This course is designed for students who need to understand immunology, molecular biology, cell biology, and biochemistry from a logical and applied perspective. My goal is not for you to memorize facts, but to teach you to think scientifically: to identify relationships between processes, understand mechanisms, and build a solid conceptual foundation that you can use in any biomedical science course. I work with a clear, structured, and problem-solving style. I explain each topic from its molecular foundation, connecting it to physiology, disease, and real-world experimentation. In this way, the content ceases to be a list of isolated concepts and becomes a coherent system that you can confidently analyze and apply. If you are looking for serious training, with a university focus and guided by a professional with teaching and research experience since 2005, this course will help you master molecular and cellular sciences effectively and permanently.
