PhD Studentship: Taking the forever out of forever chemicals –destruction of per- and poly fluoroalkyl substances (PFAS) in mixed matrices

University of Surrey - Chemical and Process Engineering

Research by the team currently focuses on different aspects of PFAS (per- and poly-fluorinated alkyl substances) sonolysis. This project will aim to engineer and test a new approach that compliments current work by the group with industrial relevance. Sonolysis via high frequency ultrasound is one of few technologies able to fully mineralise PFAS. However, PFAS bound to solids (sorbents and soils) create a technical challenge for direct sonolysis. This project will research and develop solutions for this challenge, alongside consideration of mixed contamination matrices.

Mixed contamination matrices present a challenge for analysis and the project will require significant engagement with i) chemistry of PFAS destruction in mixed matrices, ii) engineering technical solutions and iii) development and implementation of analytical protocols (LCMS, ion analysis)

The candidate will be part of a larger group working on different aspects of sonolysis challenges (~8 PGRs, led by Dr Bussemaker), alongside a well-equipped mass spectrometry group (5 PGRs led by Dr Sears) in collaboration with company sponsors, Mantisonix. Close collaboration with Mantisonix will involve a minimum 3-month secondment at the company over the course of the PhD (located in walking distance from the university). The largely practical work will involve attendance at the university/company ~4 days per week. Working from home, part time and flexible hours will be accommodated for individual needs where possible.

Supervisors: Dr Madeleine Bussemaker, Dr Patrick Sears and Dr Vinicius Diniz

Entry requirements

Open to candidates who pay UK/home rate fees. See UKCISA for further information. Starting in July 2026. Later start dates may be possible, please contact Dr Madeleine Bussemaker once the deadline passes.

You will need to meet the minimum entry requirements for our PhD programme.

Selection criteria – please include a statement against the criteria in your cover letter:
