Interested in civilization study and History, I was traveling to more than twenty countries.
I like also scientific like literature and novels. I am a member of the council board of the Lebanese Cultural Movement.

Education

After getting My Bachelor degree from Lebanon , I went to France where I studied Chemistry at the University of Clermont II and the National School of Chemical Engineering of Clermont-Ferrand France where I was graduated in 1986.
Researcher with more than ten papers published in reputable scientific newspapers.
Actually, I am titled as associate professor.

Experience / Qualifications

After my graduation, I passionately and simultaneously launched into the two fields of education in Africa (Ivory Coast) and industry with my own chemical plant (Plastics, Inks and Coatings in Ivory Coat and Nigeria). Leaving Africa for health problems and returned back to Lebanon, I was appointed director of the Zahrani Power Plant (450 MW) and head of the chemical and environmental department . With respect to my passion for teaching, I was also a part-time professor at the Faculty of Sciences of the Lebanese University. But since 2014, I resigned from the power station and devoted myself for teaching and research at the Faculty of Sciences up today.
Moreover ,I am actually an environmental expert working as consultant for many companies.
I have participated in numerous symposium and conferences around the world as an organizer or speaker. I participated also in numerous scientific talk-shows on national television and author of scientific articles in national newspapers on the themes of energy, oil and gas, environment,..

I am Mavi, a physics engineer working at an aerospace company.
I have been teaching private lessons at the primary, secondary, high school, and university preparatory levels for 11 years. I teach mathematics, physics, chemistry, and science. I have a good command of the curricula of IB, IGCSE, American, Hong Kong, and international schools.

Additionally, I hold the position of president at the Astronomy Society, where I foster my students' interest in astronomy and science beyond the lessons. I prepare the learning environment by incorporating experiments and exploration, moving away from rote education. I often bring experimental materials to class, aiming to make learning memorable through hands-on experiments.

As an educational mentor, I approach my students as if they were my siblings, valuing creativity. I have a deep passion for mathematics, physics, and science. I am dedicated to helping students understand and learn because life encompasses both SCIENCE and ART. The more people I can inspire to know, understand, and love mathematics, physics, and chemistry, the more proud I am.

Are you curious about how nature works?

Struggling with math, physics, or chemistry? You're not alone — these subjects are hard, and classroom explanations are rarely enough.
I offer personalized tutoring for middle school, high school, and early university students following the French Mission curriculum, the Moroccan national curriculum, or the international baccalaureate.
Topics covered:

Mathematics: algebra, geometry, calculus, trigonometry, probability
Physics: mechanics, electricity, optics, thermodynamics
Chemistry: organic, inorganic, stoichiometry, reactions

My approach:
I don't re-explain the textbook — I identify exactly where your understanding breaks down and fix it from there. Each session is built around your specific difficulties, not a preset program.
I completed CPGE (Classes Préparatoires aux Grandes Écoles) in Mathematics and Physics before graduating as a State Engineer — I know these subjects at an advanced level and I know where students typically get lost.
Individual and small group sessions available. Online (worldwide) in French, Arabic, or English.

Hello 😊

Engineer (BAC + 5) in Process Engineering (Physics-Chemistry), I propose today to give you tutoring lessons in maths-physics and chemistry for college, high school and post BAC up to L3 (or special maths). for the prepas) with help in preparing for competitive examinations (Grandes Ecoles or agro/veto).

Since high school, I like to pass on my passion for science to students. Over the past 10 years, I have been able to discover a good number of profiles that I have been able to accompany (for some for 3 years) up to patents, BAC and competitions.

My teaching method is based on several pillars:

- transmit a methodology, because very often it is not a problem of understanding the course that blocks the student but a lack of methodology in the approach to the exercises,

- listening to the student, adapting to his profile, his way of integrating and working, understanding the sciences,

- show popular science or present exercises using examples from everyday life, in order to deconstruct the negative image of science that many students have. In short, show them that science is easy and that we rub shoulders with it everywhere around us at all times :)

- repetition and practice, the main structure of my course: repetition of the previous course to ensure that the concepts have been well integrated, present the course of the session and the formulas and principles to remember (it is at the beginning course that the student's memory and attention are the best), then practice for 2/3 to 3/4 of the course, and finally recap and lesson note cards.

I hope to be able to pass on my passion for science to you soon :)

If you love scientific research, especially in the field of chemistry or pharmacy, but you do not know where to start or do not know the correct methods of scientific research, then welcome to the course dedicated to learning:
What is scientific research?
How to choose a search point
How to write scientific research
How to find the right journal to publish
How to publish in international journals
How to follow up and track research after submitting it to the journal
How to respond to the journal after the research has been reviewed by the referees?

Experience: About 20 years of practical experience in the field of chemistry, medicinal and aromatic plants, and pharmacy, with parallel training and private lessons for chemistry science curricula.

With my qualifications and experience, I hold a master’s degree and a doctorate in organic chemistry (chemistry of natural products), in addition to other graduate degrees and a doctoral scholarship in pharmaceutical sciences in Belgium from the Erasmus Mendus Organization of the European Union.

I offer chemistry lessons for school students, from basic concepts up to high school level, including Organic Chemistry I & II.

As a 3rd-year pharmacy student, I have a strong background in chemistry and a deep understanding of how to explain complex topics in a simple and clear way.

I have previous experience teaching chemistry at my own school, and I truly enjoy helping students understand and even enjoy the subject.

In my lessons, we focus on:
• Understanding concepts step by step
• Solving problems with confidence
• Making chemistry easier and less stressful

My approach is friendly and patient, and I adapt each lesson to the student’s level and needs.

Mastering mathematics and science at lower secondary level (LWS/KS3) is crucial for success in IGCSE.

I explain science and maths concepts easily, so students truly understand the underlying causes and never have to memorise a formula again.

Hello!

I'm a Physics and Chemistry teacher and I've dedicated the last 20 years of my career to teaching at a prestigious Portuguese International School. If you're studying abroad and feel that Physics and Chemistry are a challenge, I'm here to simplify everything and help you shine! 🌟

What sets me apart? My vast experience allows me to understand exactly where students usually "stumble." My classes are 100% in Portuguese, focused on creating a solid foundation and confidence. I specialize in High School and rigorous preparation for National Exams, but I also work with University students who need to consolidate their foundations.

I organize each class in a personalized way: we identify your weaknesses, solve practical exercises, and demystify the theory. My goal is not just for you to pass the exam, but for you to understand the logic of science clearly and easily.

Let's work together to achieve the grades you deserve? Book your class and let's get started!
