His research interests include chemical physics and statistical mechanics.
In 2001, Kawasaki was awarded the Boltzmann Medal for "his contribution to our understanding of dynamic phenomena in condensed matter systems, in particular the mode-coupling theory of fluids near criticality, and nonlinear problems, such as critical phenomena in sheared fluids and phase separations".
