Hideo Iwasaki

Biologist and artist. Director of metaPhorest (biological art/ bioaesthetics platform), Professor, Department of Electrical Engineering and Bioscience, Waseda University. I am interested in the complicated relationship among scientific, philosophical, cultural, historical and aesthetic views of life. In 2007 I founded metaPhorest, an interdisciplinary art/science (bioaesthetics) platform, where both artists and biologists share space for science and art simultaneously. I have studied cyanobacterial circadian clock and morphogenesis, and is a co-founder of the Japanese synthetic biology society (Japanese Society for Cell Synthesis Research).
