Our Group

We share our interest in various aspects of venom research, ranging from venom discovery, evolution, phylogenetics, biochemistry, pharmacology, chemistry, and therapeutic application. We come from diverse scientific backgrounds and develop and implement research ideas both individually and together. In addition to being dedicated scientists, we care about the motivation, success, and well-being of team members and ensure a safe, positive, and inclusive environment where scientific problems and ideas can be openly shared, and where we learn from each other, regardless of background and academic rank.

The Cone Snail

Treasured object of our research

Bio: Relatively young genus (oldest fossil: 55 million years); highly diverse (700-800 extant species); predation on polychaete worms was the ancestral state and the majority of living snails prey on worms. Snail and fish-hunting clades evolved later with the major radiation of fish-hunting cone snails during the Miocene, 15-10 mya.

Selected Skills: High-throughput peptide mutagenesis, biosynthesis and delivery

Passion: Enjoys the warm weather of the tropics with the greatest diversity found in the Indo-Pacific region, uses highly efficient venom delivery system to envenomate prey with a complex mixture of peptides (conopeptides or conotoxins).
