In my PhD research, I develop novel numerical methods for the modeling of the aerosol dynamics, which can be described with the General Dynamic Equation of Aerosols (GDE). Thus far, the Finite Element Method (FEM) and its extension the Petrov-Galerkin Finite Element Method (PGFEM) has been tested for the single component GDE (Published paper I). Next step is to extend the methodology for the multicomponent GDE (MCGDE). Preliminary results are promising. Furthermore, after the accuracy and efficiency of FEM is established, it will be used in estimation of the aerosol process rates from simulated and measured data.
In addition of my research, I have also lectured the introduction course to the mathematics during two semesters (2020-2021).
