Ecology, Conservation and Zoonosis PhD

I am keen to supervise projects that examine the effects of management and changing abiotic and biotic conditions on plant community, functional traits, physiology and multitrophic diversity. I am keen to use a range of novel approaches such as genomics, remote sensing, drones and red edge sensor camera.聽 Projects that I have supervised include聽

• Extreme climate events and floodplain grassland plant communities: linking resilience to functional diversity (PhD)
• Understanding the demographics and genetic patterns of water voles in human modified landscapes (PhD)
• Influence of the distribution of green urban spaces on the cooling effect (MRes)

I鈥檓 interested in supervising postgraduate projects in all areas relating to remote sensing (RS) and geographical information systems (GIS) but particularly those which study ecosystems and ecosystem change and technological developments in relation to this. I currently supervise PhD students conducting studies in remote sensing, for example the assessment of economic drivers of Net Primary Productivity (NPP) from forested areas in the UK, and remote detection of river geomorphology using interferometry.聽 Recent PhD supervision successes have studied subjects such as remote sensing of carvings at Stonehenge, monitoring oil pollution in Nigerian mangroves, modelling seagrass growth in the Arabian Gulf, assessing wine quality from remotely detected vine characteristics, mapping disease prevalence in Cameroon, modelling sediment deposits on the river Lugg, and examining the statistical impact of trench mapping in archaeology. 聽I would like to encourage students to pursue their interests in this field by applying for PhD study or to join the taught MSc Geographical Information Systems and Environmental Management or the research focussed MRes GIS and Remote Sensing degrees at the 黑料吃瓜网 following undergraduate studies.

I am interested in supervising postgraduate research students in the area of ecotoxicology/marine biology:聽 pollutants impact on marine organisms, biomarkers of stress in aquatic invertebrates, microplastics as vector for marine pollutants, transgenerational effects of aquatic pollutants.聽聽

I am interested in supervising Masters and PhD students in the following areas: microbiology, healthcare, antibiotics, antimicrobials, bacteriophages, quorum-sensing, biofilms, water pollution, drinking water, waste water, zoonoses, environmental microbiology.

I welcome enquiries from prospective Masters, Ph.D. and postdoc applicants for research projects in wildlife ecology, conservation biology, and human-wildlife interactions. I currently supervise/co-supervise several graduate students and work with postdoc-level scientists on a range of mammal projects across 3 continents. Most of the work involves free-ranging terrestrial mammals, particularly carnivores in Africa, Europe and North America.聽

I am keen to supervise projects that examine any aspect of anthropogenic impact on the physiology, morphology and behaviour of aquatic organisms. Be that chemical or physical pollutants or barriers to migration. I am especially interested in the fisheries management aspects of this and how best to consider mitigation. Projects I have supervised are varied and range from behavioural observations of captive fish species, to microplastic ingestion of the mussel (Mytilus edulis) and the velvet swimming crab (Necora puber).聽In addition I am interested in aspects of aquaculture and how best to improve the sustainability of feeds. I also have an interest in the welfare of cultured individuals and how to improve habitats whilst being reared.

Example projects that I supervise include the following:

Microplastic pollution within Chichester Harbour (MRes)

Selective breeding of marine copepods聽(MRes)

Trophic transfer of microplastics in marine invertebrates (MRes).

Does watercress farming impact fish communities (PhD)

The impacts of sewage treatment effluents on the river shrimp聽Gammarus pulex聽(PhD).

The effects of simvastatin on the development and behaviour of early life stages of聽Danio rerio聽(Undergraduate)

Microplastic ingestion of marine copepods (Undergraduate)

The presence of microplastic fibres in the stomach of the Atlantic mackerel (Scomber聽scombrus) (Undergraduate)

The effects of titanium dioxide and zinc oxide on fish development and behaviour (Undergraduate).

The influence of aquarium visitors on captive elasmobranchs (Undergraduate).

Sexual dimorphism of the integument of sharks (Undergraduate).

