Support faculty processes and committees by optimizing use of faculty and leadership time, tracking decisions, following up on actions, preparing clear and timely documentation, and ensuring follow-through between faculty, committees and Executive Leadership.
Coordinate and support cross-functional initiatives led by Executive Leadership, ensuring milestones are met and stakeholders remain aligned.

Executive Leadership Support and Coordination

Strategically manage executive calendars and email to optimize time allocation, align priorities, and preserve flexibility for urgent and emerging needs.
Manage end-to-end travel arrangements, including logistics, reservations, and detailed itineraries.

Team and Organizational Contribution

Operate as part of a pooled Executive Administration team, providing flexible, collaborative support across multiple executives and portfolios based on priority and workload.
Provide backup coverage for colleagues, ensuring continuity of service and a consistently high standard of executive support.
Contribute to the enhancement and continuous improvement of administrative processes, tools, and best practices within an academic and research environment.
Undertake additional responsibilities as required, demonstrating adaptability and responsiveness to evolving organizational needs.
