主讲人简介:

Tong Ping is an assistant professor jointly at Division of Mathematical Sciences and Asian School of the Environment, Nanyang Technological University (NTU), Singapore. He has a Ph.D. in computational mathematics from Tsinghua University. Before joining NTU in September 2016, he was a postdoctoral fellow at University of Toronto and Stanford University successively for a total of four years. His research is primarily focused on inverse problems, numerical modeling, and seismic imaging of the Earth’s interior.

主讲内容:

Mathematical inverse problems have wide applications in geophysics, medical imaging, nondestructive testing, signal processing, computer vision, machine learning and many other fields. Solving an inverse problem in mathematics is the process of calculating the causal factors (parameters) from a set of observations (data).  In this talk I will first briefly talk about the theories of inverse problems for partial differential equations. This part provides us the fundamental tools to solve realistic problems in geophysics, such as estimating velocity structure of the Earth’s interior, determining earthquake locations, and mapping subsurface boundary topography. The application of the inverse problem theories into these practical problems will then be presented. After that, we will discuss the importance of solving inverse problems in modern oil & gas industry, as well as in achieving a better understanding of earthquake occurrences, distributions, and associated geologic hazards.
