Leslie Harris, the president of the Center for Democracy and Technology (CDT), announced on Wednesday that she will step down sometime before March 2014.
CDT's board has appointed a search committee to pick her successor. CDT is an advocacy group that focuses on Internet freedom, online privacy and free expression.
Harris said she is still determining her next step.
Harris became the group's president in 2005. Under her leadership, the group tripled its staff, opened a California office and put more emphasis on EU policy-making.
"CDT is now well positioned to influence tech policy globally," Harris said.
