Research interests

My research focuses on the arithmetical properties of profinite fundamental groups of algebraic varieties: anabelian geometry and recently therein mainly Grothendieck's section conjecture. Along the way, I frequently use logarithmic geometry, which henceforth became an independent interest of mine. I am also interested in the number theoretic analogs.
