Dr Michael Chadwick is an aquatic biologist interested in exploring both applied and basic ecological questions. His work focuses on understanding how ecosystem structure and function, specifically related to macroinvertebrates, respond to changes in environmental conditions. 

He earned a BSc in Environmental Science at Cook College, Rutgers University. While at Rutgers University, he was employed by the United States Environmental Protection Agency to monitor streams, lakes, and estuaries in the Northeastern United States.

He has an MS in Zoology (Auburn University) and a PhD in Ecology and Environmental Science (University of Maine). He has also worked as a postdoctoral researcher at the University of Alabama and the University of Plymouth.


  • Effects of natural and human-induced ecosystem changes on aquatic organisms
  • Implications of ecosystem changes on the functioning of aquatic ecosystems

Michael's main research goal is to pursue the general questions: 'What are the effects of natural and human-induced ecosystem change on aquatic organisms, and what are the implications of these changes on the functioning of ecosystems?'

His past research has spanned large spatial scales in varied aquatic systems. This includes work on the main channel of the Mobile River (Alabama), tidally-influenced rivers in England, tributaries of the St. Johns River (Florida), and intermittent streams (Maine and Florida). These studies have focused on understanding how invertebrate function and/or structure are affected by changes in both the biotic and abiotic environment. 

Current projects focus on several topics such as London’s urban rivers, biodiversity offsetting, freshwater fish conservation in India, and macroinvertebrate community structure in Brunei. In each of these studies, he is researching the interplay between biotic factors (eg competition, predation, food quantity and quality, nutrient cycling) and abiotic factors (eg water quality and quantity, habitat availability, climatic variation), which can alter life histories, community composition and ecosystem function.




PhD supervision

Michael is interested in receiving enquiries from potential PhD students on: 

  • Ecology of tidally-influenced aquatic systems 
  • Large river ecology (especially the Thames) 
  • Spatial arrangement of habitats and reaches in aquatic ecosystems 
  • Catchment-scale drivers of ecosystem function 
  • Intermittent systems 
  • Life histories of aquatic organisms
