Trained in biology and oceanography, Guillem started his scientific career in the study of deep-sea benthic ecology by means of remoted operated vehicles (ROVs), mainly focused on how environmental variables and seafloor parameters determine species distribution. With time his interest in benthic species capable of creating habitats grew and thus, he started to look at the effect that structuring species can have on the diversity of the surrounding fauna.
During the Ph.D. his research became more specific and multidisciplinary, as he focused on the study of reef-building cold-water corals. The main aim of Guillem’s research is to reveal what are the main environmental drivers and paleo-climatic events that control cold-water coral reef and mound formation since the Late Quaternary. In this context, a wide range of methods are used to investigate both the present-day processes and paleo-evolution of these bioconstructions. These include the analysis of ROV video-transects, aquaria experiments and the analysis of coral mound deposits by means of Uranium series, geochemical proxies and computed tomography.
