Our Team

Envoys and Fellows

WorldBoston’s Envoys and Fellows Program brings together experienced practitioners and emerging leaders to advance key areas of diplomacy that are central to the organization’s strategic priorities. These areas—whether geographic or sector-specific—reflect domains of growing importance in global affairs and increasing relevance to Greater Boston’s international engagement.

Through this program, WorldBoston collaborates with Envoys — mid-to late-career experts who bring deep experience, specialized knowledge, and established networks within their field — and Fellows, emerging leaders who contribute energy, perspective, and executional support. Together, they work alongside WorldBoston leadership to design and deliver public programming, engage international delegations, and strengthen connections across diplomatic, academic, and civic communities.

The program is designed not only to expand WorldBoston’s capacity, but to actively shape and elevate these priority areas of diplomacy, ensuring that Boston remains a dynamic platform for global exchange and innovation.

Ambassador Circle

WorldBoston’s Ambassador Circle is a curated network of former career U.S. ambassadors who bring diplomatic experience and global perspective to the organization’s work. The Circle enhances WorldBoston’s role as a platform for high-level international dialogue, offering access to experienced voices across geopolitical regions and specific issue areas.

The Circle is anchored by WorldBoston’s inaugural Ambassador-in-Residence, Mark Libby, who serves as the central point of coordination—convening members for select engagements, activating the network in response to emerging global issues, and integrating deep diplomatic and ambassadorial expertise into WorldBoston’s programming. Through this structure, the Ambassador Circle enables a more responsive, elevated, and connected approach to international engagement, reinforcing WorldBoston’s position as a trusted regional convener at the intersection of diplomacy, policy, and civic life.

Leonard Tshitenge

African Affairs Envoy

Originally from the Democratic Republic of Congo, having grown up in Gabon, and now based in Boston, Leonard brings over three decades of cross-continental experience. He is deeply familiar with Francophone African markets and broader regional dynamics.

As Africa Envoy, Leonard will support WorldBoston in strengthening Africa-focused programming and engagement. Africa is home to the world’s youngest population and plays an increasingly important role in global trade, energy transition, agriculture, and technology development.

Claire Noble

Subnational Diplomacy Envoy

Claire Noble joins WorldBoston as Subnational Diplomacy Envoy, where she plays a central role in advancing the organization’s work as a platform for international engagement at the city and regional level. In this capacity, she contributes to WorldBoston’s convenings, recruits and coordinates speakers and panelists, and builds partnerships across the region’s municipal, diplomatic, academic, and civic communities.

Claire's professional body of work sits at the nexus of practice and coordination, connecting foreign diplomats, university experts, public officials, and industry leaders through programs that bring subnational diplomacy into action. She works closely with leading Boston-area institutions—including universities and graduate programs focused on international affairs and public policy—to identify subject matter experts and integrate academic perspectives into WorldBoston’s programming.

Claire approaches subnational diplomacy as a practical and increasingly essential form of global engagement, one that is carried out not only by national governments, but by cities, universities, and regional institutions operating in real time. Through her work at WorldBoston, she contributes to positioning Greater Boston as a hub where these actors convene, collaborate, and engage with international counterparts.

Her background in public service includes work in municipal government in both Dallas and Boston, where she managed cross-sector initiatives and coordinated between government, local institutions and communities. This experience informs her ability to operate across institutional boundaries and coordinate stakeholders with differing priorities. Claire's experience across municipal leadership, stakeholder coordination, and international affairs positions her to enhance WorldBoston’s subnational diplomacy work, strengthening the role of cities and institutions as active participants in global affairs.
