“Do something interesting and useful. Never follow others, let others follow you!” This is the research philosophy of Dr. Li which has been fully reflected in what he has done so far, in particular in the development of the new emerging field – Phononics and Thermal Metamaterials in which he has made pioneering and significant contributions, at the cross-section of thermal sciences, materials sciences, and nanotechnologies. He has made important and impactful contributions in understanding the heat transport in low dimensional systems, in particular, in clarifying the necessary and sufficient condition of Fourier law, and conceiving fundamental phononic devices like thermal diode, thermal transistor, thermal logic gates, and thermal memory. These works have laid a theoretical foundation for phononics. Most recently, his research has been extended to the thermal metamaterials. Recently he has extended his research to quantum sensors.
