Welcome to my personal homepage. You will find information about my junior research group "Numerical analysis of multiscale methods" on its own homepage and as associated project within the CRC 1173 "Wave phenomena" on the corresponding project page.

News

The CRC 1173 is currently seeking to recruit four doctoral researchers, one of the positions is within the assocated project "Numerical analysis of multiscale methods". More Information here, the offical announcement is here.







Research interests

  • multiscale (finite element) methods
