Two international conferences, Gordon Research Conference (GRC) on Biomineralization and International Symposium on Biomineralization (BIOMIN), have been held once 2 years so as not to be overlapped to each other. I participated in GRC four times and in BIOMIN five times. I also participated in Pacifichem, Asia Biomineralization Symposium, and other conferences related to biomineralization. Some of my graduate students and postdocs also took part in the conferences and presented posters.
