My research focuses on how communication processes shape and are shaped by collaboration practices across professional boundaries. More specifically, I study the role of communication in interprofessional collaboration in health care, both in primary and hospital care. I am particularly interested in how collaborators define the care situation and how they collectively navigate the multiple definitions that are often simultaneously at play, given differences in professional epistemology, organizational and institutional status, and relationship with patients. I am also interested in the role of the patient or client within the context of collaborative care.