I'm keen to supervise postgraduate research (MRes/MPhil/PhDs) in the following areas: development and application of low-cost and/or rapid diagnostic water quality tools; behaviour of micro-contaminants (particularly bacteriophages from the human gut) within natural and engineered environments environments and provision of water and sanitation within low-income and/or emergency settings.

To date I have overseen the supervision, career development and successful completion of 12 doctoral students from the UK, Italy, Portugal, Cameroon, Nigeria, Brazil and India. These PhD's have covered a range of topics such as 'Bacteriophages as Surrogates of Viral Pathogens in Wastewater Treatment Systems (Dias 2016)', Ecological Characteristics of the Enterococcal Surface Protein (esp) gene with reference to microbial source tracking (Yaliwal 2014); Low-cost physico-chemical disinfection of human excreta in emergency settings (Sozzi 2015); Bacteriophages as Indicators of Human Enteric Viruses in Mussels (Da Silva 2013); and UV Radiation Response of Bacteriophages of Human-specific Bacteroides (Diston, 2010) .

I am currently supervising a water industry-funded PhD student who is using cutting-edge source apportionment approaches to investigate drivers of pollution in Chichester, Langstone and Pagham harbours (S. England) and have just finished supervising a PhD on Pollution, plastics and plumes; understanding the behaviour of microplastics in aquatic sediments of the R. Thames catchment.

According to French Physiologist Claude Bernard - "The science of life is a superb and dazzlingly lighted hall which may be reached only by passing through a long and ghastly kitchen." Anyone who has undertaken a doctoral degree is likely to agree with this analogy (at least at some point during their journey). As a PhD supervisor, I see my role as someone who can potentially make the kitchen a little less ghastly, or the journey slightly less arduous. I strive to provide a聽highly connected, supportive, nurturing聽international research environment with聽the Environment and Public Health Research and Enterprise聽Group.

I am currently supervising a further 3 PhD candidates. My PhD students have originated from an equally diverse range of disciplines including Fisheries Engineering, Environmental Science, Biology, Biomolecular Science, Microbiology, Ecology, Environmental Management, Mathematics and have worked for NGO鈥檚 in Haiti (MSF), on Gates Foundation-funded research in India, on US AID-funded research into safe excreta disposal in emergencies (Cholera and Ebola treatment centres), led MRC-funded projects in Kenya, founded research groups in Brazil, and managed prestigious research laboratories in the US.

All have gone on to forge careers within the burgeoning field of Water, Sanitation and Hygiene (WASH) and or microbiology, either via academia, or industry.聽The sustained success of our thriving research group stems from a blend of enthusiasm for the wider subject area and from a long-held desire to break down barriers, to ensure that epidemiologists mix with engineers, and microbiologists work with modellers. This has been achieved by exchanging PhD students (and Early Career Researchers) with trusted and established international project collaborators within the public, private and voluntary sectors.

I聽also maintain a rolling programme of group activities, training initiatives and social events for new arrivals into the group, which is increasingly populated by previous PhD students who are even better placed to support the career aspirations of our current and future Doctoral students.聽With unsafe water supply and sanitation responsible for an estimated 842,000 deaths per year, the WASH sector continues to face significant challenges, which are only likely to be met through interdisciplinary, cross-border collaboration by a new generation of WASH-focussed researchers, capable of confidently sharing ideas across a range scientific domains and via an increasingly complex network of stakeholders and end-users. I hope that as my students continue to emerge into the 鈥榙azzlingly lighted hall鈥櫬爐hey are as well-rounded and well-placed as possible to meet this challenge.聽聽聽

I am happy to collaborate in projects and supervise post-graduate students in the broad field of medical and pharmaceutical microbiology, with a particular emphasis for projects involving clinically-relevant fungi and involving other healthcare-associated and non-academic industrial partners.

I am interested in supervising postgraduate research students in the following areas: micro-plastics, tri-trophic interactions, field population dynamics, pollination ecology & biodiversity in the urban landscape.
