H.E. Ambassador Sylvie LUCAS

On September 16th, 2016, Ambassador Sylvie Lucas presented her Letter of Credence to President Barack Obama.

Prior to her appointment as the 14th Ambassador of the Grand Duchy of Luxembourg to the United States of America, Ms. Lucas served from August 2008 to August 2016 as Ambassador, Permanent Representative of Luxembourg to the United Nations in New York.

From 2004 to 2008, Ambassador Lucas held the position of Director for Political Affairs in Luxembourg’s Ministry of Foreign Affairs, notably during Luxembourg’s Presidency of the European Union in 2005. In this capacity, she was responsible for bilateral political relations, EU common foreign, security and defense policy, NATO, international and regional organizations such as the United Nations, the OSCE, or the Council of Europe, as well as for issues like human rights and rule of law or non-proliferation and disarmament.

The Ambassador also held the post of Deputy Director for Political Affairs from 2000 to 2003. Before, she served for five years as Luxembourg’s Deputy Permanent Representative to the United Nations in New York, beginning in 1995. Ms. Lucas has furthermore served as Luxembourg’s Ambassador to Portugal (2003-2004), and, simultaneously, as non-resident Ambassador to Cabo Verde.

She began her diplomatic career in 1990, when she joined her Foreign Ministry’s Directorate for Political and Cultural Affairs. From 1991 to 1995, she served in the Directorate for International Economic Relations.

Throughout her career, Ambassador Lucas has been particularly focused on issues of international peace and security, peacebuilding, development and human rights. In 2009, Ambassador Lucas served as President of the Economic and Social Council of the United Nations (ECOSOC). In 2013-2014, she was the Representative of Luxembourg on the UN Security Council during Luxembourg’s first ever mandate as non-permanent member of the Council and held the Presidency of the Security Council in March 2014. During Luxembourg’s mandate on the Council, Ambassador Lucas chaired the Council’s Working Group on Children and Armed Conflict, striving to mainstream the fight to end and prevent grave violations against children into the work of the Security Council. From February 2011 to August 2016, she assumed the Presidency of the Guinea Configuration of the United Nations Peacebuilding Commission, an illustration of Luxembourg’s strong commitment to peacebuilding. From October 2015 to August 2016, Ambassador Lucas served as Chair of the Intergovernmental Negotiations on Security Council Reform, upon appointment by the President of the General Assembly.

Ambassador Lucas’ tenure in Washington DC will be an opportunity for her to contribute to the further strengthening of the bilateral relations between the United States and Luxembourg in all fields, political, economic and cultural, trade and defense, as well as between the United States and the European Union, drawing on her extensive experience and specific fields of expertise.

Ms. Lucas was born on 30 June 1965. She received a Master of Arts degree in history from the University of Human Sciences in Strasbourg in 1988, and a Master of Arts in European political and administrative studies in 1989 from the College of Europe in Bruges, Belgium.
