Need help with maths or biology?
As a biomedical scientist with a PhD in Medicine and Health Sciences, I enjoy helping students of all ages to better understand the material and learn with greater confidence. We work at your own pace and in a way that suits your learning style.

How does a lesson work?
In the first session, we identify the main difficulties together. From there, we build up step by step. I encourage questions and provide practical tips and strategies to make studying more effective.

We work through exercises together, discuss examples, and then move on to more challenging problems to deepen understanding. This approach ensures you’re well prepared for your tests and exams.

A positive learning experience
Learning should be enjoyable. With a patient, motivating and clear approach, I create a relaxed environment where it’s okay to make mistakes, and no question is too much to ask — because that’s how real learning happens.

Interested?
Feel free to get in touch for more information or to arrange your first lesson. I’ll be happy to help you move forward!

I offer private mathematics lessons for all levels from secondary school (from first to last year) up to university level (bachelor's degree).

A computer science and applied mathematics engineer (PhD in applied mathematics), I am currently pursuing a Master's degree in mathematics. I have also completed teacher training (agrégation) and taught mathematics at Collège Saint-Pierre (Uccle) as well as in two European Schools, in French.

I have the official certificate allowing me to teach in French. Although I am a native Dutch speaker, I can therefore teach without difficulty in French (and also in English).

My goal is not just to help solve exercises, but to truly make mathematics understandable. I pay particular attention to the structure of the reasoning, the clarity of the explanations, and the step-by-step progression.

I particularly help pupils and students who:
– wish to consolidate their bases
– lack confidence in mathematics
– are preparing for an exam or a transition to higher education
– want to deepen their understanding

My method is based on simple, rigorous explanations adapted to the student's level, as well as carefully chosen exercises to develop autonomy, confidence and work methods.

FOR REMOTE COURSES, I USE A GRAPHICS TABLET WITH A STYLUS, WHICH ALLOWS ME TO WRITE AS ON A WHITEBOARD, VISIBLE IN REAL TIME BY THE STUDENT VIA SCREEN SHARING.

Tijdens de Cito-training gaan we actief aan de slag met verschillende soorten opdrachten uit rekenen, taal en begrijpend lezen. We oefenen met echte voorbeeldvragen en kijken samen hoe je die het beste kunt aanpakken. Niet alleen het juiste antwoord is belangrijk, maar vooral hoe je daar komt.

We leren handige manieren om vragen stap voor stap op te lossen. Soms betekent dat dat we een andere aanpak proberen als iets niet meteen lukt. Leerlingen ontdekken wat voor hen goed werkt en oefenen met het aanpassen van hun strategie.

In de lessen werken we afwisselend zelfstandig, in kleine groepjes en samen met de leerkracht. We bespreken antwoorden, vergelijken aanpakken en leren van elkaar. Ook oefenen we met het werken onder tijdsdruk, zodat leerlingen hier vertrouwd mee raken.

Er is veel ruimte om vragen te stellen en extra uitleg te krijgen. Zo bouwen leerlingen niet alleen kennis op, maar ook vertrouwen in hun eigen kunnen.

The best way to learn Spanish is by actively using the language. In this lesson, I help students step by step to improve their speaking, listening, grammar, vocabulary, and writing skills.

The lessons are practical, interactive, and tailored to the student's level and goals. We work with conversations, exercises, role-playing, texts, and everyday situations so that the language becomes immediately applicable. We can also focus on school assignments, exams, pronunciation, or building more confidence while speaking.

I pay close attention to clear explanations and active practice, so that grammar is not only learned but truly understood. Whether you are a beginner or already have more experience with Spanish, the lessons are tailored to your pace and learning style.

My goal is to make Spanish accessible, motivating, and practical, so that students can use the language with more pleasure and confidence.
