Professional skills: Mathematical Models for Environmental Problems，be familiar with the big data analysis and numerical algorithms, as a teacher of "Mathematical Model" and "Matlab" in Chongqing University of Education for eight years. Computer abilities: Matlab, GMS (MODFLOW and MT3DMS), CALPUFF, WRF (Weather Research and Forecasting Model, SWAT, Fluent, and so on.Major application: (1）write the codes (about 800 lines) for the simulation of activated sludge technology used in waste-water treatment plants, ASM2d proposed by IWA for reactor and one-dimensional flux model for secondary settling tank (it is a typical application of building a system by coupling the separate components by mass conservation); (2) write the codes (about 500 lines) for the simulation of population balance model, which is widely used to describe the processes involving dynamical behaviour of population properties (it is a typical application of solving partial differential equation by discretisation techniques); (3) write the codes (about 300 lines) for neural network model, which is trained by the thousands of meteorological data and used to forecast the air quality (it is a typical application of big data analysis, especially the data auto importing and pre-processing); (4) write the codes (about 300 lines) for image analysis, including batch-importing massive images of particles, counting the pixel numbers of equivalent diameter and circumscribed circle diameter, and calculating the fractal dimension (it is also a typical application of big data analysis from massive images).
