Simran Jeet Singh might be the busiest person I know. And he definitely has more Twitter followers than anyone else I know. Simran is an author, a scholar, an advocate for the Sikh community, a public speaker, a parent, a marathoner -- the list goes on -- and he's also the newly appointed Executive Director of the Program on Religion and Society at the Aspen Institute. Revealer readers may also recognize him from his time as our Henry R. Luce Initiative on Religion in International Affairs post-doctoral fellow, or from his articles on the vulnerability of being a public figure and the meaning of service.
