  I worked as a Ph.D. researcher in the field of Scientific Computing under the supervision of Prof. Jason Frank (Promotor) and Prof. Paul Zegeling (Supervisor) at the Mathematical Institute of Utrecht University. The research focused on the design of efficient adaptive numerical methods for two-phase porous media flows.The topic of my research has been the analysis of numerical schemes for Nonlinear PDEs, with applications in porous media flow, thin film flow, mass heat transfer, and reaction-diffusion processes and Hamiltonian systems. The research contributed with several peer-reviewed scientific articles to develop fast, efficient and stable numerical methods for two-phase flow problems.Four papers are published in top journals:[1] Zhang H, Zegeling P A. Simulation of thin film flows with a moving mesh mixed finite element method, Applied Mathematics and Computation, 2018, 338: 274-289. [2] Zhang H, Zegeling P A.
