Prior to her study in UIC, she had done research on ethical leadership and team dynamics for six years, and had obtained her PhD degree in China. During her study on leadership and teams, she gained insights on how leaders can facilitate intragroup cooperation and team performance through leading ethically and she became more interested in relationship between supervisors and the subordinates. Then, she shifted her research attention to the leader-member exchange and social exchange within a group and their associations with ethical leadership.
