Overview
Profile summary
I am a Lecturer in Marine Sciences (Coastal Processes) focusing on understanding the multi-scale coastal dynamics and hazards through field measurements and numerical simulations of ocean currents, wind-waves and sediment transport. My latest project, SPLASH, develop a digital prototype for forecasting wave overtopping using AI and EO (see https://coastalmonitoring.org/ccoresources/SPLASHDT/). Before taking on my current role, I was previously working as a senior wave scientist at the Ocean Forecasting R&D group of the UK Met Office, studying the air-sea boundary layer dynamics and contributing to develop novel coupling strategies between atmosphere, waves and ocean global and regional models. I was part of the WAVEWATCH III code developer group and I was the co-chair of the Surface Waves Activity Group in the UK National Partnership for Ocean Prediction.
As a member of the Coastal Processes Research Group and the C-COPE research centre, I help designing and conducting monitoring programs, field deployments, and numerical modeling of coastal hydrodynamics and sediment transport. I also teach several ocean modules and support and advise graduate and undergraduate students.
I completed a B.Sc. in Marine Sciences (five-year degree in physical oceanography) at the University of Vigo, Spain. I hold a M.Sc. degree in Integrated Coastal Zone Management and Engineering (Hydraulic Institute of Cantabria; University of Cantabria, Spain) and a Ph.D. in Coastal Processes (University of Plymouth, UK). My Ph.D. studied those linkages between the upper shoreface and the inner continental shelf during storm conditions and major implications in the subsequent beach recovery. The study combined morphological observations, in-situ measurements of waves and currents, and numerical simulations of sediment transport (using Delft3D-WAVE and Delft3D-FLOW).
Roles on external bodies
- Co-chair of the SurfaceWaves Activity Group (SWAG) for the UK National Partnership for Ocean Prediction (NPOP). NPOP comprises the Met Office, Plymouth Marine Laboratory (PML), the Centre for Environment, Fisheries and Aquaculture Science (CEFAS) and the National Oceanography Centre (NOC). SWAG brings together UK expertise on observations, modelling and forecasting of ocean surface waves.
