Joshua Koenig

Research Associate

Josh received his undergraduate degree from the Bachelor of Health Sciences program at McMaster University in 2015. He entered the Master's of Medical Sciences program under the supervision of Dr. Jordana and transferred into the PhD program in January 2017. His project focuses on the generation of high avidity IgE antibodies in food allergy. Josh's graduate research is made possible through the scholarships: Ontario Graduate Scholarship-PhD and the Eva Eugenia Lillian Cope Scholarship.


Kelly Bruton

PhD Candidiate

Kelly received her B.Sc. in Medical Sciences and joined the Jordana lab in the summer of 2016. Her project involves the development of a pre-clinical humanized mouse model using PBMCs from allergic patients to study the role of memory cells in the longevity of food allergy.
