Harikesh S. Wong

Assistant Professor of Biology

Harikesh S. Wong studies how intercellular communication controls the immune response in tissues.

Education

  • PhD, 2016, University of Toronto
  • BSc, 2010, Biochemistry, McMaster University

Research Summary

Immune cells communicate across multiple scales in time and space, forming intercellular circuits that promote or impede the immune response. We employ distinct quantitative fluorescence microscopy methods, computational modeling, and experimental perturbations to study these circuits and their emergent behaviors within intact tissue environments. Ultimately, we seek to understand how imbalanced immune cell communication — due to genetic or environmental variation — results in detrimental host outcomes, including pathogen dissemination, autoimmunity, and tumorigenesis.

Harikesh S. Wong will begin his appointment in early 2022.
