I am broadly interested in the diversity, systematics and ecology of ctenophores and medusozoan cnidarians. My recent work focuses on integrative morphological and molecular taxonomy of these groups, including reference libraries of DNA barcodes. My research also includes descriptive studies on faunistics and spatial and temporal distributions of gelatinous zooplankton based on both physical sampling, optical methods and, more recently, eDNA, as well as experimental work on their ecological and trophic roles in the pelagic.

I am a member of ICES Working Groups on Integrated Morphological and Molecular Taxonomy (WGIMT) and Zooplankton Ecology (WGZE), SCOR working group #157 and UN Ocean Decade Action No. 102.2 MetaZooGene, and The Hydrozoan Society
