APCOM-ACCM Student Presentation Award
This award is presented to students delivering outstanding presentations at APCOM-ACCM.
About awarded research
This research explores the possibilities to use macroscopic diffusion equations to accelerate the convergence of conventional iterative schemes when solving the relaxation-type gas-kinetic equations under the framework of discrete velocity method.

Your impression & future plan
I feel surprised and honored to be presented this award. The search for efficient numerical methods in an ongoing quest. I would like to keep exploring the possibilities and extend by proposed methods to a broader range of problems.
