External Fellow

I am Associate Professor at the Institute of Statistical Mathematics, the Research Organization of Information and System, Japan. My main interests are statistical inference of point processes and its application in statistical seismology. I focus on constructing point-process models for describing and forecasting the process of earthquake occurrences. My research areas are recently extended to Bayesian analysis, data assimilation in geophysics, and criminology.
