Hiroki R. Ueda received his M. D. from Faculty of Medicine, the University of Tokyo in 2000, and received his Ph. D. from the University of Tokyo Graduate School of Medicine in March 2004.While an undergraduate, he worked as a research assistant on a biological simulation system project at Sony Computer Science Laboratories. As a graduate student he next went on to work, first as a researcher (2000) and then as a group leader (2002), at Yamanouchi Pharmaceutical, on a project studying biological clock mechanisms in fly and mouse. He was appointed team leader at the CDB in 2003, and continues to investigate biological mechanisms and phenomena (such as biological clocks) at the systems level, seeking to identify and analyze individual system components and their networked interactions, and ultimately to control existing systems and design new ones.
