I am a coastal and shelf sea pelagic ecologist predominantly working on the causes and consequences of jellyfish population variability and blooms events.

An understanding of the natural world is a source of not only great curiosity, but great fulfilment – Sir David Attenborough

Research interests

Specialisms: Gelatinous zooplankton, jellyfish blooms, scyphozoan life histories

I am a marine ecologist with a broad and multidisciplinary interest in coastal and shelf sea pelagic ecosystems.

My primary interest is the study of jellyfish blooms, which has involved a number of international partnerships over the last 20 years. I was a key member of the NCEAS-funded Global Jellyfish Blooms Working Group and a leading co-author, with Dr Robert Condon, of the Jellyfish Blooms Database Initiative (JeDI), the first global database of in situ jellyfish presence and abundance data. I have co-edited a book on Jellyfish Blooms and have provided interviews and popular science articles for various TV, radio and online media, as well as contribute to the BBC’s Blue Planet II series as a scientific advisor.

A primary area of my research in recent years has focused on understanding the causes and consequences of jellyfish blooms. Using a combination of field sampling of coastal and estuarine jellyfish and laboratory experiments, we explore the effects of various physico-chemical parameters on reproduction and life histories of medusae and polyps to determine what drives jellyfish population dynamics. In addition, I am interested in the impact of jellyfish blooms, both socio-economically on industries such as coastal tourism in the Mediterranean and UK, as well as on the pelagic trophic structure and function in collaboration with colleagues with expertise on biogeochemical cycling and stable isotope analyses.
