Biography and Research Interests
Mar. 2018 : B.E. in Engineering of Information Science at University of Fukui
Mar. 2020 : M.E. in Engineering of Information Science at University of Fukui
Mar. 2023 : Ph.D. in Advanced Interdisciplinary Science and Technology at University of Fukui
Apr. 2023 - Present : Assistant Professor at Iwate University
I am currently an assistant professor in Faculty of Science and Engineering at Iwate University (Japan), where I work with Prof. Yoshihiro Hagihara. Before that, I received my Ph.D. in Advanced Interdisciplinary Science and Technology at University of Fukui, and my B.E. and M.E. degrees in Engineering of Information Science at the same institution, all of which were under the supervision of Prof. Chao Zhang.
My research interests lie in pattern recognition, computer vision, and various other aspects of machine learning.
