I am also a postdoctoral fellow at Kazakh National University.
Previously, I was a PhD student at the Kazakh National University. My advisors were Prof. Tynysbek Kalmenov and Prof. Michael Ruzhansky. The defence of the PhD thesis was on 7 June, 2019.
I am mainly interested in subelliptic functional estimates on homogeneous stratified Lie groups.
In 2018, I was awarded the travel grant of 6th Heidelberg Laureate Forum.
