My research mainly focuses on the analysis non-smooth problems from fluid mechanics. I am particularly interested in operator theoretic properties as generator properties of analytic semigroups as well as maximal regularity properties in different non-smooth situations.

Here is a list of my publications followed by a list of recent preprint:
