BOSTON (AP) — The state's former inspector general is joining the Pioneer Institute, a Boston-based think tank.

Gregory Sullivan will be the institute's research director, focusing on a variety of public policy issues for the conservative-leaning institute.

Sullivan served two five-year terms as Massachusetts inspector general, a position appointed by the governor. The office was created to look into fraud, waste and abuse in state government.

Sullivan, a Democrat, previously served for 17 years in the Massachusetts House of Representatives.

He replaces Steve Poftak, who left the Pioneer Institute last year for a position at Harvard's John F. Kennedy School of Government.
