Welcome to my portfolio!

I started to write this portfolio at the end of 2002, when I was a first-year mathematics student at Utrecht University. It is designed primarely to keep track of my progress over the years. An up-to date portfolio also was a prerequisite for completing the Bachelor's programme in Mathematics. Furthermore, a portfolio generally is seen as a welcome addition to a Curriculum Vitae.

I have decided that this portfolio be public, so that anyone interested can access its contents freely. Also, for accessability, I'm writing most new content in English, while (on request) I may translate some older content to English.

Feel free to email me at webmaster "at" trancethrust "dot" nl for questions, suggestions, etcetera.

During this year, I finished high school (VWO, N&T) at the Candea College. The Dutch schoolsystem is built so that students can choose pre-defined study paths. The path I took was 'Nature & Science', which included mathematics, physics and chemistry along with other courses obligatory to all students. As an optional course I took Information Technology. Also, I've done 2 years of (ancient) Latin and one year ancient Greek.

Before graduating, all high school students must do a rather big project on the field of one of the chosen path's main courses. I did mine about building a working computer simulation model of our solar system for Physics, together with E. Faber.

I quite enjoyed myself during that project, so the choice on what to do after high school was quickly made; Computational Science (CS) at Utrecht University. Unfortunaly, when I was about to enroll, CS was basically merged into the new Mathematics Bachelor course. So I enrolled there intent on obtaining a B.S. degree majoring in Mathematics with a minor in CS. After that, the master Scientific Computing seemed fun (and also very close to CS).

*Parallel Radiosity*. Also, as the final part of the Masters programme, I am currently doing an internship at Alten Nederland (The Dutch subdivision Alten). My work there consists of researching R-trees for use with oil reservoir simulation software. This project is done for Shell, but Alten is intending to further research internally also.
