About Me

Hi I am Dimitrios! I love games, cycling and nature. I live in Rotterdam in Holland, but I grew up in Athens Greece.
I was born a Technologist, and I was trained to become a Psychologist! With a hacker’s mindset I enjoy understanding systems and sharing my knowledge. In essence, I like to break things, explore how they function, and create meaningful stories about them.
I used to hate studying, but I came to love it when I realised I can “hack” it, by making it a social activity! So, come learn together!

My super powers cover a wide variety of topics, like…
how to make your computer obey you
how to study and organise time
how to design research on human behaviour
how to gather data, choose scales, conduct analysis, report results, create graphs
how to “hack” Excel and SPSS and other tools

A highly experienced Franco-Belgian teacher (ook in het nederlands!) offers private lessons in mathematics (including finance), probability and statistics, as well as physics, chemistry, and biology for secondary and higher education levels. For physics, chemistry, and biology, the instruction is tailored to the secondary level, specifically up to the 5th year of secondary education in Belgium.

Whether you prefer lessons at your place, my place, or remotely, I am flexible to accommodate your needs. If necessary, I can travel to your home in Brussels, Walloon and Flemish Brabant, with a minimum duration of 2 hours per session. The lessons are designed to provide extensive practice with numerous exercises. Distance learning options are also available through platforms such as Skype, Facebook, etc. Please note that for students in France, only distance learning courses are provided.

In mathematics, I specialize in various topics and frequently provide lessons covering the entire secondary school curriculum, including math 6 and higher. These topics encompass factorization, equations of the 1st and 2nd degree (with in-depth study of parabolas), limits, derivatives, integrals, exponentials and logarithms, as well as trigonometry. Additionally, I am occasionally called upon to teach analytical geometry in space, including equations of lines and planes.

For statistics and probabilities, I provide instruction in descriptive and inferential statistics (univariate and bivariate), covering confidence intervals and hypothesis tests, applicable to secondary and higher education levels.

Feel free to reach out to me to discuss and arrange the lessons based on your specific needs and availability. My aim is to help you enhance your skills effectively and provide personalized instruction. By tailoring the lessons to your requirements, we can ensure rapid progress in your studies.

I am a Doctor of Psychology and researcher.

I am specialised in Clinical Psychology (reading disability/ dyslexia), although I have good knowledge in other fields of psychology, as well as research methodology and data analysis (expert in SPSS). I would love to help students with the knowledge I have in individual live one-to-one sessions online via Skype/Zoom. I can also recommend literature on a particular subject and send something I already have in my database.
