I am generally interested in the structure and evolution of galaxies. As such a large part of my research focusses on the distrubution and kinematics of hydrogen in spiral galaxies. As such my research is dominated by observations of HI, neutral hydrogen line emission at radio wavelengths, and Hα, ionized hydrogen line emission at optical wavelengths. However, to understand the full flow of the gas in galaxies we also need to look at other components of spiral galaxies such as the stars, star formation and the molecular gas and therefor I always try to combine observations at several different wavelengths in my research.

With the advance of large all sky surveys it becomes important to be able to analyse most datasets in a automated manner. In the analysis of neutral hydrogen the tilted ring model is a common tool to use to retrieve the kinematical parameters. However, this process is still largely manual and subjective. I have therefore also developed an interest in, and started developing, codes that can automatically fit these models to HI data cubes
