About Me

Passionate about the environment and biodiversity. I have a PhD in environmental sciences and am an expert in the study of planktonic populations (phytoplankton and zooplankton), especially taxonomy and morphological and molecular species identification. Through my research and international experiences in France and Spain, I have developed advanced expertise in data analysis and plankton taxonomy, water quality, ecotoxicology, the functioning of aquatic ecosystems, biostatistics, bioinformatics, ecology, environment and sustainable development.

In parallel with my scientific work, I have a great interest in teaching and sharing knowledge. Having acquired a solid command of French, Arabic and English, I wish to support learners in their linguistic journey through an interactive and immersive approach. My goal is to make language learning accessible, stimulating and adapted to the needs of each individual.
I worked for 4 years as a part-time teacher at the university, in the faculty of medicine and biology. I also have more than 3 years of experience in teaching support courses in foreign languages, mathematics, physics and science for students.
In addition, I provide training in the identification of freshwater plankton and taxonomy, as well as in bibliographic research and the use of Mendeley and EndNote software, writing scientific articles, etc. I have also provided training and freelance work in statistical analyses applied to ecology and biology.

Need help with math and science (physics, chemistry, etc.)? As a 33-year-old civil engineer, I'm happy to help! I'll learn at your own pace, using plenty of examples to illustrate the material. I have years of experience teaching both simple and complex subjects.

The lessons run as follows. First of all, together we look for the student's biggest stumbling blocks. These can be related to the subject matter as well as to the study method. From there, I continue to work at the pace of the student and encourage them to ask as many questions as possible. I also give them tips and tricks, and improve their working methods where necessary. During the lesson I give many examples to make the subject matter more interesting and we solve exercises together. Once the student has mastered the exercises from the lesson, I give some more challenging exercises to also test on the deeper understanding of the subject matter. In this way I try to optimally prepare the student for his / her test or exam.

However, learning should also be enjoyable. That is why I always strive for a good relationship with the student through a spontaneous and positive approach. I am also very patient. All this lowers the barrier to ask questions and improves the student's learning process.

Are you interested? Do not hesitate to contact me!
See you soon!

For many years, I have successfully supported Swiss students in the fields of statistics, data analytics, machine learning, and artificial intelligence. I have gained extensive experience using R as a statistical programming tool and know exactly what students in Switzerland are required to do. I have numerous sample projects, datasets, and exam questions at my disposal and have prepared many students for their assignments and exams in a targeted, sustainable, and highly successful manner. My focus is on explaining complex statistical procedures, algorithms, and data analyses in an understandable way, demonstrating them in a practical way, and building confidence in the secure handling of data. My goal is not only to improve grades, but also, in the long term, to develop a deep understanding of data-driven questions and modern technologies such as machine learning and AI, which are crucial in later professional life.

► How do I teach?

►I attach great importance to ensuring that my students truly understand statistical concepts, data analytics methods, machine learning, and AI models, rather than just applying them mechanically – this is how we achieve sustainable success in statistics, data analytics, and modern technologies.

►My success is based on my ability to flexibly adapt my teaching style to the individual needs of students in statistics, data analytics, machine learning and AI, including topics such as regression methods, logistic regression and other machine learning algorithms.

►I use practical, lively examples from statistics, data science and AI to clearly explain abstract concepts such as hypothesis testing, analysis of variance, linear and nonlinear models and to anchor them deeply in the memory.

►With patience and clarity, I break down complex statistical analyses, machine learning models, and data processes into their essential components so that no student is overwhelmed and can build a solid foundation in statistics, data analytics, and AI.

►I am convinced that trusting collaboration is crucial to reducing uncertainty in statistics or data science and creating a productive learning atmosphere.

►I offer intensive exam preparation and project support in statistics, data analytics, machine learning and AI, develop strategies to combat exam anxiety with my students and train them on real data sets and complex algorithms.

►As an experienced online tutor for statistics, data analytics, machine learning, and AI, I use modern tools such as interactive whiteboards and live coding sessions in R to make teaching as efficient and practice-oriented as possible.

►Locations: I teach statistics, data analytics, machine learning, and AI at your home, online, or by appointment – flexible, professional, and tailored precisely to your needs.
