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.

As a teaching professional, I have always enjoyed sharing my knowledge. My goal is to provide quality education. I am aware that some topics may seem complex, but often this is simply the result of an inadequate explanation by the teacher. With me, you will discover a real interest in the material!

We strive together to achieve academic excellence, overcoming the shortcomings and difficulties encountered by your child. Studies will become a pleasant experience for him. In addition to the courses, I can also help with school orientation, identifying their preferences and highlighting the advantages and benefits of a fulfilling educational ambition.

The sessions generally take place according to the following stages:

1️⃣ The first sessions are devoted to the assessment of the student's level in order to detect existing gaps.

2️⃣ Next, we create a personalized plan to address these gaps, including the number of hours of work needed, specific areas to focus on, and appropriate training and development exercises.

3️⃣ We stay in constant contact with the student's class teacher, to keep up to date with the latest requirements and ensure a consistent approach.

4️⃣ Subsequently, I provide exams similar to those that are likely to be asked in class, to prepare the student effectively.

5️⃣ Upon request, I write a regular report, usually monthly, to keep parents informed of their child's progress throughout their course.

I adapt my methodology according to the specific needs of each student, thus offering them a personalized and adapted work approach.

In addition, I offer crash courses for students preparing for the start of the school year, allowing them to start the year well prepared, with a solid lead on the school curriculum.

If you have any questions, do not hesitate to contact me. I will be happy to help you.

I have been a statistics teacher now for close to 20 years. First as a teacher at university and for the last 7 years as a private tutor. I like to help people like you actually understand statistics. Statistics is really quite simple, it's just often being explained in an unnecessarily complicated way. If you didn't get anything your teacher said...sometimes that isn't your fault. Sometimes that just means the teacher wasn't able to translate the ideas they were trying to teach you into simple enough words.

It might be hard to believe but statistics can even be fun and it's fun to see people finally get it and start to smile while they are learning :)

I use a professional online environment that allows us to look at slides together, share our screens, record sessions and more.
