Research interests

I am an interdisciplinary conservation ecologist working at the interface between the environment and society. My research seeks to understand the impacts and management of man-made global change on ecosystems, and human-environment interrelationships. I have published research on the impacts and management of a variety of global change issues - most notably Artificial Light at Night (ALAN). ALAN is a recently emergent and rapidly growing focus for global change research in the 21st century with ramifications for ecosystems, human health, and human-environment interrelationships.

I am Principal Investigator of the NERC funded ‘Artificial Light Impacts on Coastal Ecosystems (ALICE)’ project, which combines expertise from the UK's leading marine science institutions to tackle fundamental gaps in our understanding of coastal ecosystem responses to ALAN, and how we can manage them.

I have research expertise in marine and terrestrial ecology, the ecology of the night time, photobiology, sensory pollution,  community ecology, urban ecology, remote sensing and Geographical Information Systems, culturomics and conservation.
