Dr. Haijie Tan

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.

During his PhD research, Haijie gained extensive experience in developing advanced electronic devices based on novel 2D crystals including graphene, boron nitride, WS2 and MoS2, and has co-authored 8 publications. He was adviced by Professor Jamie H. Warner; and funded by the Khazanah Global Scholarship.

Haijie is currently a post-doctoral research associate at Hamlyn Centre for Robotic Surgery, Imperial College London working on medical micro-robots and smart sensing technology.
