My name is Hui Tong, a PhD student from School of Physics, Peking University. My main research topic is nuclear theory, including the interactions between nucleons and using the ab-initio nuclear many-body theory to study nuclear matter and neutron star. Now I am studying on how to extract hadron interactions from lattice QCD calculations. In the iTHEMS, I hope to learn more about theoretical, mathematical and computational sciences, this will be a great opportunity to broaden my horizons.
