Edward Dolman is stepping down as the executive director and acting chief executive of the Qatar Museums Authority, a job he held for three years, the authority announced on Sunday. But he will remain a member of the authority’s international advisory board.

“I feel it’s time to refocus my life in London and New York,” Mr. Dolman said in a telephone interview.

As the authority’s chief executive, he worked alongside Sheikha al-Mayassa Hamad bint Khalifa al-Thani, the organization’s chairwoman and the sister to the new emir, helping devise a 10-year plan to open a network of museums in Doha. In addition to the six-year-old Museum of Islamic Art, designed by I.M. Pei, several other new museums are in the works, including the National Museum of Qatar, designed by Jean Nouvel, and the Orientalist Museum, designed by the Swiss architects Herzog and de Meuron.

Mr. Dolman has also been involved in acquiring and preserving the collections of the state as well as helping to start educational programs. He has overseen a public art program and a schedule of exhibitions like a major retrospective devoted to the British artist Damien Hirst last year and a giant show of the sculptor Richard Serra that opened last week.

Before running the Qatar Museums Authority, Mr. Dolman was a 27-year veteran of Christie’s, where he served as the chief executive and chairman until his departure for Qatar in 2011. He declined to say what he planned to do next.
