I am a researcher and part-time teacher in pure mathematics.

My licentiate thesis treated the maximum principle for a generalization of complex analytic functions to generic embedded Cauchy-Riemann manifolds. Title: The Maximum Principle for Cauchy-Riemann Functions and Hypocomplexity (2012).
My doctoral thesis was a continuation of my licentiate thesis, it primary subject is a subspecialty of partial differential equations, namely locally itegrable structures, and the schwerpunkt was maximum principles, hypoelliticity and uniqeness conditions for various generalizations of holomorphic functions om submanifolds. Title: Regularity and Uniqueness-related Properties of Solutions with Respect to Locally Integrable Structures (2014).

Following my dissertation my primary field or research has been the theory of polyanalytic functions and their various generalizations. I am currently also in collaboration with Per Åhag in the analysis group (that is within a specialty different from that of polyanalytic functions).
