Self-introduction
My research interests are in particle physics and physics education research. (1) Numerical calculations of quark-gluon-plasma on finite temperature lattice QCD (2) Physics education research for active learning My hobbies are driving, coffee, and classical music. I am a loving wife and a loving daughter.
