Brian Trevelline, PhD

Nutrition is essential to life - from fundamental cellular processes to the structure of entire ecosystems. For vertebrates, host nutrition is mediated by the gut microbiome - the archaeal, bacterial, fungal and viral communities of the gastrointestinal tract. However, we have a limited understanding of how host-microbe nutritional interactions influence vertebrate ecology and evolution.
​ 

My research seeks to understand how host-microbe nutritional interactions influence wildlife health, ecology, and conservation. Specifically, I use cutting-edge approaches such as wild-derived germ-free animal models, culture-enriched microbiome profiling, and metagenomic techniques to study interactions between animal nutritional ecology, physiology, gut microbiota, and extrinsic environmental factors. ​
