Liz Humphreys

Job Description

Senior Research Ecologist

Role

Liz's current job is to develop research projects principally concerned with wetland and marine issues. Her most recent work has focused on understanding the impacts of the renewable industry on seabirds. Previously to joining the BTO, Liz's main research interests involved quantifying the factors that determine the foraging performance and energetics of seabirds.

Qualifications

BSc (Hons) Environmental Biology, University of St Andrews, 1991-1995 MSc Ecology, University of Aberdeen, 1997-1998. PhD Kittiwake Foraging and Energetics, University of Stirling, 1998-2002.

Interests & Responsibilities

As well as her commitments to the Wetland & Marine team within the BTO, Liz also worked on a diverse range of topics including machair, urban and woodland ecology. She has also worked on a number of policy relevant projects including the management of goose management populations in Scotland.
