I am a biologging scientist with a diverse interest in animal behaviour in the wild. My research has concentrated so far on cooperative breeding in meerkats and mole-rats, bird migration, and anthropogenic effects on wildlife behaviour. Using data-loggers, I aim to uncover behavioural patterns in small vertebrates and understand them in relation to social, anthropogenic and climatic factors. I am also interested in developing methods of recording and analysing body-acceleration data and translating them to behavioral models

Specific research interests:

• Cooperative Behavior
• Movement ecology 
• Underground Behavior 
• Bird migration 
• Citizen Science
