Dr. Al Qahtani joined the College of Medicine, King Saud bin Abdulaziz University for Health Sciences (KSAU-HS) as assistant professor of hematology in the Department of Basic Medical Sciences in 2015. Before that he worked as a teaching assistant of Hematology in the Department of Pathology at King Khalid University, Abha (2006 -2007). Subsequently, he moved to KSAU-HS as a teaching assistant. Dr. Al Qahtani did his PhD in Hematology & Oncology at the University of Manchester, United Kingdom. As a faculty member, Dr. Al Qahtani is involved in course instruction and additional administrative work. He has been supervising several undergraduate students and has published many articles in journals of international repute. During his PhD program with Hampson’s group, Institute of Cancer Science, Viral Oncology, College of Medicine,  University of Manchester, he had extensive experience in many aspects of both molecular and cellular biology in order to investigate gene function, gene regulation, gene expression, molecular cloning, plasmid construction, quantitative PCR, protein immune-detection and targeted gene silencing. His future plan is to study the role of tumor viruses in the etiology of leukemia.
