I have over 30 years of experience as a faculty member at various universities, where I have taught and given lectures in the areas of refrigeration, air conditioning, and renewable energies. I supervise undergraduate students graduation projects and offering consultations in my area of expertise. Numerous of my research papers have been published in national and worldwide scientific conferences and journals. The research articles that were published covered a wide range of topics, such as energy and renewable energy sources, as well as air conditioning and refrigeration systems for different uses.
