astronomy; observational astrophysics; supernovae; transients; stellar populations; instrumentation
I completed my PhD at the University of Tokyo in 2013. Afterwards, I briefly worked at Kavli Institute for the Physics and Mathematics of the Universe (IPMU), University of Tokyo, before moving to Universidad de Chile as a FONDECYT Postdoctoral Fellow. I moved to Finland in late 2016 for a postdoctoral fellowship at the Finnish Centre for Astronomy with ESO (FINCA), University of Turku. I am now an Academy of Finland Research Fellow at the Department of Physics and Astronomy at University of Turku.
