In the name of Allah, prayer and peace be upon our Prophet Muhammad (peace be upon him). Dear visitors, I am pleased to welcome you to the website of Department of Physics and Astronomy, which is one of the oldest departments of the Faculty of Science at King Saud University, where its establishment corresponds with the establishment of the College in 1373 AH (1958 AD). The Department is proud to include a selection of eminent faculty members: professors, associate professors and assistant professors from the most prestigious universities in the world who work hard to achieve the vision of our wise leadership and in the development and prosperity of our beloved kingdom. They serve the department at all three levels: bachelor, master and doctorate. The department is active in the following research fields namely theoretical physics, nuclear physics, medical and biophysics, materials science, laser and spectroscopy, renewable energy and environmental physics and astronomy. Our mission at the Department of Physics and Astronomy is to raise the quality of university education and perform high quality scientific research in the fields of high importance.  We strive in contributing to the achievement of the objectives of our college and university in order to fulfill the vision of our beloved kingdom by 2030. My personal goal as the head of the department of physics and astronomy is to contribute in raising lifting the status of the department in all fields and develop the learning process for our students by providing them with the knowledge of physics and develop their practical and theoretical skills.  This would enable them to explore their potential and make the best use of it in order to enter the labor market.  They would be highly efficient and contribute effectively in the building of our precious kingdom.
