Assistant Professor of Faculty of Engineering, Information and Systems, University of Tsukuba.
Member of Omote Lab.
I received my PhD in Informatics from the Institute of Information Security (IISEC) in 2022.
I was fortunate to have been supervised by Professor. Akira Otsuka and his passion and generosity continue to inspire me today.
