Hello students! Do you find it difficult to learn science subjects, especially chemistry? This may be because chemistry contains some difficult or complex concepts or terms. If you are one of these, do not worry!! Hello and welcome to you, my students, in the right place to solve this problem through simplifying science lessons, especially chemistry. Through these lessons, we will learn together how to deal with difficult-to-understand matters and terms, because I have extensive experience extending to more than 15 years in conveying complex concepts in a clear, easy and simple way. My goal is to make science and chemistry in general and organic chemistry in particular wonderful and understandable for everyone. As a dedicated teacher, I create an interactive and stimulating learning environment for my students using the latest methods. I am ready to share my passion and guide each student towards excellence and success in the field of science and organic chemistry and in studies in general, as I work as a student advisor in an international institution. In addition, I have excellent communication and presentation skills and am patient and calm when teaching. In addition, I constantly follow up on my students' progress and regularly evaluate their understanding through continuous solution of objective questions, as I care more about understanding than memorization. On the other hand, I also maintain good follow-up with parents. My teaching approach is directed towards achieving the highest results, with a focus on helping students understand and master information.

For university students or master's and doctoral students, I teach the course of natural product chemistry or phytochemistry. In this course, we will learn about the methods of extracting, separating and identifying the chemical form of active chemical compounds (biologically active secondary compounds) from natural sources, such as medicinal and aromatic plants. We will also discuss what is known as chromatography, spectroscopy devices, spectroscopy, mass spectrometry and magnetic resonance analysis. In addition to knowing some important applications of these active materials in various fields, such as the pharmaceutical industry, agriculture, etc. We will also learn the practical methods that are carried out in the laboratory to conduct toxicity, antioxidant and diabetes analyses, etc.

Finally, "for those interested in scientific research" there is a course dedicated to knowing what scientific research is, how to choose a research point, how to write scientific research and how to find the appropriate journal for publication and everything related to this topic.

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 curricula.

With my qualifications and experiences, as I hold a master's degree and a doctorate in organic chemistry (chemistry of natural products), in addition to other postgraduate certificates and a doctoral scholarship in pharmaceutical sciences in Belgium from the Erasmus Mundus organization affiliated with the European Union.
