# Leo Tsukada - Assistant Research Professor

I am an Assistant Research Professor in Institute for Gravitation and the Cosmos. Before I moved to Penn State first as a post-doc, I received my Ph.D in Physics from the University of Tokyo (RESCEU). I am also a member of LIGO Scientific Collaboration and my research interest is mainly on the data analysis of the gravitational waves. In particular, I have been interested in two kinds of gravitational wave signals; the low-latency detection of the gravitational waves from compact binary coalescences and the stochastic gravitational-wave background. Please come to my webpage for more details.
