Alonso Hernández Guerra


Alonso Hernández-Guerra received the Physics diploma from the Universidad de La Laguna in 1984 and the Ph.D. degree in Physical Oceanography from the Universidad de Las Palmas de Gran Canaria in 1990. Part of his Ph.D was done in the Joint Research Centre (JRC) at Ispra (Italy), centre belonging to the European Commission. From 2003, he is full Professor at the Universidad de Las Palmas de Gran Canaria. He started his research in remote sensing applied to the study of the mesoscale patterns in the ocean. In 1999, he carried out a sabbatical year at Woods Hole Oceanographic Institution (WHOI) collaborating with Terrence M. Joyce where he was introduced in the studies of large-scale circulation of the ocean. In 2011, he spent a sabbatical year at Scripps Institution of Oceanography (SIO) collaborating with Lynne D. Talley studying the upwelling processes of the Meridional Overturning Circulation carried out in the Indian and Pacific Oceans. He has been involved in several national and European research projects and is author of more than 55 peer-review papers with an h-index of 21.
