Welcome to my profile.
I am an experienced mathematics and science teacher with over seven years of experience helping students strengthen their understanding, improve their results and become more confident, independent learners.
My lessons are designed for students and families who value high-quality, well-prepared and personalised teaching. Rather than offering a one-size-fits-all course, I adapt each lesson to the student’s level, objectives, school programme and learning style.
I teach students who need to rebuild essential foundations as well as those working on advanced topics, examinations or demanding international programmes such as the European Baccalaureate and International Baccalaureate, as well as, the various Belgian programs.

◆ MY TEACHING APPROACH ◆

• • Initial assessment • •
We begin by identifying the student’s current level, strengths, difficulties and academic objectives.

• • Personalised lesson planning • •
Each student receives a structured learning approach based on their specific needs, curriculum and pace of progress.

• • Clear and accessible explanations • •
Complex concepts are broken down into logical, manageable steps, with visual representations and carefully selected examples.

• • Active problem-solving • •
Students are encouraged to think, explain their reasoning and develop reliable methods for approaching unfamiliar questions.

• • Targeted practice • •
Exercises are selected to address specific weaknesses, consolidate knowledge and prepare effectively for tests and examinations.

• • Regular review and feedback • •
Previously studied material is revisited when necessary, and clear feedback is provided to help the student understand what has improved and what still requires attention.

◆ WHAT YOU CAN EXPECT ◆

Professionalism and reliability are central to my work:
• • Lessons prepared in advance and tailored to the student
• • Punctual and well-structured sessions
• • Patient, respectful and focused teaching
• • Clear explanations without unnecessary complication
• • Constructive and timely feedback
• • Adaptation based on the student’s progress
• • A serious learning environment that remains supportive and encouraging

My objective is not simply to help students complete exercises. I aim to help them understand the underlying concepts, develop stronger reasoning skills and gain the confidence required to work more independently.

Mathematics and science can appear difficult when important foundations are missing or when explanations are poorly adapted to the learner. With the right structure, guidance and practice, these subjects become far more logical, accessible and rewarding.

Techniques such as mnemonic devices, visual aids, and real-life examples are integral to my method, ensuring that formulas and concepts are not just memorized, but truly understood.

Regular assessments are conducted to track student progress and identify areas needing improvement. These tests also prepare students for their school exams, ultimately boosting their confidence. I understand the importance of keeping parents informed and involved in their child’s academic journey. That's why I provide weekly reports detailing their child’s progress, strengths, and areas for improvement. This continuous feedback loop ensures that parents are aware of their child’s development and can support their learning at home.

Encouraging words and positive feedback are integral to my teaching method. I strive to build students' self-confidence and to instill a love for learning through positive reinforcement. Setting achievable goals for each student, I celebrate their successes and motivate them to strive for excellence.

I am a PhD physicist and teacher known for being able to explain the most complex topics in the simplest way, from Newton's laws to the high-school student, to quantum physics to the university student.

Teaching focus:
- Fundamental theory: most difficulty in solving exam problems does not come from the complexity of the problem but from the student not being comfortable with the theory.
- Problem solving: breaking a question down into its simplest parts, visualising the physics involved.

Format:
- Lessons at my home where I have a whiteboard and desk set up for teaching
- Online via Google meet
- Lessons at the student home (depending on distance, possible surcharge)

Exams: Any pre-university examination, including Matura, PAM, IB, A-levels. The type of exam is not as important as the topics being studied.

What students say:
- "I had to repeat the first semester of medical school because of physics, and after working with Ralph, physics actually became one of my best subjects. He explained the theory incredibly clearly and went through the exercises step by step. I could ask questions at any time, and I was also able to decide what pace we wanted to work at during our lessons." (Helena, UZH student)

Personal accomplishments:
- Gold medalist at the International Astronomy Olympiad (Beijing 2005)
- Lecturer at ETH Zurich 2020-2024
- Phd in Theoretical Physics, University of Bristol

Format:
- Lessons at my home where I have a whiteboard and desk set up for teaching
- Online via Google meet
- Lessons at the student home (depending on distance, possible surcharge)

Exams: Any pre-university examination, including Matura, PAM, IB, A-levels. The type of exam is not as important as the topics being studied.

What students say:
- "I had to repeat the first semester of medical school because of physics, and after working with Ralph, physics actually became one of my best subjects. He explained the theory incredibly clearly and went through the exercises step by step. I could ask questions at any time, and I was also able to decide what pace we wanted to work at during our lessons." (Helena, UZH student)

Personal accomplishments:
- Gold medalist at the International Astronomy Olympiad (Beijing 2005)
- Lecturer at ETH Zurich 2020-2024
- Phd in Theoretical Physics, University of Bristol
- B.Tech. in Engineering Physics, IIT Bombay
