He obtained Ph. D from Division of Applied Bioscience, Graduate School of Agriculture, Hokkaido University in 2005, under the supervision of Prof. Atsuo Kimura and Prof. Seiya Chiba. He joined the group of Prof. Birte Svensson at Enzyme and Protein Chemistry, Department of Systems Biology, the Technical University of Denmark as post-doctoral fellow (2007) and assistant professor (2008-2010), working on chemoenzymatic synthesis of oligosaccharides by glycoside hydrolase of GH36 [1] and phosphorylases of GH94 [2] and GH65 [3, 4, 5] catalysing transglycosylation and reverse phosphorolysis, respectively. His recent research interests concern structure and function of Carbohydrate Active enZymes, enzymatic synthesis of oligosaccharides showing healthful effect on human intestine, antibacterial activity, and immunostimulatory activity.
