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.

Project description

Project title: Pinpointing toxic chemicals from mass spectrometric data with supervised and unsupervised machine learning

Supervisors: Prof. Anneli Kruve (main supervisor); Prof. Jonathan W. Martin (co-supervisor)

This project aims to discover toxic and structurally novel chemicals in high resolution mass spectrometric data (HRMS) used for non-target analysis. The projects aims to develop a combination of supervised and unsupervise machine learning stragaties for pinpointing chemicals that have high toxicity. For this purpose different clustering, encoding , and regression techniques will be used and combined. It will address research challenges in dealing with toxicity data, multidimetional HRMS data as well as decoding structure relevant information from spectral data. Furthermore, complementary chromatographic methods for detection of highly polar and highly volatile chemicals will be developed.

The ideal applicant is proactive and equipped with a problem-solving mindset. The ambition to conduct interdisciplinary research on the interface of toxicity, machine learning and mass spectrometry is essential. Candidates with experience with toxicology, machine learning or handling high resolution mass spectrometry data are encouraged to apply. 

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:

• Documented knowledge in a relevant field of research
• Capacity for analytical and creative thinking
• Initiative
• Independence
• Ability to collaborate
• Written and oral proficiency in English.
