Research Summary

I study the causes and consequences of individual differences in cognition and behaviour in wild birds. I employ a mixture of field-based research using advanced automated data collection devices, cognitive assays in captivity and molecular techniques. My current research aims are to identify causal directions of host-microbiome relationships in wild animals, provide novel insight into environmental determinants of individual differences in microbiome, identify mechanisms underlying microbiome-mediated cognition, and examine trade-offs and fitness consequences associated with host-microbiome interactions. To date I have used 16S rRNA sequencing and bioinformatics with QIIME 2 to categorise the wild gut microbiome in birds.

Inferring causality will be key to understanding the microbiome’s role in driving behavioural and cognitive variation. I am interested in metagenomic and metabolomic approaches as a means to look for molecular markers that indicate microbiome-mediated neurological processes
