Postdoc position in dispersal simulation of floating material in satellite-derived ocean currents (1.0 FTE)
Ongeveer 23 uur geleden - Universiteit Utrecht (UU) - Utrecht
Within the European consortium Epic-XS three 2-year Proteomics Postdoc positions are available.
Our laboratory, a world-leader in the field of proteomics, emphasizes its work on the development of advanced mass spectrometry-based methods to address questions in proteomics and structural biology. The laboratory houses an excellent infrastructure, including a dozen state-of-the-art mass spectrometers, advanced separation technologies, bioinformatics, and laboratories for cell culture, biochemistry and molecular biology. The research group Biomolecular Mass Spectrometry and Proteomics is vibrant and houses over 15 nationalities - Utrecht is a great place to be!
For all three positions, the work is embedded in the European Proteomics program Epic-XS and participation in international meetings for this consortium is expected. The aim is to implement the developed technologies into the access sites, promoting collaborations.
The Scheltema laboratory focusses on the development and application of cross-linking mass spectrometry (XL-MS) to study protein-protein interactions. This technology utilizes small and agile reagents that covalently connect amino acids in close proximity. After proteolytic digestion, mass spectrometry can identify the connected amino acids. From these identifications distances constraints are derived that can be placed in in protein 3D structures, either known or directly predicted using this information. The structural details, at a resolution in the range of a few nanometers, allow resolving interaction interfaces between proteins. This can be done either in-vitro or in-situ in a close-to-native environment, making XL-MS an incredibly powerful approach for cell and structural biology. For this position, you will join a team of dedicated researchers combining expertise in bioinformatics, biochemistry, mass spectrometry, and structural modeling on a variety of systems and organisms to answer cutting-edge questions in biological sciences. You are expected to apply size-exclusion chromatography and sucrose gradient ultracentrifugation to purify interesting protein assemblies, perform the cross-linking and mass spectrometry assays, perform data analysis and integrate the data into structural models. As part of the European Proteomics program Epic-XS you will interact and collaborate with international researchers and develop new methods for cross-linking mass spectrometry.
Recent illustrative work
Translational proteomics has made significant progress in recent years with improved protocols for the analysis of clinically important samples such as patient biopsy tissue material and different types of liquid biopsies. The analysis of patient tissue material allows the investigation of the disease state and the treatment response directly in the native in vivo environment and thereby provides valuable molecular disease information with high translational capacity. To make translational proteomics a main technology in clinical settings, several challenges need to be addressed. Here, we will focus on tissue biopsies, as the life in vivo setting, and extracellular vesicles (EVs), which potentially contain biomarkers for diagnosis and prognosis of disease conditions. Proteomics approaches will consist of high-end shotgun proteomics and targeted proteomics (e.g. DIA and SRM). For this position, we seek a highly motivated Biochemist or Analytical Chemist with proven expertise in mass spectrometry and clinical proteomics. You will join a team of dedicated researchers combining expertise in biochemistry, analytical chemistry, mass spectrometry and bioinformatics on a variety of systems to answer pressing clinical questions. As part of the European Proteomics programme Epic-XS you will interact and collaborate with international researchers and develop new methods to translate proteomics results in clinically relevant information.
Recent illustrative work
In recent years we have been developing new mass analyzers and new fragmentation techniques targeted towards the direct analysis of intact proteins and protein complexes by native and top-down proteomics. Such analyses on the one hand allow us to directly probe stoichiometries and structures of large protein assemblies, like viruses and ribosome particles, on the other hand they make it possible to identify and quantify distinct proteoforms of proteins highly modified by post-translational modifications such as phoshoproteins and (plasma) glycoproteins. Introducing charge detection single particle mass spectrometry and ECD and UVPD fragmentation on Orbitrap platforms has provided us with an unprecedented toolbox to discover so far little explored relevant parts of the proteome. For this position, we seek a highly motivated Biochemist or Analytical Chemist with proven expertise in biomolecular mass spectrometry. Having your own project, you will join a team of dedicated researchers combining expertise in bioinformatics, engineering and instrument development, biochemistry, analytical chemistry, and structural biology, and work on a variety of systems and organisms to answer cutting-edge questions in biological sciences. As part of the European Proteomics program Epic-XS you will interact and collaborate with international researchers and develop new methods for native mass spectrometry and top-down proteomics.

The positions are part of a European consortium providing high quality access to non-proteomics laboratories.
In addition to the employment conditions laid down in the cao for Dutch Universities, Utrecht University has a number of its own arrangements. For example, there are agreements on professional development, leave arrangements and sports. We also give you the opportunity to expand your terms of employment yourself via the Employment Conditions Selection Model. This is how we like to encourage you to continue to grow.
