Toshu An is an Associate Professor in the School of Materials Science at the Japan Advanced Institute of Science and Technology (JAIST), affiliated with the Nanomaterials and Devices area and the Research Center for Empathetic and Symbiotic Technology with Nature. He earned a B.S. in 1995 and an M.S. in 1997 from Waseda University, followed by a Ph.D. from the Toyota Technological Institute in 2000. His professional experience includes positions as a JSPS Research Fellow at the Toyota Technological Institute, researcher roles at JST, a research fellowship at the University of Tokyo, an assistant professorship at Tohoku University, and a researcher position at RIKEN prior to joining JAIST.
An leads the Laboratory on Quantum Sensing and Imaging, with research focused on quantum spin dynamics, sensing, control, and imaging. His work emphasizes nanoscale magnetic field sensing using nitrogen-vacancy centers in diamond, spintronics, nano MRI, and related phenomena such as spin waves and magnon currents. Key publications include “Scanning diamond NV center magnetometer probe fabricated by laser cutting and focused ion beam milling” (Journal of Applied Physics, 2021), “Probing Thermal Magnon Current Mediated by Coherent Magnon via Nitrogen-Vacancy Centers in Diamond” (Physical Review Applied, 2021), and “Long-distance excitation of nitrogen-vacancy centers in diamond via surface spin waves” (Applied Physics Express, 2017). He has received the JAIST President’s Award for External Funding Encouragement (2019) and the JAIST President’s Award for Research Activity (2016). An maintains affiliations with the Japan Society of Applied Physics, the Physical Society of Japan, the Magnetics Society of Japan, the Surface Science Society of Japan, and the American Physical Society.
