Present position

Seismologist, Researcher

Research Interests

My research interests are the observation, monitoring, detection, and characterization of earthquake and slow slip activities in multiple tectonic environments around the world using offshore and land-based seismic data. My study regions predominantly include geothermal areas and strike-slip faults in places such as Japan, the US west coast, western Canada, the Caribbean. In the future, the Sea of Marmara will be included.
