I am a postdoctoral researcher at Ghent University. Previously, I was the PhD student with the joint program between Ghent University and Al-Farabi Kazakh National University.
My supervisors are Professor Michael Ruzhansky and Assoc. Professor Durvudkhan Suragan. I am interested in harmonic analysis, sub-elliptic functional inequalities, spectral geometry and PDE. My work concerns mainly in the functional inequalities on Lie groups and its applications to PDE.
