We had a welcome party for our new technical stuff, Dr. Leiliang Zhen, and for Prof. Roland Fischer from Ruhr University Bochum (Germany), who is now visiting us as a guest professor, plus for Suttipong Wannapaibon, who is a PhD Student of Roland and is working here for collaboration. Occasionally, our friend as well as a collaborator, Dr. Paolo Falcaro from CSIRO (Australia) was visiting us. It was a great party!! Welcome, Leiliang, Roland, and Suttipong, and glad to see you, Paolo!!
