Systematics and phylogeny of Copepoda (Crustacea), with emphasis on the Order Cyclopoida.

Diversity of Copepoda in extreme environments: phytotelmata, anchialine systems, deep-sea meiobenthos and bathypelagic environments.

Barcoding and metabarcoding of zooplankton as a rapid assessment and monitoring tool to evaluate changes of biodiversity due to human activities.

Barcoding and metabarcoding of deep-sea meiofauna as a rapid assessment and monitoring tool to evaluate mining impacts on biodiversity.

Deep-sea population connectivity, with emphasis on epibenthic Copepoda.

Colonisation processes of phytothelmata and anchialine cave species.

Confocal Laser Scanning Microscope and µCT data as imaging tools to accelerate and/or complement the process of species descriptions.
