Our research themes

Individual PhD projects will address one or more of six primary ECORISC research themes, identified as priorities for research in recent horizon scanning exercises and through our interactions with our associated partners in industry, government and third sector organisations.

Detection, fate, transport and uptake of chemicals in the natural environment 

Projects will develop novel sampling and analytical techniques to quantify emerging and novel chemicals in water, soil, sediment and biota and new models for assessing the bioavailability and uptake of chemicals into biota. Compound-specific analytical methods along with untargeted screening approaches will be used to provide an assessment of the full range of chemical stressors present in environmental media. 

Development of mechanistic understanding of the integrative effects of chemicals on individuals

Projects will combine transgenic and epigenomic technologies, in vitro, in vivo testing and the adverse outcome pathway (AOP) approach to develop an understanding of the effects of chemicals at molecular, cellular and tissue levels and how these effects translate to impacts on individual organisms. This will include seeking translation (read-across) from in vitro to in vivo for reducing and avoiding the use of animal models in chemicals testing. 

Extrapolation of effects measured on individuals to impacts on populations and communities and the ecosystem services they provide

Projects will develop and apply ecological understanding and modelling approaches to extrapolate from empirically derived (eg toxicity test) or predicted (eg AOP) individual-level endpoints to potential risk to ecosystem functions and the services they deliver.

This will include developing the mechanistic understanding and modelling approaches required to:

• extrapolate across levels of biological organisation, extrapolate from tested to untested species and extrapolate from structural to functional endpoints
• integrate chemical effects on individual species to enable the prediction of their combined effects on community structure, ecological processes and ecosystem services.

Effects of chemical mixtures, including in combination with other environmental stressors

Projects will develop an understanding of the mechanistic basis and long-term effects of mixtures on ecosystems and new modelling frameworks for assessing the risks arising from the combined effects of chemicals and other stressors.

Landscape-scale risk assessment across different spatial and temporal scales

Projects will develop approaches for assessing temporal and spatial variation in the vulnerability of communities within real landscapes to chemicals. Projects will integrate an understanding of the factors and processes that influence the types, concentrations and bioavailability of chemicals in the environment with an understanding of the ecological and ecotoxicological processes that influence the sensitivity and recovery of species and communities exposed to chemicals and other stressors.

A landscape-scale understanding is essential to developing a systems-based approach to chemical assessment and management.

Translation of environmental risk science into practice

Projects will explore how cutting-edge pollution science can be most effectively incorporated into the design, assessment and management of chemical products and will develop new frameworks for chemical prioritisation and risk assessment.

Training

The ECORISC experience

As an ECORISC student you'll embark on a just under four year journey designed to take you from a novice researcher to an effective and influential environmental specialist who has the skills and expertise required to undertake high quality interdisciplinary research necessary to solve real world challenges associated with managing chemical risks.

You'll work on a challenging research project and receive high quality training in environmental pollution science, transferrable and specialist skills. Through the close involvement of our associated partners in the design and delivery of the training programme, year group challenge events, student mentoring and their hosting of secondments and internships you'll gain experience of working in a real world environment.

Core training programme

Over the first two years of your ECORISC PhD programme you'll receive subject-specific training, delivered in collaboration with our partner organisations, in:

• ecotoxicology
• environmental chemistry
• ecology
• risk assessment
• core skills required for an environmental specialist.

On successfully completion of the programme you'll secure phase 1 of the SETAC Certified Risk Assessor (CRA) qualification.

Yearly challenge events

One week challenge events held each July will bring each year group together in a residential setting to address real world scenarios linked to chemical risk management and to enhance cohort cohesion. Delivered in collaboration with our associate partner institutions, these challenges will provide an opportunity for you to use knowledge and skills gained during the core training programme and your individual research project. These events will be designed to promote the interdisciplinary thinking and clarity of communication required when applying chemical risk assessment in the real world.

1st Year – Data challenge event

You'll be hosted by associated partners, including the Rivers Trust and Simomics, who have access to substantive ‘data’ sets and data analysis and interpretation platforms. You'll be challenged to analyse and interpret the data to address a real world question and will be introduced to regulatory monitoring data sets, giving you hands on experience in the review and quality assessment of data and of the use of software tools for complex dataset analysis.

2nd Year - Product-based risk assessment

Under the guidance of our business partners such as AstraZeneca, Bayer, Reckitt Benkiser, Syngenta and Shell you'll work in teams to perform an environmental risk assessment of a new to market chemical product. You'll develop and present a short ERA report, which will be scrutinised by our regulatory and third sector partners.

3rd Year - Science to policy event

Our final event will be delivered in collaboration with our policy partners such as Defra and JNCC. You'll take a ‘hot’ environmental topic and through role playing exercises you'll explore how best to translate the underlying science in the area to a policy outcome and communicate that outcome to a non-specialist audience. The challenge will end with a mock House of Commons Environmental Select Committee hearing. 

Secondments and internships

You'll be required to undertake two workplace experiences based with our partner organisations. Internships will be short in duration (two to four weeks) and will give you a taste of what it is like to work in a partner organisation.

During secondments, which will be longer, you'll work on a project defined in consultation with the partner hosting the secondment and your supervisory team.

Students

Equality, diversity, & inclusion

Equality, diversity, and inclusion

Equality, diversity, and inclusion is at the heart of the ECORISC CDT and we employ a range of approaches and mechanisms to tackle inequalities in the PGR recruitment, research, and training journey.

For example:

• CDT opportunities are advertised widely and promoted to a diverse base of talented graduates using language and imagery that is inclusive and screened for unconscious bias using tools such as Textio.
• We include equality statements in our adverts to encourage students who may otherwise not apply.
• We run virtual open days to introduce the CDT to potential applicants, explain the application process and answer any questions the students might have. A second workshop provides candidates who reach stage 2 in our application process with guidance on the submitting a written application, meeting with supervisors, presentations and interviews.
• We facilitate flexible working arrangements, including part-time working.
• We have developed a novel structured and three-stage interview and selection process that aims to evaluate applicants based on competencies and personal attributes as well as academic excellence and which minimises bias.
• Our recruitment approach aims to increase the focus on motivation and competences and reduce the importance of grades and the university attended. For instance, potential supervisors assess applicants based on anonymised applications and apply a scoring system that emphasises research potential rather than educational privilege.
• We organised a Summer Scholarship Training Scheme which aimed to provide potential PhD students from under-represented groups within the environmental science community a flavour or what it's like to study for a PhD. Scholars were given skills training in the methods and techniques used in environmental chemistry, ecotoxicology and environmental risk assessment. Training and mentorship on the PhD application process also featured within this scheme.
