Writtle University College and ARU have merged. Writtle’s full range of college, degree, postgraduate and short courses will still be delivered on the Writtle campus. See our guide to finding Writtle information on this site.

Dr Paty Celis

Faculty of Science and Engineering
Life Sciences
Areas of Expertise:
Animal and environmental biology

Paty’s research expertise is in evolutionary biology with a particular focus on behavioural and molecular ecology.

[email protected]


Paty is interested in the development and application of molecular tools for answering ecological and evolutionary questions. She has used molecular tools to study breeding behaviours (eg investigating breeding tactics: monogamy, polyandry, polygyny, parasitism, etc) and to determine the evolutionary history of hybridising species (population genetics).

Paty has also been involved in research projects concerning physiological adaptations in response to environmental changes.

Research interests

Paty is a member of our Applied Ecology Research Group and Behavioural Ecology Research Group.
