Research Members

Professor Anne Robertson
I work on hyporheic zone ecology, groundwater ecology, colonisation and succession of microcrustacean communities in new streams, and population dynamics of lotic meiofauna.

Professor Claire Ozanne
I work on the ecology of insects and other arthropods (springtails etc) in habitats influenced by human activities. I focus on examining hypotheses about animal community assembly rules and understanding how community varies under different internal and external pressures.

Dr Lewis Halsey
My primary research investigates animal adaptations that enhance energetic efficiency. I typically study situations where food resources are scarce or energetically demanding to obtain. To help investigate these topics I am at the vanguard of the development and application of the 'acceleration technique' for estimating metabolic rate in both invertebrates and vertebrates, including humans.

Dr Alan McElligott
Our research focuses on understanding how evolution, ecology and domestication have shaped the social behaviour, cognition and vocal communication of livestock. The current main model species for our research are goats, cattle and poultry. We produce knowledge that is relevant to animal behaviour, behavioural ecology, as well as animal husbandry and welfare. We are also currently studying how public attitudes to animal welfare and sentience are formed.​

Dr Peter Shaw
My major research interest is the ecology of UK Collembola (springtails). I also examine the colonisation patterns in, and conservation management of, industrial wastes.

Dr Antonia Ford
I am interested in patterns of biodiversity and evolutionary processes generating and maintaining diversity. My current research focuses on the genomics of speciation and hybridisation in wild populations of fish species in East Africa. I mainly work on species important in fisheries and aquaculture, including endemic native species threatened by introduced invasive species. Current projects include surveying and population genetics of native species, and the development of a smartphone app for in-field species identification and distribution mapping.

Dr Harry Marshall
I am a behavioural and evolutionary ecologist. I am interested in understanding the ecology and evolution of social animals, and using this knowledge to inform their conservation and management. In particular, I work on wild social vertebrate species asking questions such as how social foraging behaviour varies with environmental conditions, and how early-life experiences influence individual behaviour, health and survival in later-life.

Dr Daniel Perkins
I am an aquatic ecologist with a focus on theoretical ecology. I am particularly interested in food webs and how metabolism changes in a warming world.

Dr Andrea Perna
My main research interests are in the areas of self-organization in biological systems, collective animal behaviour and collective intelligence in group-living animals. I focus in particular on problems of coordination of collective motion in animal groups (such as flocking and schooling phenomena) and in the collective formation of spatial structures (e.g. nest building in social insects).

Dr Julia Reiss
I research the ecology of aquatic fauna with a particular focus on energy flow within freshwater assemblages. My other research topics include biodiversity and ecosystem functioning (BE-F) and the size structure of natural communities.

Dr Isabel Santos Magalhaes
My research aims at understanding the evolutionary processes that promote and constrain organismal diversification, especially in the context of changing and dynamic environments. I am also interested in identifying whether (and what) areas of the genome have undergone episodes of strong selection leading to the observed divergence, and then to pinpoint the environmental causes of such divergence. I focus on the use of fish systems for addressing evolutionary questions. In order to address these questions my research integrates data from multiple sources combining ecological data sets such as abiotic environmental variables collected in the field and morphological, diet and stable isotope analyses of wild populations with phylogeographic, population genetic and genomic data obtained through conventional genetics and next-generation sequencing (NGS) techniques.​

Postdoctoral Researchers/Research Assistants

Dr Louise Soanes - Leverhulme Trust Early Career Research Fellow
My research focuses on the foraging behaviour and ecology of seabirds, with a current focus on examining the asynchronous breeding habits of tropical seabirds. My field sites include the Caribbean UK Overseas Territories of Anguilla and the British Virgin Islands where I am also involved in projects related to the conservation of critically endangered sea turtles and a recovery programme for the endangered Lesser Antillean Iguana

Dr Jessica Bryant
I am interested in understanding the ecology and behaviour of animals to guide threatened species conservation and management, appreciate human-ecosystem relationships, and inform public health issues. I concentrate largely on evidence-based conservation of species of extreme rarity – Critically Endangered species reduced to single, tiny, geographically-restricted populations. My current post-doctoral fellowship focuses on investigating olive baboon ecology in Ethiopia to assess their role as a possible transmission pathway in the spread of the parasitic nematode Guinea worm.

