Introduction
I am an experienced Earth Data Scientist working on geohazards and their impacts on society, focusing on groundwater flooding and space weather events. I develop multidisciplinary tools and workflows for mapping, monitoring, modelling, forecasting and understanding geohazards based on ground-based and remote sensing datasets. I have expertise in analysing and interpreting large datasets using statistical methods, and numerical and physically-based modelling approaches.

Article
STIN is a new approach for recovering natural electric and magnetic fields and reduce the influence of anthropogenic noise. The proposed approach modifies the windows of the local electric and magnetic time-series that are affected by noise with time series resulted from modifying the spectra of the magnetic time-series from a neighboring site with...
Article
Vulnerability assessments of the risk posed by geomagnetically induced currents (GICs) to power transmission grids benefit from accurate knowledge of the geomagnetic field variations at each node of the grid, the Earth's geoelectrical structures beneath them, and the topology and relative resistances of the grid elements in the precise instant of a...
Article
Geomagnetically induced currents (GICs) are a well-known terrestrial space weather hazard. They occur in power transmission networks and are known to have adverse effects in both high and mid-latitude countries. Here, we study GICs in the Irish power transmission network (geomagnetic latitude 54.7–58.5∘ N) during five geomagnetic storms (06-07 Marc...

As a consequence of measuring time variations of the electric and the magnetic field, which are related to current flow and charge distribution, magnetotelluric (MT) data in two dimensional (2-D) and three dimensional (3-D) environments are not only sensitive to the geoelectrical structures below the measuring points but also to any lateral anomali...

A novel automated approach for mapping nonurban flood extents using satellite-based Sentinel-1C-band SAR data is presented and applied in the Republic of Ireland. The methodology mapped the maximum flood extent of over 25,000 detected water bodies across Ireland over a five-year period (2016–2021). Flood extents were classified using a semi-automat...

Abstract The Lorca earthquake (May 11th, 2011, Mw 5.2) stands as the most destructive one in Spain over the last 50 years, interpreted as having occurred in an intersegment zone of the strike–slip Alhama de Murcia Fault (AMF) (Eastern Betics, Spain). Magnetotelluric data were acquired along a profile to the SW of Lorca (La Torrecilla profile), to c...

The Space Weather Electromagnetic Database for Ireland (SWEMDI) was funded by the Geological Survey Ireland (GSI, www.gsi.ie) to developed a digital database with key information for the understanding and constraining of Ireland's electromagnetic (EM) properties. The database includes: 1) Raw and clean geoelectric and geomagnetic time series; 2) lo...
Article
Constructing a power network model for geomagnetically induced current (GIC) calculations requires information on the DC resistances of elements within a network. This information is often not known, and power network models are simplified as a result, with assumptions used for network element resistances. Ireland's relatively small, isolated netwo...

Conference Paper
Continent-continent collision is a fundamental tectonic process that plays a primary role in the development and evolution of continents. The Pyrenees resulted from the continental collision between the Iberian and European plates during the Alpine orogeny. This mountain range offers an unique opportunity to study orogenic processes due to the well...

Several and contradictory geodynamic models have been proposed to explain the opening of the Alboran Sea during the Oligocene - Miocene based on different geological and geophysical data, which do not allow to unequivocally distinguish between them.

New magnetotelluric (MT) data has been acquired along a N-S profile of 180 km length that cross the Pyrenean range. The new MT data are complemented with old MT data registered at the same profile 15 years ago.
