I have a BSc in Marine Biology and Polluted Ecosystems from the University of Portsmouth (graduated 2005) and an MSc in Freshwater and Coastal Sciences from the University College London (graduated 2007). Following my MSc, I worked at the Zoological Society of London where for 3 years I coordinated species extinction risk assessments of freshwater species using the IUCN Red List categories and criteria. These assessments formed part of a wider project called the Sampled Red List Index project which aims to create a less biased global biodiversity indicator through the coverage of a larger number of the more diverse, less charismatic species groups (i.e. invertebrates). It was my research on extinction risk data gaps that led me to create a PhD, in collaboration with the Zoological Society of London, Bangor University and the University of St Andrews, on methods for addressing knowledge gaps on the poorly-known Ganges River dolphin. During my PhD I was awarded a NERC fellowship within the Parliamentary Office of Science and Technology where I spent 3 months learning about the policy-making process; writing a policy brief on the environmental impacts of tidal barrages; and, working on the Severn Barrage public enquiry. Since my PhD and prior to my current postdoc position here at UCL, I worked as a consultant writing papers for the International Institute for the Environment and Development (IIED) and the International Whaling Commission.

For my PhD research I explored the uses of local informant data for studying the poorly-known Ganges River dolphin in Bangladesh, as well producing an up-to-date population estimate using a capture-recapture analysis. During my research I developed an interest in the use of citizens as local environment monitors and established a small community monitoring group to collect data on dolphin mortalities. As of April 2018, I have been working on the European H2020-funded Doing It Together Science (DITOS) project, a project involving 11 European partners which aims to increase European engagement with citizen science.

My research interests include: addressing global biodiversity gaps; citizen science as a tool for addressing human-wildlife conflict and environmental data deficiencies; optimising ethics procedures in participatory research; and science communication.
