Dr Candice Ann Owen

Lecturer in Entomology

PhD, Entomology, Rhodes University (2016)

Candice completed her PhD at Rhodes University in 2016. She followed it with two years as a postdoctoral fellow looking at the link between thermal tolerance and respiratory rates in insects. In 2018, Candice took up a position as an entomology lecturer in the Department of Zoology and Entomology teaching courses on cell biology, insect form and function, plant-insect interactions and global climate change, while also supervising student projects. Her main research body looks at the interaction between thermal physiology and metabolism, and the adaptability thereof. Candice hopes that by exploring the link between the two, and how they change with eachother, she can show how climate change could be expected to affect insects in the future. 

Research interests

  • Insect thermal physiology
  • Insect metabolism
  • Climate change
