Activities and societies
During his time at RCSI, Al-Houssan also participated in substantial research that allowed him to become a co-author and contributor for peer-reviewed, scholarly studies. For almost 3 years, he participated in research involving cat allergy testing. He worked with Red Maple Trials in Ottawa, Canada to validate the first naturalistic cat allergy exposure chamber in the city. The research appeared in the European Respiratory Journal as well as the Journal of Allergy and Clinical Immunology.
