PhD student in Analytical Chemistry

The Department of Chemistry, with more than 200 employees, is one of the largest departments at Stockholm University. The Research spans all areas of chemistry such as analytical chemistry, physical chemistry, materials chemistry, inorganic and structural chemistry and organic chemistry. The research projects are many from theory to experiment, from basic research to more applied projects often focusing on sustainable chemistry but also advanced analytical methods of chemicals and materials. The department has a very well-developed research infrastructure with state-of-the-art equipment with qualified support from staff scientists.

The department also hosts the Bachelor's degree programme in chemistry and three Master's programmes: analytical chemistry, sustainable chemistry, and organic chemistry. PhD programmes are conducted in five areas: analytical chemistry, physical chemistry, materials chemistry, inorganic chemistry and organic chemistry.

Subject area

Project title: Identification of high toxicity and exposure chemicals in environmental samples with non-target screening

This project aims to discover toxic and structurally novel chemicals in liquid chromatography high resolution mass spectrometric data (LC/HRMS) used for non-target analysis. The projects aims to develop a complementary workflow of machine learning models and analytical methods to retrieve and evaluate the candidate structures of chemicals detected in non-target screening. For this purpose combination of supervised and unsupervised machine learning strategies will be used. Chromatographic separation, ion mobility, tandem mass spectra, and other analytical characteristic extractable from LC/HRMS data will be considered.

The ideal applicant is proactive and equipped with a problem-solving mindset. The ambition to conduct interdisciplinary research on the interface machine learning, liquid chromatography, and mass spectrometry is essential. Candidates with experience with machine learning, chromatographic separation, and high resolution mass spectrometry data are encouraged to apply. The applicant should have a good knowledge of English, both orally and in writing.

Qualification requirements

In order to be admitted to postgraduate education, the applicant must have the general and specific entry requirements. The qualification requirements must be met by the deadline for applications.

You meet general entry requirements if you have completed a second-cycle degree, or completed courses equivalent to at least 240 higher education credits, of which 60 credits must be in the second cycle, or have otherwise acquired equivalent knowledge in Sweden or elsewhere.

To meet the special entry requirements to be admitted to doctoral level education on analytical chemsitry, the applicant must have completed courses in chemistry worth at least 90 credits in undergraduate education, and have successfully completed a course in analytical chemistry at advanced level worth at least 15 credits and an independent project at advanced level worth at least 30 credits.

Selection

The selection among the eligible candidates will be based on their capacity to benefit from the training. The following criteria will be used to assess this capacity: the candidates’ documented knowledge in a relevant field of research, written and oral proficiency in English, the capacity for analytical thinking, the ability to collaborate, as well as creativity, initiative, and independence. The assessment will be based on previous experience and grades, the quality of the degree project, references, relevant experience, interviews, and the candidate’s written motivation for seeking the position.

About the employment

We offer a fixed-term employment as a doctoral student according to Chapter 5 of the Higher Education Ordinance (1993:100). The period of employment may not be longer than what corresponds to full-time doctoral education for four years. As a doctoral student, you should primarily devote yourself to your own doctoral education, but the employment may include work with education, research and administration to a limited extent (maximum 20 %).

A new employment as a doctoral student is for a maximum of one year, the employment is then renewed for a maximum of two years at a time.

Stockholm University strives to be a workplace free from discrimination and with equal opportunities for all.
