Haydelba

I’m Haydelba, a PhD in Chemistry with more than 40 years of experience in university teaching and scientific research in Venezuela and Ecuador. I have been a full professor, graduate program coordinator, and director of multiple research projects in natural products chemistry, food chemistry, environmental chemistry, and chemical oceanography. Who I help: Secondary and high school students who want to pass and master chemistry. University students in degrees such as chemistry, pharmacy, clinical laboratory science, biology, nutrition, engineering, and related fields. Students who need support with thesis work, projects, lab reports, or scientific articles. Subjects I teach: General chemistry Organic chemistry Food chemistry and food safety Environmental chemistry and environmental monitoring Basic biochemistry Instrumental analysis techniques Research methodology and scientific writing My teaching style: Dynamic classes, with a virtual whiteboard and step-by-step problem solving. Clear explanations that connect theory with practical examples. Materials adapted to your syllabus, with emphasis on what is actually tested in your exams. I can also help you write and review academic and scientific papers (structure, content, and style), drawing on my experience as a thesis advisor and referee for scientific journals. If you want to feel more confident with chemistry, book a class with me. We will work calmly, but very effectively, until you understand every topic.
