"Huge progress has been made in Northern Ireland over recent years," she said.
"As the headlines in the past few days demonstrate, however, we still have some way to go if we are to overcome the divisions in society and build a genuinely shared future.
"I look forward to working with the executive, political parties and people from right across the community to build a stable, peaceful and prosperous Northern Ireland for everyone."

Ulster Unionist Party leader Mike Nesbitt: "In welcoming Theresa Villiers, I would like to pay tribute to Owen Paterson who was not only a hard-working secretary of state but possibly the most diligent shadow secretary of state we have ever had. I hope his successor will show the same enthusiasm and commitment," he said.
"I urge her to clarify whether she will be as supportive of the devolution of the powers to vary Corporation Tax to Northern Ireland as Owen Paterson was," he added.
