Andrew's primary research interests include species' use of highly transformed habitats, conservation management in human dominated landscapes and habitat restoration. He is particularly interested in the impact of invasive species on native community assembly and function. Recent work has included quantifying novel ecosystem support of native species, invasive species distribution mapping, and resource use by native species in human-modified habitats.

His current PhD research, supervised by Assoc Prof Salit Kark , explores why certain certain species do well in human dominated habitats, and how introduced species impact native community interactions. To answer these questions, Andrew is examining how the presence of the non-native Common Mynah and the native Noisy Miner affect bird communities in South-west Australia. The outcomes of this work will help to inform conservation policy for native species as well as management plans for invasive species.
