Haijie completed his Bachelor's degree in Materials Science and Engineering from Tsinghua University, Beijing. His final year project, supervised by Prof. Yang Shen involved synthesis of photocatalytic BiFeO3-Graphene nanocomposites and their applications in water purification.

In his PhD studies, Haijie has gained experience in developing ultrathin opto-electronic devices based on novel 2D crystals including graphene, boron nitride, WS2 and MoS2 . He is supervised by Professor Jamie H. Warner; and is funded by the Khazanah Global Scholarship.
