Bachelor of Physics, Doctor of Mathematics, Interested in ML
27 years ago, I was born, but Nothing Special happened :). When I was a child, I always thought about one question: is the man born for a better life or happiness is just the privilege of someone. When I Traveled between Shanghai and my hometown, there are too many differences: the buildings, the lifestyle, almost everything except the human being itself. I start to care about the poor who lose the abilities to experience the beautiful world, and I am curious about what humanity will be. What is the next technology which can change the world and what the world will be? These feelings come with me along with my whole childhood and become more and more severe with time past. Thus, I studied very hard and won many first places in primary school, high school, and college.
I learned physics in college and felt that mathematics could enrich my knowledge and make me more prepared to fetch the answers. Thus I study for a doctor's degree in mathematics. Nowadays, when machine learning appears in my world, what I am inspired is the potential opportunity of human-powered by artificial intelligence through machine learning and other technologies. Maybe that will give me the answer which I am looking for. In the history of humans, each civilization's evolution comes with the development of tools. The first evolution comes when the material makes the tools sturdy, and then the fuels give them power. Can AI offer the soul to tools? I don't know, but All Roads Lead to Rome. This one may fail, but I believe there must be one left for further exploration. And I must be ready for that.

Visiting Scholar: Evolution of Nonlinear Wave Equations with TB model
CU Boulder, USA
Numerical calculation of nonlinear waves in a honeycomb structure.Analyze data structures, design numerical formats, calculate solutions for partial differential equations, and use Matlab and Python code for thousands of lines.
2018.3
Simplification of Nonlinear Wave Equations Near Dirac Point
Tsinghua University
Dynamics of nonlinear waves near the Dirac point in a two-dimensional honeycomb structure，in preparation. The existence of Dirac point in two-dimensional honeycomb structure (such as graphene) is studied. The multi-scale method is used to analyze the nonlinear wave equation in two-dimensional honeycomb structure.

Topologically Protected Edge Mode Simulation
Tsinghua University
Dynamic Analysis and Calculation of Topologically Protected Edge States in Two-Dimensional Honeycomb Structure, in preparation. Two-dimensional honeycomb structures with different optical characteristics are spliced together, and the dynamics of the simplified wave packet equation on the splicing boundary is numerically calculated. It is found that the edge state energy can maintain a certain aggregation for a long time and press the hand on the boundary. Sexual direction movement; through the WKB method in the progressive analysis, the direction of motion of the main energy of the wave packet on the boundary is the tangential direction of the boundary, and the calculation result is verified.
2018.10
Application of Machine Learning in the Determination of Flow Stability
Tsinghua University
Through the method of machine learning, the phase transition point in the physical process is identified. For example, the Kelvin–Helmholtz instability can occur when there is velocity shear in a single continuous fluid, or where there is a velocity difference across the interface. Extract the feature matrix and try to understand how the machine learning works from a physics perspective.

OdeNet for dynamic system
Tsinghua University
Extracting the patterns from the complex data is a critical problem in many areas. We replace the network in the machine learning by differential equations with multiple coefficients and optimize the parameters using machine learning methods.
