He is also a Visiting Clinical Researcher in the Department of Natural Sciences at Middlesex University London.

In 2019, Dr Hassan received the British College of Aesthetic Medicine (BCAM) Quality Research Award for his clinical paper, Injectable Platelet-Rich Fibrin for Facial Rejuvenation. His joint research articles have also been recognised with 1st, 2nd, and 3rd place awards in 2023, and a 2nd place award in 2024, by BCAM. His research, which primarily focuses on developing educational tools as well as in regenerative treatments, platelet-rich derivatives (PRF/allogenic growth factors), oral surgery, sedation, and dental implants, has been recognised with several awards, including the Blizard Institute Award for Outstanding Contribution to Education (2024), Outstanding Clinical Tutor Award in Oral Surgery at QMUL (2024), Teaching Innovation Award from the Faculty of Medicine and Dentistry at QMUL (2025), and President and Principal’s Prize for Educational Excellence (2025).
