Dr. Manel Jordana

Principal Investigator, MD, PhD

Born and raised in Barcelona, Spain, Dr. Manel Jordana completed his medical training at Universitat Autonoma de Barcelona and continued with a residency and clinical fellowship at Hospital de Sant Pau in the same city. Dr. Jordana quickly developed a passion for scientific research, and pursued this path with determination. After graduating with a PhD at McMaster University, he embarked on post-doctoral studies. He joined the faculty of McMaster University in 1988, and has since supervised over 75 trainees, and co-authored 160 scientific papers, reviews and book chapters.

Jianping Wen

Research Technician

Jianping graduated from West China University of Medical Sciences, China and worked in the same university as a lecturer for a few years. Then, she continued to study molecular biology in Witten/Hedreke University, Germany. Here, as a research technician, she has a key role in the management of the lab, she assisted and worked with all graduate and undergraduate students for their projects bringing her knowledge and experience in the fields of animal work, cell culture, blood process and functional assay, as well as molecular biology.

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.

Favourite Cell: Allergen-specific B cells


Emily Grydziuszko

Masters Student

Emily received her B.H.Sc. from McMaster and originally joined the Jordana lab as an undergraduate student before becoming a Master’s student in May 2021. She works on a project with Josh and Jessica to investigate the role of allergen-specific CD4+ T cells in the incipient phases of food allergy. Alongside Allyssa, Atai, Jessica and Allison, she also investigates allergen immunotherapy in mouse models of food allergy.

Vitoria Olyntho

Undergraduate Student

Vitoria is a third-year student in the Honours Bachelor of Health Sciences program and pursuing a concurrent certificate in Immunology, Microbiology, and Virology. Her project involves using multiplexed immunofluorescence confocal microscopy to investigate the immune microenvironment of the human eosinophilic nasal polyp to elucidate the cellular interactions responsible for the perpetuation of polyposis in chronic rhino-sinusitis patients.

Favourite cell: eosinophils


Jessica Schneider

Undergraduate Student

Jessica is a H.B.Sc Candidate completing her fourth year thesis in the Jordana lab. She loves T cells! She works with Emily to also investigate  the role of allergen-specific CD4+ T cells in the incipient phases of food allergy. She also investigates allergen immunotherapy in mouse models of food allergy with  Allyssa, Emily, Atai, and Allison.

Favourite Cell: ALL T cells (especially CD4+)
