1. Assistant Secretary-General for Supply Chain Management (ASG/OSCM) at

the UN

• Simplifies and automates supply chain processes.
• Advises and supports client entities on supply chain issues.
• Oversees procurement, logistics, uniformed capabilities support, and global support centers.
• Leads crisis preparedness and response for supply chain needs.
• Ensures a nimble, effective, transparent, and accountable supply chain across UN operations worldwide.
• Reports to the Under-Secretary-General for Operational Support

2. Assistant Secretary-General in the Office of Internal Oversight

Services (OIOS) at the UN

• Supports the Secretary-General in oversight of resources and staff through audit, investigation, and evaluation.
• Assists in managing OIOS operations, including risk-based work planning and resource optimization.

The role involves high-level decision-making, coordination across departments, and ensuring effective delivery of services aligned with organizational goals.
