Hi there
My name is René. I combine sound academic expertise in chemistry and biochemistry with over 10 years of teaching experience (more than 5 of which were successfully online). I already hold a Bachelor's degree in Food Technology (grade 1.7) and am currently completing my second Bachelor's degree in Chemical Biology at TU Dortmund (grade 1.8), after which I will immediately begin my Master's degree in Chemistry.

My primary focus is on organic chemistry, particularly organic natural product synthesis, retrosynthesis, organic catalysis, and organometallic chemistry. My bachelor's thesis at TU Dortmund was on the topic of "Synthesis of a substituted 2,3-dihydrofuro[2,3-b]tropone as a model compound in studies on the total synthesis of marine tetraterpenoids of the gukulenin family." To further my scientific expertise, I am currently taking four specialized master's modules at Ruhr University Bochum with Prof. Gerald Dyker: Stoichiometric Organometallics, Catalytic Organometallics, Designing Organic Syntheses, and Competing Reactions. In addition, I have excellent grades in physical chemistry (1.3 in PC 1 & 2 and 1.7 in quantum mechanics/PC 3) and a strong foundation in biochemistry.

In my teaching, I emphasize a deep, logical understanding rather than rote memorization: I explain organic reactions from the ground up using molecular principles such as MO theory, the HSAB principle, quantum mechanics, and pKa values. I place particular emphasis on the precise distinction between thermodynamics and kinetics – for example, when differentiating between basicity and nucleophilicity – in order to make reaction pathways such as nucleophilic substitutions or eliminations predictable.

Over the past 10 years, I have successfully guided numerous students of chemistry, biochemistry, medicine, pharmacy, and engineering through their most challenging exams. My students regularly achieve top marks in written and oral exams, and I am happy to provide feedback and references upon request. Whether you need preparation for demanding university exams or advanced study at the master's level, please feel free to contact me so we can easily arrange an initial consultation.

If you're looking for an organised and professional teacher to help you achieve your academic goals, look no further! The IB science subjects can be extremely difficult to go through on your own, and I'll be glad to use my experience to help you out.

A couple of things I like to do:

- Initial test or interview to assess your level.
- Use Notion as a platform to share all my resources.
- Use mock papers that lay out the exercises JUST like in the real exams, so you will feel really prepared.
- I give homework when appropriate.
- I provide any kind of mentoring and college counseling. People who study Biology and Chemistry usually want to pursue a clinical career-- and that is a complex process!

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.
