Prof. Kiga is a professor at the Department of Electrical Engineering and Bioscience of Waseda University since 2016, Japan. He was an associate professor the Department of Computational Intelligence and Systems science of Tokyo Tech. There, he coached iGEM teams who got Track awards three years in a row. He completed his Ph.D. at Department of Biophysics and Biochemistry at the University of Tokyo. He has focused on the synthetic biology of genetic code and artificial genetic circuit in microorganisms. His research group is highly interested in Biology-by-Design. By model-based combination of macromolecules, he has implemented artificial genetic circuits to understand design principle of living systems. Also, he has shown that the number of amino acids in a genetic code can be increased or decreased. In FY2015, he has been awarded the Japan Society for the Promotion of Science (JSPS) PRIZE, titled "Construction of Artificial Life System by Synthetic Biology".
