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!

I'm a working MEP engineer, currently building Python automation for Revit workflows daily - plan checks, model coordination, and repetitive drafting tasks. I teach other engineers, architects, and BIM professionals how to do the same, using pyRevit and real project workflows, not toy examples.

Topics include:
pyRevit fundamentals and setup
Automating repetitive Revit tasks (model checks, plan generation, data extraction)
Writing custom scripts for your firm's specific workflows
Applying Python automation to real MEP/BIM projects

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.

I’m a SideFX Certified Instructor and 3D artist with 20 years of experience in CGI. I offer one-to-one online Houdini lessons tailored to your level, interests, and goals.

If you’re new to Houdini, we can start with the interface, nodes, attributes, and the principles of procedural modeling. If you already use it, we can focus on VEX, simulations, lighting and rendering, or building more effective procedural workflows. I can also help you understand and troubleshoot a project you’re working on.

Lessons are practical: we’ll work in Houdini together, and I’ll explain the reasoning behind each step so you can apply what you learn independently. Before our first session, tell me about your experience and what you’d like to achieve, and I’ll prepare a lesson around it.

Engineering tutoring up to Master's level. I have completed a PhD in Aerospace Engineering. I developed a new type of electric propulsion for spacecraft. I have also published two research papers. I was a university employed teaching assistant for two years, helping third-year aerospace undergraduates complete their third-year group project.

I offer bespoke tutoring sessions. You provide your course material/past exams that you need help with, and we'll work through it together. We'll identify the topics that you would like tutoring in, and I'll help you understand them in an enthusiastic and stress-free environment.

MATLAB help also available!
