Welcome Student,

As a graduate of the Bachelor's program in Mathematics and Computer Science and the Master's program in Mathematics, I've noticed that many students struggle with many subjects. These are often also the most crucial for their progress, as many future courses build on them. If you're a Bachelor's student facing the same challenge, you've come to the right place. We'll review the material together and work towards your exams, so you can confidently take them.

From a 'birds-eye view', many of these courses clearly have specific types of assignments that you must be able to pass your exam. We pick out these kinds of assignments and we will train you together in order to master them. In addition, we will counteract your weaknesses by going through assignments and theory about it.

To give you a clear idea of which courses I've taken and how I can help you, I've included a list of my completed university courses below (all with a grade of 7 or higher). Note that I studied in Utrecht myself, so your courses may be titled differently.

I am a certified communication scientist (WO, MSc.) who teaches computational data analysis methods in SPSS, Python, R and thesis supervision.

During the lessons we can cover the basics of computational methods or data analysis. I can also help you gain a better understanding of the data structure, design a questionnaire in QUALTRICS (or similar program), or collect data together with you. We can do this in the programs Python, R or SPSS. I am also an expert in supervising theses.

I give lessons of one hour as standard, but these can be longer if desired. If you are looking for guidance for a longer period, I can offer you a package where you get a discount on my hourly rate.

I have experience teaching computational data analysis and machine learning at university and college level. I myself have a research master's degree in communication sciences.

What is this AI thing everybody is talking about these days? Do you want to understand technology at a deeper level? Are you interested in how common applications fundamentally operate? Would you like to improve your logical and analytical skills (not to mention endurance and patience)?
Learning to code - a phrase that is all too popular nowadays. Still, dealing with programming languages is kind of inevitable in every sector. And by becoming fluent in Python or AI techniques you broaden the spectrum of your possibilities, in academia, in the job market and in your personal life too!
There is simply no better language than Python to begin with on your exciting coding journey. And there is also no better way of doing that than by having someone personal to ask questions to. This way you not only don't have to waste time and effort on a stupid typo, but you're also less likely to give up. Effort * Encouragement = Success!
