PhD Position in Chemistry with Specialization in Environmental Chemistry – Fate of PFAS in Thermochemical Conversion of Biomass and Industrial Waste Umeå University in Sweden

Umeå University, a leading Swedish institution recognized for its world-class research and education, is offering a fully funded PhD position in Chemistry with a specialization in Environmental Chemistry. The project focuses on the fate of per- and polyfluoroalkyl substances (PFAS) during thermochemical conversion processes involving biomass and industrial waste materials. PFAS are a diverse group of fluorinated organic compounds widely used in industry and consumer products, but their persistence, bioaccumulation, and toxicological effects have raised significant environmental and health concerns. The research aims to elucidate the fate, distribution, and degradation pathways of PFAS during processes such as pyrolysis, gasification, and hydrothermal upgrading, and to assess their presence in process outputs. Experimental work will be conducted both at Umeå University's Department of Chemistry and in collaboration with the Netherlands Organization for Applied Scientific Research (TNO), leveraging both lab-scale and upscaled facilities. The position is part of the Industrial Doctoral School (IDS), providing interdisciplinary training, a tailor-made course package, and a three-month internship with the external partner. Applicants must hold a second-cycle degree or equivalent, with substantial coursework in chemistry or a closely related field, and demonstrate strong English language skills. Experience in environmental, analytical, combustion, or organic chemistry is advantageous. The position is for four years of full-time doctoral studies, with possible extension for teaching duties. PhD students at Umeå University receive a competitive salary and comprehensive social benefits. The application deadline is January 2, 2026, and the anticipated start date is April 1, 2026, or as agreed. Applications should be submitted via the university's Varbi e-recruitment system and must include a personal letter, CV, degree certificates, transcripts, relevant publications, and references.
