I am a Conservation Scientist with a background in Environmental Impact Assessment (EIA). The aim of my research is to improve our understanding of the distribution and impacts of alien species, and the processes that drive biological invasions. I work at the Institute of Biology at the Free University of Berlin. My research is funded by the Alexander von Humboldt Foundation.

Professional experience

2020 – present
Member, IUCN Species Survival Commission and  IUCN SSC Invasive Species Specialist Group (ISSG).

2019 – present
Humboldt Research Fellow, Institute of Biology, Free University of Berlin.
During this fellowship I aim to:
(1) identify the factors that cause global variation in the availability of impact data for alien birds (Evans T & Blackburn TM, 2019: doi:10.1007/s10530-019-02153-z);
(2) identify the factors that influence the vulnerability of native birds to the environmental impacts of alien birds;
(3) develop novel citizen science methods to further our understanding of the distribution and impacts of alien species.

2019 – present
Associate Editor, BioInvasions Records.

2019 – present
IUCN EICAT Authority.
 I am part of a small international team of invasion scientists responsible for the development and implementation of a new methodology to quantify and categorise the environmental impacts of alien species: the Environmental Impact Classification for Alien Taxa (EICAT). EICAT will be formally adopted by the IUCN in 2020: it is aimed to complete EICAT assessments for all known alien species worldwide shortly thereafter. The EICAT Authority will oversee the assessment process and publish completed assessments on the IUCN website.

2017 – 2018
Graduate Student Mentor.
Division of Biosciences, University College London.

2010 – 2011
Consents Officer, EDF Energy, London.
 Following a secondment from Royal Haskoning to EDF Energy (see below), I was employed directly by EDF Energy to manage aspects of an Ecological Impact Assessment (EcIA) for the construction of a nuclear power station in Somerset (Hinkley Point C). Responsibilities included: management of a team of ecological consultants; consultation with stakeholders (including the Environment Agency, Natural England, Somerset County Council and the local community) to determine the scope of the EcIA; technical review of all consultant inputs, including survey reports; drafting final ecology chapters for the Environmental Statement prepared to support the development application.

2007 – 2010
Environmental Scientist, Royal Haskoning, Haywards Heath.
 EIA project management for numerous environmental enhancement projects including river restoration schemes, flood alleviation schemes and water level management plans. This role included a secondment to the Environment Agency, working as a Senior Environmental Project Coordinator for the National Environmental Assessment Service (NEAS), managing EIAs undertaken for internal Environment Agency flood alleviation schemes.
