About the Project
This understanding is critical because process optimisation and post-digestion sanitisation that do not require the energy inputs of high temperature pasteurisation (which is also not practical in some circumstances e.g. small-scale systems, developing countries) could make energy generation through AD more sustainable and more widely viable.
The project aims to:
1) evaluate pathogen/ARG content of common AD feedstocks
2) understand the role of feedstock type and process conditions on pathogen/ARG persistence
3) compare persistence of pathogens/ARG in traditional organic waste-amended soils vs. digestate-amended soils.
The proposal provides structural guidance and relevant support to ensure students can succeed and generate novel data to present at institutional, national and international level conferences and high-quality journal papers. The student will have access to expertise on environmental engineering (Surrey), facilities to establish mesocosm scale anaerobic digesters (Hutton) access to a state-of-the-art microbiology laboratory with expertise in the pathogen-related microbiology of AD (Avery) and to expertise in environmental risk assessment (Hough). The supervisory team has existing links with AD operators at different scales and utilising different feedstocks, therefore access to sampling locations is readily available.
The University of Surrey’s Doctoral College supports the academic and professional development of postgraduate researchers. The Doctoral College will facilitate excellent supervision, deliver training, and enhance postgraduate researchers’ professional skills. The University of Surrey offers training and support via the Researcher Development Programme (RDP), providing development opportunities for postgraduate research students across the University. The RDP offers workshops, tailored events, one-to-one coaching and other personal development opportunities to all the postgraduate researchers.
Students at the James Hutton Institute have access to statistics courses through BiOSS and are part of a lively and vibrant graduate school which hosts an annual symposium and a number of other events and courses. The student will have the opportunity to learn molecular microbiology, field sampling skills, environmental microbiology and risk assessment skills.
The James Hutton Institute has strong links with Scottish Water (e.g. Deerdykes AD) farm scale AD operators (e.g. Gask Farm, Turriff) and our intention is to arrange for the student to spend time with these organisations as part of their training. Conversations have been initiated with potential partners to this effect.
Applicants should hold or expect to gain a minimum of a 2:1 Bachelor Degree, Masters Degree with Merit, or equivalent in biological sciences, environmental science, environmental engineering or a related topic. They will show an aptitude for understanding process control and working in a precise manner. They should be a self-starter with the confidence to interact with a wide range of contacts from academic to laboratory staff and industrial contacts and they must demonstrate enthusiasm and willingness to learn. Experience in microbiology, molecular biology or environmental engineering would be advantageous.

Due to UKRI rules, the DTP can only fund a very limited number of international students. We will only consider applications from international students with an outstanding academic background placing them in the top 10% of their cohort.
