Lynsey Harper, PhD

Hi there! I am a postdoctoral researcher in the Mariani Lab working on the SpongeDNA project. Marine sponges are natural filters that trap particles in their tissues, including DNA released by animals into the water column (i.e. environmental DNA, eDNA). Using aquaria and field experiments, I will develop and optimise DNA metabarcoding of sponge tissue (i.e. natural sampler DNA, nsDNA). I will compare novel nsDNA metabarcoding with aqueous eDNA metabarcoding, and evaluate the potential applications and limitations of this approach for marine biodiversity assessment.


I hold a PhD in Biological Sciences from the University of Hull, UK; an MSc in Quantitative Methods in Biodiversity, Conservation & Epidemiology from the University of Glasgow, UK; and a BSc (Hons) in Zoology from the University of Glasgow, UK. Prior to joining the Mariani Lab, I held postdoctoral positions in the EvoHull group at the University of Hull, UK, and at the Illinois Natural History Survey, University of Illinois at Urbana-Champaign, USA.


I am an aquatic ecologist with a strong interest in both freshwater and marine ecosystems, community ecology, and the development of new tools for biodiversity monitoring. I am excited to be involved in the innovative and fast-paced field of eDNA metabarcoding. I believe this tool has enormous potential for biodiversity monitoring in aquatic environments to map multi-species distribution, estimate multi-species occupancy, reveal species associations, construct ecological networks, and improve biomonitoring. I am keen to advance eDNA metabarcoding in terms of methodological development, standardisation, and application to ecological questions in order to better inform biodiversity conservation, management and policy. Sponge nsDNA metabarcoding could be the next piece of this puzzle and bypass the issues encountered with aqueous eDNA capture in marine environments, including small water volumes, dilution effects, time-consuming filtration and plastic waste, and resource-intensive automated underwater vehicles.
