Ecophysiologist PDRA

I am an ecophysiologist with broad interests in animal energetics. I study how body size interacts with warming and ocean acidification to affect the ecology and physiology of marine fish and invertebrates. I use both experimental and modelling approaches.

Summary of research interests

  • >How climate warming affects the growth and metabolism of marine invertebrates and fish
  • >How body size mediates responses to climate change
  • >Metabolic scaling, how body size affects metabolic rate
  • >Respirometry
  • >Swimming kinematics and escape performance of fish
  • >R programming and modelling


Current research project

CLIMSHIFT: This project explores how climate warming affects the growth and metabolism of marine invertebrates and fish. Funded by NERC. Oct 2017 - Mar 2020
