Biography

Martin is responsible for the mobile and permanent broadband seismic networks operated by the Seismology Lab. He provides and manages databases, real-time data links, seismological analysis software and computing infrastructure. The main field equipment pool currently comprises 68 mobile broadband seismometers, 5 tiltmeters and 2 infrasound sensors. For more details about these instruments see here. The equipment is frequently deployed in collaboration with other research centres and Martin was involved in field projects studying Teide volcano (Canary Islands), Etna volcano (Sicily), Arenal and Turrialba volcanoes (Costa Rica), the Albertine Rift (Uganda), the Great Rift Valley (Ethiopia), Vatnajokull glacier (Iceland), Bárðarbunga volcano (Iceland) as well as microseism and earthquake activity in Ireland.  Martin also looks after the near surface geophysics equipment pool which is mainly used for undergraduate teaching. It comprises a multi-channel seismograph, a magnetometer, DC resistivity equipment and a VLF sensor.
Martin studied geophysics in Cologne, Germany graduating with a thesis on numerical modelling of atmospheric processes. He went on to do an M.Sc. in Applied Geophysics in Galway, Ireland and afterwards gained experience in near-surface geophysics while employed with geophysical consultants in Dublin. Martin then joined the Geophysics Research Group in UCD. He completed his PhD project on seismic rock fracture characterization in 2010.
