Arnold Hayer

Arnold Hayer is an Associate Professor in the Department of Biology at McGill University. His research focuses on Molecular, Cellular and Developmental Biology, with an emphasis on cytoskeletal dynamics during cell migration, polarity signaling, and vascular morphogenesis. His interdisciplinary approach integrates live-cell microscopy, fluorescence-based biosensors, microfabrication, and computational image analysis to study mechanisms controlling cell behavior and tissue organization. Hayer's work explores how cells are organized into tissues through collective and autonomous motility.

Arnold Hayer is an associate professor at McGill University specializing in cell biology with a focus on collective cell migration, membrane traffic, and vascular morphogenesis. His research explores the molecular mechanisms underlying cellular processes such as caveolae biogenesis, endolysosomal sorting, and signaling pathways regulating directed cell migration. Hayer's work integrates advanced imaging techniques and computational modeling to study dynamic interactions between membrane trafficking, cytoskeletal remodeling, and cellular behavior. His publications highlight the role of ubiquitination, vesicular transport, and signaling molecules like STIM1 and Ca²⁺ in shaping cellular dynamics and tissue formation.
