Passionate & empathetic teacher. I have a Master's in Physics with honors from the University of Leicester (which was featured at the time as a top 5 Physics university in the UK by The Guardian) and a - french - European School diploma in which I achieved 90% in Physics and 85% in Maths.

Helping others understand difficult topics and skills is something that I am very passionate about as an empathetic person. I have experience teaching Physics and Maths to kids from unprivileged backgrounds at the homework school in Saint-Gilles (CASG du Service Social Juif asbl) as well as 5 years of private teaching.

In my classes, I aim to:

- help students achieve better grades in exams/tests in all branches of Physics & Maths
- clearly explain and break down topics
- give context and or example applications of topics (to improve understanding and memorization)
- help with ADHD & other learning disabilities
- give practical advice for university applications (eg. UCAS in the UK) and discuss the exciting Physics research/work and projects you can work on later in life.

Physics has a plethora of useful and fascinating applications, from the detection of Gravitational Waves and Gamma-Ray Bursts to the development of novel Medical Imaging techniques and Nano-technology (eg: smartphones). It is a subject that I am very passionate about and I hope to make use of my years of experience and extensive knowledge to help you understand and love the subject! My lessons will always be tailored to the individual needs of the student, so please do not hesitate to contact me if you have questions!

The TU Delft Aerospace Engineering Bachelor is one of the most prestigious bachelor programmes the Netherlands has to offer. With it being highly sought-after by students all around the globe, there is a highly competitive selection procedure which needs to be completed to get admitted to this popular degree. A massive part of this admission procedure is the selection exam, consisting of three different tests: Mathematics, Physics and First-Year Material.

As a cum laude graduated Aerospace Engineer at TU Delft, who has also been tutoring since 2017, I have a lot of valuable experience and knowledge of the program to help you out with the right preparation to get in. Moreover, after successfully helping more than 10 students secure a spot over the last three years, I have decided to prepare an additional custom lesson plan for each student, based on the admission syllabus, to ensure an even higher chance of admission.

With my calm and stepwise explanation, weaker topics will be addressed, and your solution procedures will be polished. Each lesson will either be theory, exercise-based or an opportunity to talk about the admission, student life, Delft, what to expect from the study and whether it is the right fit for you.

80% of my students got accepted in the 2025 exam, I am sure I can help you out in the 2026 exam!

TU Delft is Europe's most prestigious university for aerospace studies, preparing some of the best engineers. However the selection procedure is tough and demanding, and only those prepared have a chance to succeed.

As a TU Delft student, I know from first hand how stressfull this process is, and can therefore help you succeed in the preparation of these exams. I have previous experience as a tutor back in high school, helping students improve their grades from Cs to As.

Moreover, I have an extensive knowledge on the subjects tested on these exams, having taken them myself, completed the courses at university with excellent grades and teaching over 10 students for the entrance exam.

Throughout the class, I will use a presentation to explain the main concepts of each exam (Maths, Physics and Aerospace Engineering), focusing on those subjects the student is struggling with most. After this, I will help the student complete some practice excercises, and then assign extra practice to complete on their own time. These exercises will then be reviewed in the following class to ensure the topics have been understood.

I am looking forward to help you in your journey as an aerospace engineer!

The classes introduce students to the fundamental principles and problem-solving methods used in math, physics, and engineering, with an emphasis on logical reasoning, mathematical modeling, and real-world applications. Through a mix of theory, worked examples, and hands-on exercises, students learn how to translate physical or practical problems into equations, analyze systems using quantitative tools, and interpret results critically. I focus on building a strong analytical foundation that supports advanced study and equips students with skills commonly used in scientific research and engineering design.

STEM or STEAM involves learning about:
1. Science
2. Technology
3. Engineering
4. Arts
5. Mathematics
The course is developed to give middle school learners a broad, comprehensive overview of these fields of study. Learners are introduced to career planning, so they become aware of the major course competencies that they need to develop. The careers vary from teaching to space studies.

Mini Makers STEM Lab is a hands‐on, online class where young creators explore early engineering, problem‐solving, and imagination using simple materials they already have at home. Each session features a guided STEM project—like paper helicopters, balloon rockets, marshmallow towers, or DIY parachutes—designed to build confidence, fine motor skills, and curiosity.
Kids follow along step‐by‐step on camera, test their creations, make improvements, and share what they built. The focus is on creativity, exploration, and learning through play. This class is warm, encouraging, and perfect for children who love building, experimenting, and making things with their hands.
