Biography

Akira Endo received the Ph.D. degree in astronomy (with "Prize for Encouragement in Research, analogous to cum laude) from the School of Science, University of Tokyo in 2009 with a dissertation entitled "AlN Tunnel Barriers for Submillimeter Wave SIS Mixers." Since 2009, he is working as a postdoc researcher at the Kavli Institute of Nanoscience within the Delft University of Technology in the Netherlands. From November 2014, he is appointed as a tenure-track assistant professor at the EEMCS Department of Delft University of Technology. During 2011-2014, he conducted an NWO-Veni program and a JSPS postdoctoral research program "Probing the Cosmic History of Star Formation by Submillimeter Wave Ultrabroadband Spectroscopy using Superconducting Resonators." He has been granted a NWO-Vidi program starting from 2014 entitled "Dawn of Superconducting Astrophotonics." This project aims at the development and demonstration of a superconducting on-chip filterbank spectrometer DESHIMA, which capitalizes on the collaborative development of MKIDs at Delft University of Technology and SRON Netherlands Institute for Space Research.

Endo's current research focuses on developing new types of instruments, which enable to observe galaxies in the early universe in new ways. Endo takes superconducting electronics and nanotechnology as his main toolbox, as there are still many unexplored properties of superconductors that can be used for detecting light, in various ways and with very high sensitivity.

Endo works together with his local colleagues at the TU Delft (Terahertz Sensing Group and Kavli Institute of Nanoscience), as well as several other national and foreign institutes such as SRON Netherlands Institute for Space Research, Leiden Observatory, Max Planck Institute of Radio Astronomy, University of Tokyo, and the National Astronomical Observatory of Japan.
