Takahiko Uchide
I am Takahiko (Taka) Uchide, an earthquake seismologist. I aim to understand the physical mechanisms of earthquake generation from the stress loading on and around faults to the dynamic rupture evolution. My approach so far is the data analysis (including deep learning) using seismograms and earthquake catalogs to capture the reality of seismic processes. I am trying to extract information inferred from data as much as possible, and as robust as possible.
Short Bio
Taka earned his Ph.D. at the University of Tokyo, Japan. After postdoctoral researcher positions at University of California, San Diego, USA, and Kyoto University, Japan, he has been working as a Researcher since 2013, Senior Researcher since 2017, and Chief Senior Researcher since 2022 at Geological Survey of Japan, AIST. Currently, he is mainly serving as a Planning Officer at Research Strategy Planning Office, AIST. In the Seismological Society of Japan, he served as a Board Member, Chief Editor of the Editorial Board of the Newsletter, and Chair of the Seismology Summer School 2020. He was awarded Young Scientist Award of the Seismological Society of Japan in 2014.
