Areas of interest
- Observing global seasonal, transient and secular deformation caused by
surface mass transfer linked to the global water cycle.
- Self-consistency and mass conservation in global
loading models and the water cycle.
- Direct measurement of ocean tide loading (OTL) and solid
Earth tides
using GPS.
- Monitoring plate tectonic deformation on a
global scale using observations of Global Positioning System
satellites, and
analysis of plate boundary deformation especially in Greece, Italy and the eastern Mediterranean.
- Geodetic studies of deformation which occurred
during recent large individual earthquakes, especially in Greece
and Turkey,
using GPS, triangulation and also
Synthetic Aperture
Radar (SAR) interferometry (InSAR).
- Inverse methodology for earthquake source
parameter estimation from geodetic data, and formation of a realistic
error
budget in this process.
- Estimating the rheological properties of the
lower and upper crust from geodetic (GPS and InSAR) measurements of
post-seismic deformation following large earthquakes, especially in Greece.
- Measuring tropospheric water vapour with GPS ("GPS
meteorology").
- Applying GPS meteorology observations to the
problem of tropospheric microwave delay which affects InSAR
measurements.
- Monitoring of offshore platform subsidence
during oil and gas extraction.
- Use of low-cost GPS receivers to monitor engineering
structures, coastal
and mining-related deformation, and to determine vehicle position and
attitude.
Collaboration
I collaborate with a wide
variety of geodesists, solid-Earth geophysicists, cryospheric
scientists, meteorologists and others. If you have an idea for a
joint project or a research visit to our group, I'd be very happy to
hear from you.
