Research interests

Research interests

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.

Applications

My main current project is working with Antarctic GPS data to produce vertical rates and assess their errors as part of the RATES and REGINA projects.  I am working with two international teams headed by Jonathan Bamber (Bristol) and Ingo Sasgen (GFZ).

Processing improvements

Interests include:

  • non-ideal timeseries (campaign data, metadata)
  • higher order ionospheric effects on GPS
