Professor Shiu’s research program is at the interface of string theory, particle physics, and cosmology. His research aims to uncover the laws of nature at the most fundamental level, and apply the insights so obtained to understand and predict observable pheonomena in the domains of high energy physics, astroparticle and cosmology. Major thrusts of his research include developing mechanisms and models from string theory that lead to realistic four-dimensional physics, and finding observables that may teach us theories at very high energies. His research efforts have also drawn him to develop mathematical and data science methods (you can read more about his research and bio).
