Nikki Sivakumar, Clinical Research Assistant
Nikki got her bachelor of science honors degree with a major in life sciences at Queen’s University. During her time there, she developed a strong passion for immunology and physiology, specifically in exploring the disease development of certain immunologic conditions. This led her to work at an asthma and allergy clinic, where Nikki got to observe these clinical manifestations in real life. She also applied her passion for research development working as a summer student in the community health sciences department at the University of Calgary, where she got to explore novel interventions that may help improve long-term health outcomes of those suffering from diabetes and food insecurity. Nikki hobbies include swimming, traveling, and spending time with my friends and family. Nikki is now pursuing Med. school in Europe.
