Gehlbach is an educational psychologist who brings social psychological principles to bear on educational challenges. His research focuses on improving educational settings through enhancing the social interactions of teachers and students. His primary focus centers on social perspective taking – how people discern the thoughts and feelings of others within the classroom. In addition to this substantive interest, he is also interested in helping social scientists to design effective questionnaires. He teaches classes in both of these areas. Currently he serves an advisor to the Strategic Data Project. For the 2014-2015 academic year, Gehlbach is on leave from Harvard to work at Panorama Education.
