🌟 Early Academic Pursuits
From an early stage, Dr. Saad Abd-Elkader Hassan demonstrated an exceptional curiosity about the universe’s workings, leading him to pursue a Bachelor of Science in Astrophysics at Al-Azhar University, Cairo, graduating in 2014. His graduation project, centered on the three-body problem, reflected a strong foundational interest in gravitational dynamics and orbital mechanics—key concepts that underpin modern astrophysics. Driven by an enduring passion for space science, Dr. Hassan advanced his academic journey by enrolling in a Master’s program in Astrophysics at the same institution. He completed his M.Sc. in 2020 with a research thesis titled “Suzaku X-ray Studies of Some Active Galactic Nuclei BL Lacertae Type.” This study marked his entry into the specialized field of high-energy astrophysics, particularly focusing on Active Galactic Nuclei (AGN), among the universe’s most enigmatic and energetic phenomena. Currently, he is pursuing his Ph.D. at Al-Azhar University, with a focus on “Some Advanced X-ray Studies of Active Galactic Nuclei Blazars Type,” signaling his continued commitment to unveiling the energetic behavior of distant galaxies and their central supermassive black holes.
