Background:
Recently, the possibility to differentiate human iPSCs into organized 3D structures, brain organoids, has provided an efficient tool to study neuronal development in a more advanced model than classic 2D cultures with mature neurons and advanced tissue architecture. Brain organoids are formed by cellular self-organization of neurons and astrocytes, resulting in the formation of distinct and interdependent brain regions ex vivo. Moreover, brain organoids developed over extended periods exhibit active neuronal networks, including the formation of organized and active synapses. The cellular diversity and 3D organization observed in brain organoids represent an advantage for modelling complex interactions observed in the neural microenvironment, including synaptic transmission in synaptosomes.

The project aims at characterizing the molecular processes in developing brain organoids using quantitative proteomics, modification specific proteomics (PTMomics), metabolomics, bioinformatics and imaging.

Location of the project:
The project is located in the research group of Professor Martin R. Larsen, Department of Biochemistry and Molecular Biology at the University of Southern Denmark.

The Larsen research group is part of the Protein Research Group (PRG) at the University of Southern Denmark (sdu) in Odense, Denmark. Odense is located only one hour from the main capital of Denmark, Copenhagen. The PRG was founded 45 years ago by the recognized protein and biological mass spectrometry researcher Professor Peter Roepstorff and is internationally recognized for their contributions within biological mass spectrometry, proteomics, biomedical research and clinical proteomics. Today, the PRG consists of a large research environment with nine individual research groups and more than 60 scientists, postdocs and students who share laboratory facilities and research environment. The PRG has a fantastic student environment with many multicultural inputs.

The PRG has the newest mass spectrometers for biological mass spectrometry applications including one Orbitrap Fusion Lumos Tribrid, one Orbitrap Eclipse Tribrid, two Orbitrap Exploris and two Q-Exactive HF. In addition, the PRG has a large fully equipped protein chemistry/proteomics laboratory, cell laboratory facilities and bioinformatics that will be available for the present project.

The Larsen group has for the past 20 years developed a large number of methods for assessment of PTMs in proteomics, including the Titanium Dioxide method (Larsen MR et al., Mol. Cell. Proteomics 2005) used by many research groups worldwide for isolation of phosphorylated peptides for characterization of signal transduction pathways in mammalian systems. The Larsen group research focus is centrered on investigation of the role of PTMs in system biology and biomedicine and development of new innovative methods for assessment of PTMs in biological samples. The Larsen group has a significant amount of national and international collaborations and is publishing in higher ranging journals.

Qualifications
A successful candidate should preferentially have a Master's or Honour's degree in cell biology, molecular biology, proteomics or a related field and should be highly motivated and innovative. A candidate with significant experience in brain organoids, functional proteomics, post-translational modification analysis, LC-based mass spectrometry and bioinformatics is preferable. Excellent communication and writing skills and an ability to interact socially and scientifically with other laboratory members and collaborators are essential.
