Dr. Stephen Ferguson’s (CMM) work centres on one of the brain’s most intricate communication systems: G protein-coupled receptors (GPCRs). His research explores how these receptors interact with networks of proteins inside and outside the cell, and how those interactions shape both healthy and pathological signaling. His current efforts focus on metabotropic glutamate receptor pathways and their roles in Huntington’s and Alzheimer’s disease—two conditions where disruptions in neuronal communication have devastating consequences.
A personal beginning
His interest in neurodegeneration traces back to his grandfather’s experience with Alzheimer’s disease. That early experience nudged him toward scientific research and set him on the path to a PhD. Once in the lab, unexpected findings on the regulation of GPCR and glutamate receptor signaling pulled him deeper into the molecular mechanisms that govern brain function. Those “chance discoveries,” as he describes them, set him on a long-term path to uncover how receptor interactions contribute to Huntington’s and Alzheimer’s disease.
The mentors who shaped his path
Although he grew up in a multigenerational medical family, it was his mother who encouraged him to chart his own direction away from clinical medicine. His first scientific break came from Drs. Ron Pokrupa and Antoine Hakim at the Montreal Neurological Institute, who selected him—over many students—to work on brain imaging research. That early opportunity opened doors that otherwise might have stayed shut.
The most defining influence, however, was Dr. Marc Caron, the renowned Canadian scientist at Duke University. “Marc gave me the training I needed to build a successful research career,” Dr. Ferguson reflects. Caron’s mentorship continues to guide his approach to science and collaboration.
