I have been contributing actively to various scientific communities in terms of peer reviewing, chairing, programme committee and volunteering. I value the opportunities to work with international scholars of different backgrounds and cultures. Along the way, I visit, host and collaborate with many distinguished colleagues across Europe, Asia, and US.

As the co-founder of FCN series since 2014, I have been building and strengthening this international community to promote active collaborations between top European and Asian institutes, including Cambridge, Delft, Helsinki, Leuven, London, Munich, Oslo, Stockholm, Vienna, EPFL, MPI, IMDEA, HKUST, Tsinghua, Peking, Fudan, and Chinese Academy of Science (CAS).
