Overview
My research interests lie in understanding how marine invertebrates adapt and survive in a changing and increasingly polluted marine environment, and the potential impacts of environmental change on their physiology and reproduction. My current research focuses on 2 main areas; 1) biological impacts of microplastics on marine invertebrates 2) the interactions between chronic pollution and ocean acidification on fitness and function in adult and larval marine invertebrates. In 2010 and 2011 I was part of the Catlin Arctic Survey expedition to study ocean acidification in the high Arctic. I have also led research expeditions to determine the extent of marine microplastic pollution in a number of remote locations including the Galapagos and the Azores.
In addition to my research I’m very active in public and educational outreach, teaming up with an educational charity to get my research findings fed into UK and international schools. I was short-listed for a 2014 WISE award for this outreach work which has reached >3.5 million children worldwide. I regularly contribute to policy consultations, was a witness at the 2017 Commons Select Committee enquiry on ocean acidification and regulalrly advise the BBC on marine or plastics focussed porgrammes.

Research interests
My over-riding research interests lie in understanding how marine invertebrates adapt and survive in a changing and increasingly polluted marine environment, and the potential impacts of environmental change on their reproduction, larval ecology and life history evolution. My current research focuses on 2 main areas; 1) the interactions between chronic pollution and ocean acidification on fitness parameters in adult and larval marine invertebrates; 2) the potential for environmental disruption of sperm function in broadcast spawning invertebrates and its ecological consequences. I am also a key member of an international team of biologists and oceanographers conducting ocean acidification research in the Canadian High Arctic as part of the Catlin Arctic Survey, joining their expeditions in 2010 and 2011.
Research projects
NERC UK Ocean Acidification Research Programme
I am part of a consortium involving researchers from Exeter, Plymouth Marine Laboratories, Swansea University and Strathclyde University working towards on ocean acidification effects on commercially important species for the UK-OARP. This project aims to improve our understanding of the potential population, community and ecosystem impacts of ocean acidification for all life stages for commercially important species and their capacity to resist and adapt.

Previous research
NERC Fellowship: Broadcast spawning into a changing marine environment: are sperm the weak link in a marine invertebrate’s life cycle?
My current research focuses on the susceptibility of marine invertebrate sperm to environmental disruption. Sperm are generally thought to lack anti-oxidant defence and DNA repair enzymes which potentially makes them highly susceptibility to environmental damage. My work aims to determine the impacts of ocean acidification and increasing pollution on sperm functioning and fertilization processes and to determine the consequences of any loss of function on fertilization dynamics and subsequent offspring fitness in free spawning marine invertebrates.
Catlin Arctic Survey
I am a key member of an international team of biologists, oceanographers and climate scientists conducting climate change research in the Canadian High Arctic as part of the Catlin Arctic Survey. My role in these expeditions is to study the composition of the zooplankton under the ice, relating this to the carbon chemistry and nutrients in the Arctic seawater during the winter-spring transition period, and to conduct ocean acidification experiments to determine how vulnerable these zooplankton species are to the IPCC predicted changes in this ocean chemistry.

External Engagement and Impact
Awards/Honorary fellowships
I have teamed up with the educational charity Digital Explorer www.digitalexplorer.com to produce a multi-media schools’ educational resource package 'Frozen Oceans', based on my research in the Arctic with the Catlin Arctic Survey. The resulting free educational resources are currently being used in over 13% of UK secondary schools and 1000 schools internationally.
These educational resources were a finalist for the national Education Resource Awards 2012 in the Best Secondary Resource with ICT category. My work with Digital explorer is currently being used by RCUK as a case study to best practise in pathways to impact. I also regularly give talks to the general public about this research e.g. at the Royal Geographical Society and on the summer festival circuit.
