I am a postdoctoral researcher at the Department of Mechanical Engineering at University of California, Berkeley working with Prof. Ken Kamrin. Previously, I completed my PhD in Civil Engineering also at Berkeley, advised by Prof. Kenichi Soga. Before coming to Berkeley, I obtained my bachelor’s degree in Civil Engineering from Kyushu University in Japan and a master’s degree in Computational Mechanics from the Technical University of Munich in Germany.

My research interests are primarily focused on multi-physics and multi-scale coupled problems in geomechanics, including their mechanical theory, modeling, and numerical simulation using high-performance computing. This encompasses geomechanics challenges across various confinement levels. Specifically, my key research areas include:

  1. Deep geomechanics involving fluid injection and extraction, such as CO2 sequestration, energy extraction, and the stability of rock formations, addressing issues like borehole failure on a local scale and induced seismicity on a larger scale;
  2. Surficial geomechanics, with an emphasis on climate- and earthquake-resilient geostructures, particularly those subject to erosion in river or coastal environments;
  3. Extraterrestrial soil modeling, rheology and their multiphysics interactions with human-made objects.

Throughout my research career, I have developed substantial expertise in computational solid mechanics and fluid dynamics, particle-based methods (MPM, SPH, DEM), contact and interface treatment, coupled formulations, and constitutive modeling. I am always eager to explore innovative approaches for applying mechanics and numerical methods to design safer and more efficient engineering systems and infrastructure.

In my free time, I enjoy reading, camping, hiking, and photography.
