معرفی
Dr. William S. Trimble is a Senior Scientist and Head of the Cell Biology Program at the Hospital for Sick Children, affiliated with the Department of Biochemistry at the University of Toronto. He earned his Ph.D. in 1987 from the University of Toronto, studying ras oncogene mechanisms, followed by postdoctoral work at Stanford University where he discovered the VAMP protein—a foundational component of the SNARE membrane fusion machinery.
His research employs multidisciplinary approaches to investigate membrane-cytoskeleton interactions, focusing on four primary areas: (1) Septin cytoskeleton roles in cell division, migration, and cancer; (2) Primary cilia formation and signaling in development and disease; (3) Scavenger receptors (CD36/SR-B1) mediating lipid transport in atherosclerosis; and (4) SNARE proteins and NSF ATPase regulators in membrane fusion, particularly neurotransmitter release.
His publications (2010–2014) demonstrate a consistent focus on cytoskeletal dynamics, membrane trafficking, and signal transduction, with advanced methodologies including structural biology, live-cell imaging, and single-molecule analysis. Trends highlight septin biochemistry, receptor endocytosis, and lipid transport mechanisms.
Awards and Honors:
- Fellow of the Royal Society of Canada (2006)
- Canada Research Chair in Molecular Cell Biology, Tier 1 (2005–2019)
- CIHR Investigator Award (2000–2005)
- MRC Centennial Fellowship (1987–1990)
He actively advises graduate students and co-supervises doctoral candidates in projects spanning cell biology and biochemistry. His lab at the SickKids Research Institute utilizes mammalian models (mice, zebrafish) and advanced biophysical platforms.
