My research interests can be broadly described as analysis of partial differential equations and spectral analysis, as well as alternative theories of gravity, which was the theme of my PhD thesis New Vacuum Solutions for
Quadratic Metric-affine Gravity.

My current research deals with the massless Dirac operator primarily.
