Dr Pennie Lindeque is a senior scientist with more than 18 years expertise in the area of development, systematics and trophic interactions of eukaryotes, in particular zooplankton. Current focus includes investigating the bioavailability and impact of microplastics on marine biota combining laboratory experiments and field sampling. As a molecular biologist her research has also centred on using molecular techniques to help answer ecological questions; including developing molecular techniques for identification of holoplankton and meroplankton, including Next Generation Sequencing technologies, and investigating trophic interactions through molecular gut content analysis.

Pennie has published 34 peer reviewed papers with more than 1600 citations (h-index 17). She has led a number of field campaigns, most recently looking at the abundance and distribution of microplastics in coastal and open ocean areas. She has supervised a number of MSc and MRes students plus 8 PhD students (4 to completion and 4 current) with academic links to University of Plymouth, University of Exeter, University of Swansea, Queen Mary University of London and Stazione Zoological, Naples (Open University).
