I am a senior data scientist in the SciML group. My current research focuses on solving a variety of problems in physics using machine learning, such as data qualification and selection, parameter inference and optimisation and 3D segmentation. I am also working on improving machine learning methodologies, such as optimising variational autoencoders based on maximum entropy production and combing variational inference and adversarial learning. I was granted a PhD degree in Civil Engineering by Tsinghua University and then another PhD degree in Geophysics by the University of Oxford. Before joining SciML as a data scientist, I worked as a postdoc researcher at Yale University and the University of Oxford.