Ignacio Peralta-Maraver

My research focuses on the biology and ecology of aquatic communities of stream and rivers. Currently I am studying the link between species richness, abundance, trophic relationship, metabolic activity and secondary production of the protozoan and invertebrate communities, and their relationship with the biogeochemical conditions, flow-paths and pollutants in the hyporheic zone of lotic ecosystems.

Current Research Students

Christle Coxon (Supervisors: Dr Leigh Gibson, Dr Lewis Halsey)

I am studying the biological, physiological and psychological factors that cause overeating. I have conducted several studies investigating how foods combining high levels of sugar and fat influences appetite and eating behaviour, and whether some individuals (personality traits) are more susceptible to these appetizing combinations. I have also studied how dietary protein intake may influence appetite and food intake (Protein Leverage Hypothesis), and whether regular physical activity and body composition influence these responses.

Marie-Claire Danner (Supervisors: Dr Julia Reiss, Professor Anne Robertson)
My research interests are focused on freshwater ecology and ecotoxicology and I am interested in looking at the effects of anthropogenic stressors on freshwater ecosystems. I started my PhD in September 2015 I aim to quantify the impact of antibiotics and temperature on freshwater communities.

Tessa van Walsum (Supervisors: Dr Lewis Halsey, Dr Andrea Perna)
I study diving physiology (i.e. heart rate, body temperature, and movement) of king penguins on the French sub-Antarctic island Crozet (Ile de la Possession). During my studies I will try to answer not only how they dive so deeply, but what limitations they face when diving to such depth. My research interests include; phylogeny, diving physiology, hydrodynamics, and extend to; behaviour, personality, and sleep.

Kelly Edwards (Supervisors: Dr Lewis Halsey, Dr Andrea Perna).

Kelly is studying the flight and foraging behaviour of birds, and how differences between individuals might relate to phenotypic traits such as morphology and personality. Data is being collected on both trained birds flying short distances (The Hawk Conservancy Trust, Hampshire, UK(, and wild birds during their breeding season (Anguilla, British West Indies).

Zerihun Kebewe (Supervisors: Dr Peter Shaw, Professor Claire Ozanne, Professor Garry Marvin)

Zerihun is working in the Ethiopian highlands, studying the biodiversity of endemic coffee forests under contrasting management regimes.  He is also interviewing forest users and managers to develop an ethnographic understanding of their relationship with the forests.  The aim is to explore the extent to which local people's attitudes affect forest biodiversity, providing evidence that will underpin conservation planning.

Alumni

Dr Nick Payne

Nick undertook a Cascade Postdoctoral Research Fellowhip at Roehampton. 
His interests centre on learning how marine animals interact with their environment by studying their movement patterns, biogeographies and energetics. His Cascade Fellowship focused on a range of large oceanic species, in particular ocean sunfish in the Mediterranean and around Ireland, and tiger sharks in Hawaii and northern Australia.  Nick is currently Assistant Professor at Trinity College, Dublin

Dr Stephanie Bird (Supervisors: Dr Peter Shaw, Professor Claire Ozanne, Dr Andrew Salisbury)
Stephanie's PhD was co-funded by the Royal Horticultural Society. She studied the influence of garden planting choices on soil biodiversity and functioning. She used the Plants For Bugs experimental plots in Wisley Gardens as well as wild habitats nearby, and combined classical taxonomy with genetic barcoding to identify soil faunal biodiversity. She used a variety of approaches to quantify decomposer activity within the soils, to see whether soil function is affected by changes in its animal community.  Steph is currently employed at RHS Wisley.

Dr Damiano Weitowitz (Supervisors: Professor Anne Robertson, Dr Julia Reiss, Dr Louise Maurice and Dr John Bloomfield).

Damiano's PhD was co-funded by the British Geological Survey. He examined how geology shapes the distributions of groundwater animals across different spatial scales. He also studied the trophic effects of stygobites in experimental groundwater microcosms. Damiano is currently working as a postdoctoral researcher for Footprint Ecology.

Dr Astrid Willener (Supervisors: Dr Lewis Halsey, Professor Anne Robertson, Dr Siobahn Strike).
Astrid investigated the onshore life of king penguins. This involved studying their energy expenditure and biomechanics and understanding their physiological stress-response.

Dr Phil Collins (Supervisors: Dr Lewis Halsey, Dr Peter Shaw).

Phil studied the behavioural physiology and ecology of nesting kittiwakes, both in the UK and in the US.
