Caitlin Mullarkey

Caitlin Mullarkey is an Associate Professor in the Department of Biochemistry and Biomedical Sciences at McMaster University's Faculty of Health Sciences. She teaches across multiple undergraduate programs including Biochemistry, Biomedicine, and Health Sciences, with courses ranging from Cellular and Molecular Biology to Immunological Principles in Practice and Principles of Virology.

Dr. Mullarkey's research focuses on immunology and virology with particular emphasis on influenza virus immunity, antibody-mediated responses, and vaccine development. Her work explores intricate mechanisms of antibody function including Fc-mediated effector functions, neutrophil responses to viral infection, and the role of broadly neutralizing antibodies. She also investigates innovative approaches to biomedical education through virtual laboratory simulations and online course development.

Analysis of her publication record reveals a strong focus on influenza immunology, with particular expertise in antibody structure-function relationships, hemagglutinin stalk-specific antibodies, and Fc-mediated immune responses. Her work bridges basic immunological mechanisms with practical vaccine development approaches, demonstrating consistent contributions to understanding host-pathogen interactions and immune protection mechanisms.

Scientific Awards:

• Equality of Opportunity Award from the Government of Ontario (2024) for developing and leading McMaster's Biochemistry and Biomedical Sciences Summer Scholars Program

Dr. Mullarkey actively supervises undergraduate research through Senior Research Thesis and Senior Thesis courses, providing mentorship to students across multiple academic years. Her teaching portfolio demonstrates significant commitment to both foundational and advanced topics in biochemistry and immunology. Beyond formal teaching, she leads the Summer Scholars Program which provides full research scholarships to students who identify as Black, Indigenous, and/or 2SLGBTQIA+, addressing barriers to participation in STEM research through comprehensive support for training, mentorship, and living expenses.

As Chair of the Biochemistry and Biomedical Sciences Summer Scholars Program, Dr. Mullarkey has graduated 17 diverse scholars in just two years, with many continuing research at McMaster and receiving competitive awards. The program, supported by McMaster's Global Nexus and Michael G. DeGroote Institute for Infectious Disease Research, exemplifies her commitment to creating inclusive research opportunities in biomedical sciences.
