Research interests

  • Investigation of biological patterns, especially the historical role of megaleaps in seeding fast lane evolution in the invertebrates
  • The effect of environmental perturbations on invertebrate community function
  • Invertebrate-mediated processes at the water-sediment interface
  • The study of rise and collapse of biological hierarchies and their transitional interface exchanges as major determinants of sustainability
