Sponges
The leading source of new marine compounds
Sponge natural products
Our group is investigating the chemistry and biology of possibly the earliest animals to appear on our planet: sponges (phylum Porifera).
Sponges represent today about 9,200 species, of which 161 species are found in Swedish waters and probably more than 300 species in Norwegian waters. Sponges occur worldwide, from the tropics to polar regions, from shallow waters to the abyss. In addition to being important models to understand the evolution of animals, sponges are unquestionably the leading source of new marine compounds, with 200 new sponge metabolites discovered each year.
Using various sources of data such as secondary metabolites, morphology and genetics/genomics, our lab studies the evolution of these animals and aims at discovering sponge natural products, to understand why and how they are produced, and if that could lead to new drugs.

January 2020. We are hosting Julio A. Díaz, a PhD student from the University of the Balearic Islands, to work on deep-sea sponges.
The 11th World Sponge Conference will be held in Bali, Indonesia in 2021.
