Overview

Dr Gregory Paull is the founding manager and senior NACWO (Named Animal Care and Welfare Officer) of the Aquatic Resources Centre (ARC), a large interdisciplinary £12M facility which comprises of 600m2 of research and teaching space and a further 300m2 of plant/life support systems.  Greg co-led the design and implementation of the facility in 2011 and oversees a team of experienced husbandry staff to help manage this Centre. The ARC supports ~ 20 research groups and, in doing so, houses a wide range of freshwater and marine species, each relevant to a series of specific research questions that address key aspects of environmental and human health, environmental protection, and drug discovery.

In addition to his facility management and operational skills, Greg is particularly keen in promoting improved husbandry and welfare practices for laboratory-maintained fish and has a successful track record presenting at fish husbandry workshops, publications and contributing to guidelines/policies developing best practice. In 2008, he was awarded a Winston Churchill Memorial Trust Travelling Fellowship to study zebrafish (Danio rerio; the most widely used fish species in scientific research) in the wild (Bangladesh). 

Greg is currently a Co-I/supervisor on several grants, including. 

  • with Prof Charles Tyler (PhD supervisor) how to unlock the full potential of fish as scientific models by considering their welfare
  • with Prof Rod Wilson (NC3R funded) investigating the role of water chemistry in zebrafish welfare and reproducibility of research studies 
  • with Dr Matthew Witt and Dr Lucy Hawkes (NC3R funded), using highly innovative field techniques to refine the tagging of pelagic fish and sharks (most recently to deploy bluefin tuna and basking sharks off the UK coasts with senor devices to monitor post-release welfare)
  • with Dr Eduarda Santos (Environment Agency funded) researching the effects of chemical exposure on whole genome RNA transcriptomics of aquatic invertebrates

Greg previously worked at CEFAS as an RA in their fish histopathology and molecular diagnostics disease labs and studied at Queen Mary, London (BSc); Plymouth University (MSc) and University of Exeter (PhD).  

When not looking after aquatic creatures and researchers in the ARC, Greg can be found engaged in sport (challenging new Uni students at various sports) or enjoying walks/wildlife and social events.
