The role that carries concepts from research into production and evidence from production back into research; a scholar-practitioner as an institutional position, not a personality.
The term comes from Linda A. Hill, Emily Tedards and Jason Wild, Genius at Scale: How Great Leaders Drive Innovation (Harvard Business Review Press, 2026), and the research programme behind it. They name three roles that innovation at scale depends on: the Architect, who builds the internal capability to cocreate; the Bridger, who cocreates across organisational boundaries; and the Catalyst, who mobilises an ecosystem beyond the firm. What defines the Bridger is influence without formal authority, exercised between organisations with vastly different priorities, constraints and work styles.
I adopt the role and narrow it to one boundary: the one between research and practice. The loops do not run themselves; they need people who understand both worlds. The literature keeps rediscovering that gaps close through people and organisations holding dual citizenship: working in the middle, scholar-practitioners as translators, boundary organisations with standing. The bridge is bidirectional by definition: concepts flow into production, and evidence flows back into research, which is the part the theory side cannot do for itself.
The practising Master is not branding. It is the empirically indicated position from which realisation work is done. See the operator file.
