Fields of interest

My research interests relate to understanding the movement of water around the world, particularly changes that affect sea-level. This very complex issue requires a huge joint effort by scientists around the world using a wide range of techniques. My contribution falls into two parts:

  • striving to improve measurement of land motion by improving the capabilities of precise GPS processing and our understanding of the errors
  • performing precise GPS processing for applications of interest and interpreting the results. Vertical movement is particularly challenging and is very important for understanding sea level change and glacial isostatic adjustment.
