Takeshi obtained his Ph.D in Chemistry from Durham University, U.K. in 2011, where he conducted research in Professor Kosmas Prassides group. His research focus was on investigation of the structural, electronic and magnetic properties of C₆₀-solids.

His first post-doctoral research was at School of Chemistry, University of Edinburgh. While he continued to search exotic phenomena of carbon molecular solids, he shifted from C₆₀ to the family of electronically-active polyaromatic hydrocarbons to discover new carbon-based molecular superconductors.

He then moved to China, where he joined the high pressure research group in Institute of Physics, Chinese Academy of Sciences (IOP-CAS), followed by X-ray Science group, HPSTAR. His current research interest is to alter and improve functionality of carbon-based molecules both by chemically and physically. By combining high-pressure technique and chemical control of crystallization, he discovered various interesting optical properties from simple organic molecules that can be an important discovery for application in various optoelectronic materials.
