Wonjun is an expert of low temperature STM. He made Bob, which is 10 mK electron spin resonance stm of the Center for Quantum Nanoscience (QNS). His research focused on Dirac materials and high Tc superconductor. Recently he mainly focus on the symmetry based topological physics. In QNS, he focus on the development of qubit with 100% high fidelility using a optics combined stm.
"Everything should be made as simple as possible, but not simpler."
