CV

مختصر السيرة الذاتية
I have worked in the field of wildlife conservation for over 25 years, beginning with a 9-year tenure at the prestigious Zoological Society of London. During this time I gained considerable experience in wildlife conservation with a focus on spillover of zoonotic disease. I also have strong laboratory experience in diagnosing diseases that affect wild and domestic animals in Saudi Arabia using modern molecular techniques for disease diagnosis and phylogenetic analysis including PCR and DNA sequencing. Since joining King Saud University, I have been involved in research projects dealing with bats and other mammals across Saudi Arabia. My experience includes: leading field work for sample collection and performing genetic investigations on the isolated organisms on Clostridium perfringens in livestock in Saudi Arabia and comparing with international strains of the organism; PCR, DNA sequencing and immunoassays; participating on a project to produce a vaccine against bacterial haemorrhagic septicaemia of cattle and sheep and performing serological and molecular characterization of the Coxiella burnetti and Pasteurella multocida on camel, ruminant livestock and gazelle samples in Saudi Arabia. Significant participation on a project dealing with MERS-CoV throughout Saudi Arabia. The project involves serological and molecular detection of MERS-CoV antibodies and RNA molecules from domestic livestock as well as wildlife in the Kingdom of Saudi Arabia.
I have also been involved in a project dealing with Arabian oryx (Oryx leucoryx) employing modern techniques in understanding the survival of the Arabian oryx under desert conditions in the Rub al-Khali (Empty Quarter) and Mahazat as-Sayd reserve in Saudi Arabia. I have also studied sleeping pattern in the Arabian oryx (Oryx leucoryx) in Saudi Arabia.
