Why Allergy and Immunology?
I am fascinated by the myriad presentations of immune dysregulation, ranging from allergy to autoimmunity to immunodeficiency. There is great potential for research to further our understanding of the factors that lead to these disease states. From a clinical perspective, allergy and immunology is a highly multidisciplinary area with important links to respirology, ENT, dermatology, and other areas of medicine, and it offers the opportunity to care for both children and adults.!

Research Interests: Allergic asthma

Likes: Sports, exercise, jokes & having fun!

Why Allergy and Immunology?
My initial exposure in this field was sparked by my research experiences as I developed a strong interest in basic immunology. I enjoy the diversity that exists in Allergy & Immunology and the wide range of clinical presentations in both adult and pediatric allergy, autoimmunity and immunodeficiency. I hope to continue to build upon both my clinical and research experiences throughout my fellowship.

Research Interests: Chronic Urticaria, Hereditary angioedema and Microbiome role in asthma control.

Likes: Traveling, organizing social events and cooking

Why Allergy and Immunology?
The key aspects of Allergy and Clinical Immunology that attract me are the intricate physiology, the mix between acute and chronic care, and the care for patients of all ages it employs. I have always aspired to be an expert in this field, and to further contribute to the unveiling of the immune system's many secrets while striving to develop innovative therapies that address related disorders.

  • BMSc, Medical Sciences, University of Western Ontario (2008-2012)

Research Interests: Asthma, prevention of allergic disease, food allergy

Likes: Baseball, golf, travelling, cooking

Why Allergy and Immunology?
I was drawn into this specialty's unique diversity of clinical presentations, from more common allergy and asthma, to rare and complex multisystem disorders. It is especially rewarding to care for such a large population affected by atopic disease and make a meaningful and positive impact on quality of life for patients and their families. Also, it is a unique specialty which allows the opportunity and challenge of continuity of care from pediatrics into adulthood.

Research Interests: Food allergy

Likes: Dancing. All types. It just makes me so happy!

Why Allergy and Immunology?
From the moment I did my first rotation, I knew this diverse field suited me well. It is a subspecialty of not only common food allergies and asthma, but also one that mixes in with rare disorders; all of these stemming from a fine ‘dance’ in our immune system. Also, it is great that I can have the continuity to follow my pediatric patients into adulthood!
