Professor Mohammed Hussain AlQahtani is the founder and Executive Director of the Centre of Excellence in Genomic Medicine Research (CEGMR) King ABdulaziz University (KAU) and also the founder and Director of the Genomic Medicine Unite (GMU, KAU Hospital). Dr AlQahtani obtained his Bachelor of Science degree in Medical Technology from King Abdulaziz University in 1989 after which he sought postgraduate Master's study at Michener Institute for Applied Health Science, Toronto, Ontario, Canada and obtained his M.Sc. degree from there in 1992. 

In 1994, Dr AlQahtani added to his profile the NCA qualification in clinical cytogenetics from the National Certification Agency for Medical Laboratory Personnel Bethesda, Maryland, USA and added the CSLT qualification in the same field from the Canadian Society of Laboratory Technologists Hamilton, Ontario Canada. In 1999, Dr AlQahtani was awarded the PhD from the institute of cancer studies, Clinical Oncology Department, the Medical School, University of Sheffield, UK. 

After his PhD, Dr AlQahtani carried out a considerable number of studies in his field and published more than 45 peer-reviewed international articles in addition to giving a considerable number of lectures and talks in international conferences. Due to his outstanding scientific and administrative performance, Dr AlQahtani is appointed in a number of academic positions including a consultant for King Abdulaziz City for Science and Technology (KACST, 2002 until present), Deputy Director of King Fahd Medical Research Centre (KFMRC, KAU, 2002-2006), and a head of the Medical Biology Department, College of Medicine (KAU, 2005-2007).
