13 PhD positions at Wetsus, European Centre of Excellence for Sustainable Water Technology

There are 13 PhD positions available at Wetsus, a company that focuses on “Sustainable Water Technology”. More information can be found here.


PhD position on the Photochemistry and Scale-up of Chemical-free Advanced Oxidation Processes by Vacuum UV Light for Water Treatment

Wetsus offers an exciting PhD opportunity for a dynamic personality, at the interface of high quality scientific research and cutting-edge technology development within its internationally recognized PhD programme.

The objective of the PhD project is to develop and validate new reactor concepts for photochemical water treatment that make use of vacuum UV radiation at 185 nm provided by low pressure mercury lamps besides the emission line at 254nm. The PhD candidate will design a new reactor modifying geometry, flow patterns and reagents. Experimentation will analyse the suitability of the rich photochemistry provided by vacuum UV irradiation to eliminate anthropogenic micropollutants in the presence of organic and inorganic constituents of drinking water and secondary effluent. The PhD candidate will specifically verify that the risk for generating secondary water quality hazards, e.g. unwanted byproducts, is not increased compared to the current AOPs. Verification and data analysis as well as design of new reactors will be supported by advanced numerical modelling techniques including chemical models, flow models (Computational Fluid Dynamics), and irradiation models, which will in fact constitute a main tool used by the PhD candidate. The PhD project thus entails two major parts: photochemical experiments and numerical modelling. The PhD candidate should have demonstrated expertise in at least one of these fields and preferably both.

The PhD project will benefit from the extensive collaboration already taking place among the various institutions involved in this theme. As such, the Ph.D. candidate selected for this project will be requested to travel in various geographies where some sponsoring institutions are headquartered (Spain, Canada and UK, beside Netherlands) and spend some periods of this doctorate in the form of internships in their premises.The candidate will conduct the PhD in a dynamic environment within the Wetsus Priority Compounds Research Theme under the supervision of promoter and co-promoter(s). Dr Wolfgang Gernjak (Catalan Institute for Water Research, Spain) will be the principal promoter and advise the candidate on water quality aspects. Dr Bas Wols will be responsible for the day-to-day supervision at Wetsus and Dr. Domenico Santoro will contribute with modelling expertise to the PhD project. The PhD will be carried out in close collaboration with the industry members of the Wetsus Research Theme, most notably Trojan Technologies, PWN Technologies and Anglian Water. Wetsus provides further opportunities for complementary training within its PhD programme, e.g. on required technical skills, but also so-called soft skills.

PhD position Computer Assisted EEG Diagnostics in Epilepsy

The electroencephalogram (EEG) is a most valuable tool in the diagnostic process of epilepsy. At present, the interpretation in a clinical setting is typically performed by visual analysis. Limitations of this approach include subjectivity, a long training period and the time needed for review.

This project aims to develop, evaluate and introduce a system that assists in the visual analysis of the EEG, both to improve efficiency and diagnostic accuracy. Important challenges include detection and classification of epileptiform discharges, the implementation of a decision algorithm and presentation of the results in a digestible format to the clinician. Proposed strategies include template matching for the detection of transients and machine learning. Finally, the system must be evaluated in a clinical setting, where it, ideally, performs like a human EEG expert to assist the neurologist or clinical neurophysiologist. This latter aspect is an important part of the project.

Candidates should have a Master’s degree in e.g. Computer Science, Applied Mathematics, Technical Medicine, Biomedical Engineering, Applied Physics or Electrical Engineering, with a strong interest in biomedical signal analysis, machine learning and interactions with clinicians or neurologists.
