (through dial-up modem, pre-SLIRP/PPP), Netscape, Explorer, Opera, Firefox, Konqueror.

Graduate Studies and Research

In 1996, I was admitted in a graduate course (Master's Degree)... no question asked! A funny side note: there were spaghetti stains on my admission form, but neither Paul Bratley nor Neil Stewart noticed when they endorsed it.

My Master's thesis covered multiple topics in the field of Artificial Intelligence (AI), more precisely Intelligent Tutoring Systems (ITS). I was a prolific author (as far as MSc students go) and provided almost 100% of the original ideas and content for most of the articles I published. Topics I covered in my thesis and articles are wide-ranging:
1. Assessment and use of cognitive dissonance in collaborative learning
2. Meta-rules for the evaluation of curricula and knowledge structures
3. Unsupervised clustering of student profiles for the initialization of student models and attribute selection
4. Data structures for the dynamic representation of knowledge (with forward/backward propagation of information), mostly in the student model (overlap of the curriculum)
5. Evaluation of student comprehension based on indirect indicators (and not purely "by grade"; it is almost considered an heresy in education science, though)

I took a course in bioinformatics, and made an interesting project in evolutionary programming, which involved the evolution of simulated lunar lander modules (it also featured load-balanced distributed computing, using up to 10 SPARCstation computers in the labo at night).

I have also written a pretty good essay on the philosophical consequences of the Barcan formula (concerning mostly the concepts of identity, uniqueness and distinction). I have studied modal logic, temporal logic, agent logic and fuzzy logic, among other systems.

My thesis received the highest possible grade. I continued making fundamental and applied research at the university even after I finished my MSc, although I was considered a "freelance researcher"; I didn't ask for a salary, only for a copy of the published articles (the proceedings), and I was glad to offer my ideas and insights. However in 2003 I was overworked and on the verge of depression, and I couldn't keep the pace; I was also in a strong ethical disagreement with one of the researchers over some aspects of the research work, so I ended my collaboration.

I was an invited member of the AIED Society in 1997-1999. I was an invited member of the ACFAS in 1999-2000. I have been an ordinary member of the FIQ since 2001.

Current Research Interests

I had been doing some personal research work in number theory since late 1999, and I was exploring some interesting properties of prime numbers. However, after the traumatic incident described below, I had to put it aside for a few years. Mathematics have become even more laborious, but I am patient.

I was victim of a brutal attack while walking on the street in Montreal at night, in early 2000, which left me with permanent damage in the right ear. At the time I had a broken nose, contusions, a few broken ribs and a large hematoma on the side of the head. I still suffer from persistent tinnitus, attention disorder, sleep disorder, fatigue and sometimes dizziness.

I have only resumed this "side project" in 2006. So far, I have produced a very simple proof that all complex primes in N are located on the y=4x+3 line (I love simpler proofs and Occam's Razor is my best friend). I have also explored complex primes and their properties, although till recently I had only rediscovered known properties. I am currently working on some original (and more advanced) work in number theory, which I won't disclose here (of course).

I have kept folders full of handwritten notes about some unfinished works in Intelligent Tutoring Systems, most notably concerning information propagation in curricula, backward-forward propagation algorithms (feedback loops and dynamic equilibrium in information structures), and indirect (holistic, inferred) student evaluation; I may revive these ideas someday in a new research paper.

I also work on the hybridation of neural nets and cellular automata, along with genetic programming techniques; and on so-called "lamarckian" propagation of information structures in virtual environments, using concepts of physical distance and meme permeability in individuals.

Professional Activities

I have been working in the IT industry since 1998. I had to start working a full-time job before I had finished my Master's Degree for economic reasons; my research scolarship was about to end.

I worked in the development of web services, in teledetection (vehicle tracking systems using satellites, ground-based cell network and ionospheric short-wave emitters) and in natural language processing (analysis and classification of corporate/contact information). I also developed a nearly flawless HTML parser, and quite frankly it is much more difficult than it looks like.

In 2005-2006 I worked as a technology consultant; I have helped more than a dozen IT/electronics companies getting funding for their research & development efforts. In particular, I was pleased to help a company which is developing a groundbreaking ITS system.

I currently work mostly as a technical translator (English to French) and technical writer for the IT industry, although I also do some professional web development in PHP.

Recently, I started tinkering with XHTML and AJAX.

Belief System

I don't believe in luck, destiny or predestination. I think a powerful force named "randomness" stirs our lives; people we call "lucky" are the ones who pay attention to these subtle movements. We are not all born equal, and there is no natural justice; however, we encounter plenty of opportunities in life.

I am an outspoken Agnostic, but I am interested with a lot of spiritual approaches ranging from Stoicism to Reformed Christianism. I believe mostly in Humanism; I don't firmly believe in any specific social, moral or political system, although I carefully choose my side at every election.

Travel and Culture

I have traveled to England, Scotland, Spain, Andorra, France, Brazil, India, Switzerland, Austria, Croatia and Hungary. So far, the best food I had on the road was: southern indian food in Delhi, Spanish dry sausage and ham in Murcia, coffee at the Barcelona airport & Zurich airport, and an excellent moquequa in Caraguatatuba. The worst things that happened in my travels was: suffering from a tropical fever in Ubatuba and finding fly eggs in my feet sores (after having to spend 3 days unprepared in the jungle).

I speak a few languages but I don't have any specific talent in learning human languages. I am especially bad at conjugating verbs in any language (including French). However, it didn't prevent me from working as a professional translator (English to French) in technical fields such as IT, engineering, the cars/trucks/trailers industry, electricity and marketing.

I cook quite well and I have a good culinary culture; my friends say that I can't live without 25 spice jars. I love wine, Scotch and "alcools du terroir" (local alcohols, such as cidre de glace, mead and maple alcohols). My favorite wines are those from Alsace (whites), Spain (reds), Italy (reds mostly), Minervois (reds), Madiran (reds). I don't like wines that are too sweet, too dark or too obvious; I think most modern wines are way too concentrated (14.5% alcohol, obvious use of oak flakes, the sweetness of prune juice and the color of concentrated pomegranate punch).

I write poetry (in French) and I am best known for my haiku, which have been dubbed "classy yet fresh". Although I haven't published any poetry book featuring my own creations, I have initiated and produced a project involving 22 poets (some famous, some still young, some obscure) and two visual artists; the book bears the title "Sur les récifs - anthologie avec 22 poètes naufragés"; 400 copies were printed, of which more than 250 were sold and 50 were given away. Sadly, I have stopped writing poetry since 2003 because of a lack of time and energy; I hope to be resuming my artistic production soon.
