**Research Interests**

My research interests belong to the area of mathematics known as global analysis. More specifically, I use analytical tools in the study of shape. Since 1995 I have been almost exclusively interested in the geometric and topologic applications of the Seiberg-Witten equations, a system of nonlinear elliptic equations arising in quantum field theory which turned out to be extremely versatile in detecting subtle properties of 3- and 4-dimensional spaces.
