Before he was appointed Deputy Chief of Mission at the U.S. Embassy in New Delhi, he served as the Chargé d'affaires and Deputy Chief of Mission for United States Ambassador to Azerbaijan from July 4, 2009 through July 2010, when the office of the Ambassador to Azerbaijan had not been filled yet. He was one of proponents of immediate appointment of US Ambassador to Azerbaijan.

He had previously worked as staff assistant to Ambassador Frank Wisner and as the political officer covering Kashmir and India-Pakistan relations in late 1990s.
