Development and validation of new data products from satellite sensors and their use in the study of mesoscale processes using a variety of sensors and techniques.

Particular interests include:

Generating altimeter products for oceanography
New products from the ESA Explorer missions SMOS (Soil Moisture and Ocean Salinity), CryoSat II and GOCE (Gravity field and steady-state Ocean Circulation Explorer)
Preparing for the new ESA missions, including the Sentinel missions
Applying new data technologies to data access tools
Use of satellite altimetry and its combination with Sea Surface Temperature, ocean colour, model data and in situ measurements

Committee and Board Memberships:

Member of the NERC Administration/Science Administration Promotion Panel

Member of the NEODAAS Advisory Committee

Chair of the NOCS Facilities Sub-Committee
