I am Kodai Sagae, a new postdoctoral researcher at Geological Survey of Japan, AIST. I received my Ph.D. at Tohoku University in March 2022. My research topic is to investigate spatiotemporal evolutions of tectonic tremors and to understand the physical process behind them. In this project, I will comprehensively detect slow and fast earthquakes by using machine learning and other techniques to help understand their growth process and generation mechanism.
