Research Theme:

Biodiversity, evolutionary morphology and reproductive ecology of extinct and extant marine invertebrates


My research interests are early evolution, radiations and paleogeography of marine colonial invertebrates, in particular Bryozoa. I also work on their biogeography, taxonomy and reproductive ecology, and study evolution of reproductive patterns and polymorphism


Global change, biodiversity and Paratethyan faunal interchanges: a case study using bryozoans with different larval strategies

Evolution of matrotrophy and placental analogues in Bryozoa

Investment in sex in Caribbean cupuladriid bryozoans

Albian-Cenomanian Bryozoa of Japan
