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 6 years of experience teaching Physics and Maths to kids from unprivileged backgrounds both in a homework schools as well as via private teaching. In private teaching, I have experience tutoring people with learning disabilities (ADHD, Dyslexia, Discalculia and more), younger kids of ages 7-12 and older students preparing for their final baccalaureate exams in advanced maths/physics curriculums.

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!

Dynamics is a branch of physics and engineering mechanics that studies the motion of objects and systems under the influence of forces. In this course, students delve into the principles governing the behavior of particles and rigid bodies in motion. Topics covered include kinematics, which describes the motion without regard to its causes, and kinetics, which focuses on the forces causing the motion. Students learn Newton's laws of motion, the principles of work and energy, and the concepts of impulse and momentum. Additionally, they explore rotational motion, including angular velocity, angular acceleration, and moments of inertia. Through theoretical study and practical applications, students develop the ability to analyze and predict the motion of objects and systems, essential for fields such as mechanical engineering, aerospace engineering, and physics.

Transitioning from learning data science theory to solving actual business problems is the hardest step for any aspiring data professional. [Insert Chosen Course Title] is an intensive, mentor-led program designed to simulate a real-world data team environment. Instead of working through synthetic, pre-cleaned textbook datasets, you will take on messy, complex industry scenarios and turn them into end-to-end data products.

What You’ll Experience

End-to-End Execution: Walk through the full data lifecycle—from problem scoping and data extraction to exploratory analysis, modeling, and executive stakeholder presentation.

Industry-Standard Workflows: Work with messy real-world datasets, practice Git-based version control, write production-ready code, and structure reports that business leaders actually care about.

1-on-1 & Group Mentorship: Receive continuous code reviews, architectural feedback, and project guidance mirroring the experience of working under a Senior Data Scientist or Analytics Lead.

Portfolio-Ready Deliverables: Graduate with 2–3 complete, polished projects that demonstrate actual business value to hiring managers—not just another churn prediction copy-pasted from Kaggle.

Who This Is For
Aspiring Data Analysts, Data Scientists, and recent graduates who know Python, but want the practical experience, confidence, and portfolio needed to land high-impact roles in the industry.

### Courses in Mathematics, Physics, Chemistry and Engineering Sciences

As an engineering student in **mechatronics and instrumentation**, I offer private lessons tailored to the level and objectives of each student, **from middle school to higher education**.

My approach is progressive, clear, and geared towards understanding. The goal is to enable the student to **understand the concepts, master the problem-solving methods, and gradually gain autonomy**, rather than simply memorizing formulas.

**Mathematics:** algebra, functions, derivatives, integrals, differential equations, matrices, probability and statistics, with exercises adapted to the student's level.

**Physics and Chemistry:** mechanics, electricity, electromagnetism, thermodynamics, waves and physical phenomena, as well as the basics of chemistry. Concepts are explained through examples and concrete applications.

**Mechanics:** kinematics, statics, dynamics, energy, strength of materials, mechanical systems and modeling.

**Electricity and Electrotechnics:** electrical circuits, fundamental laws, direct and alternating current, electrical power, three-phase systems, electrical machines and basics of electrotechnics.

**Electronics:** electronic components, diodes, transistors, amplifiers, analog and digital circuits, as well as the basics of embedded systems.

My background in **mechatronics engineering and instrumentation** allows me to link different disciplines and offer a concrete approach through examples from **industry, automation, mechanical and electrical systems and instrumentation**.

Depending on the needs, the courses can be devoted to **understanding the course material, exercises, preparing for exams and tests, refresher courses or further study**.

Each session is tailored to the student's level in order to gradually build an effective working method and genuine autonomy.

As a civil engineer with an EPFL degree, I have been working in a design office since 2020: excavations, retaining walls, foundations, numerical modeling, and site supervision. I mentor junior engineers and interns in this role, and I write reports explaining these calculations to clients who are not engineers.

I support students from EPFL, HES and vocational schools in the branches that filter: statics, strength of materials, reinforced concrete, soil mechanics and foundations.

We work on your past exams and series. For geotechnics and foundations, I show you how these calculations are actually carried out in the office and according to which standards, which makes the material much more understandable than a formula learned by heart.

I also cover technical professional maturity and preparation for admission to a University of Applied Sciences.

Tools I use daily: PLAXIS, GEO5, K-REA, AutoCAD and reading execution plans.

Online courses with a shared whiteboard, or in person in the Neuchâtel region.
