Research Field :
Deep Learning for Modelling and Simulations in Physics 

Research Summary :
Datadriven modeling methods, especially those based on deep learning, have attracted much attention in recent years.
Wellknown models that combine deep learning and physics include Hamiltonian neural networks and Physics Informed Neural Networks.
My research combines deep learning and geometric mechanics theory to construct models that preserve physical properties and to analyze these properties theoretically.
At the same time, I aim to reduce errors and improve the accuracy of physical simulations by simplifying more complex deep physical models.
