Short Bio:
I am a Postdoctoral Associate at the MIT Institute for Data, Systems, and Society and Media Lab Human Dynamics Group, working on the intersection of urban resilience, computational social science, and big data analytics. I'm also a Data Science Consultant for the Global Facility for Disaster Reduction & Recovery (GFDRR) and Transport Global Practice at The World Bank, working on big mobility data analytics for urban development, disaster risk management, and transportation modeling.   
I obtained my Ph.D. from Purdue University, advised by Dr. Satish V. Ukkusuri and Dr. Seungyoon Lee. Prior to that, I obtained my Masters and Bachelor Degrees from the University of Tokyo, advised by Dr. Yoshihide Sekimoto.

My research interests including urban disaster resilience modeling, geospatial big data analytics and geospatial-AI, and using these techniques for urban policy applications.  
 
Apart from research, I love playing soccer (you can watch my screamer freekick here), enjoy cooking seafood dishes (my spécialité is acqua pazza), and eating ramen whenever I have the chance.
