The role
This Research Fellow position will contribute to a new project developing a biosensor-based approach for monitoring volatile fatty acids (VFAs) in anaerobic digestion.
The Successful Candidate Will
- Develop and test a pH-controlled silicone membrane separation approach to selectively transfer VFAs from complex digestate samples into a cleaner aqueous phase.
- Investigate the effect of key interfering species, particularly bicarbonate and chloride, on VFA separation and recovery.
- Support the development and optimisation of microbial fuel cell biosensors for monitoring acetate, propionate, butyrate and VFA mixtures.
- Carry out laboratory experiments, sample preparation and analytical measurements, and interpret the resulting data.
- Progress from controlled synthetic solutions towards validation using real anaerobic digestate.
- Work closely with the academic team and contribute to project reporting, data analysis and future research outputs.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
