  • Analysis of river zoobenthos communities (collaboration with London University)
  • Community ecology of coral and mangrove systems of South East Asia (Indonesia, Thailand) and South Amrica (hermatypic and soft corals, echinoderms, sponges, fish, mangrove plants and associated insects)
  • Deep sea hydrothermal and non-hydrothermal communities (echinoderms, sponges, mollusks, tube worms, crustaceans, fish)
