David took up the post of centre ecologist at the end of summer 2013 following a period in environmental consultancy. He is an applied ecologist whose main interests involve the conservation of mammals in Ireland and Indonesia.  His PhD focused on factors that affect the exposure of mammals and predatory birds to anticoagulant rodenticides and these influence the exposure of non-target animals to these highly toxic and persistant compounds.  

He is also interested in understanding and resolving human wildlife conflicts between Sulawesi's human population and its unique mammals and birds.   He is particularly keen on understanding the imapct of egg harvesting on the endemic megapode, the Maleo (Macrocephalon maleo) in the understudied southeast of this biodiversity hotspot. He also has a similar interest in the endemic dwarf buffallo, the Anoa (Bubalus spp) and has recently completed a study investigating reasons for hunting of this species on Sualwesi. 

His main responsibilities within Quercus involve supporting the Quercus manager in the day-to-day management and running of the projects undertaken by Quercus.
Research Interests 

  • Ecotoxicology of anticoagulant rodenticides in predatory mammals and birds
  • Application of methods for studying mammals
  • Impact of invasive mammals on naive communities;  particularly rodents and shrews
  • Human wildlife conflicts of Sulawesi's endemic avian and mammal fauna
