PhD fellow in Structural Biophysics - The structure of membrane proteins under solution conditions studied by small-angle X-ray and Neutron scattering

A PhD position is available from April 1st, 2018, at the University of Copenhagen, Denmark under the NordForsk funded project “The structure of membrane proteins under solution conditions”.  
The project will be supervised by Prof. Lise Arleth (LA) at the Section for X-ray and Neutron Science, Niels Bohr Institute and Prof. Kresten Lindorff-Larsen (KLL) at the Linderstrøm-Lang Centre for Protein Science, Department of Biology, both at the University of Copenhagen. LA’s group focuses on X-ray and neutron small-angle scattering analyses on biomolecular structures and the associated modelling and data analysis. KLL’s group use molecular simulations and develop methods for integration of simulations with experimental data. Both research groups are highly interdisciplinary and international, and the PhD candidate will work in a vibrant and engaging research environment. 
The goal of the project is to obtain insight into subtle interplay between a membrane protein and its local lipid membrane and aqueous environments. The project combines molecular dynamics simulations and small-angle X-ray and neutron scattering to investigate their molecular structures. The central focus of the project will be to develop novel Molecular Dynamics based strategies for the structural analysis of small-angle scattering data of membrane protein systems. The project will also include developing novel statistical tools for the integration of heterogeneous sources of data with computer simulations. 
The PhD project is part of a larger Nordforsk-funded project that is executed collaboratively also with the research groups of Assoc Prof Marie Skepö (MS), Department of Chemistry at Lund University and Prof Jens Preben Morth (PM), Centre for Molecular Medicine Norway at Oslo University. 
The candidate will work with all four groups but be anchored at the Structural Biophysics group at the Section for X-ray and Neutron Science at the Niels Bohr Institute, with Prof Arleth as the main supervisor and Prof Lindorff-Larsen as the co-supervisor. The four groups combine membrane protein molecular and structural biology (PM), X-ray and neutron small-angle scattering methods, SAXS and SANS (LA and MS), and atomistic and coarse-grained molecular dynamics simulations to probe the structure and dynamics of biological molecules (KLL and MS), and development of methods for advanced data analysis (KLL and LA).  
The key molecular target of the project is the ATP driven magnesium transporter A, MgtA, from E. coli. The functioning of MgtA is, like for most other membrane proteins, closely linked to the properties of the surrounding lipid membrane and aqueous environments. The PhD project will combine experimental data, obtained in collaboration with PM’s group with molecular simulations conducted in parallel by the LA/KLL and MS groups to shed further light on the relevant processes. The project will focus on MD supported model development of membrane-solvent interaction and development of approaches for validation of the simulations against combined SAXS and contrast variation SANS on e.g. phospholipid bilayer vesicles and nanodiscs. The project will then expand this such that the SAXS/SANS data analysis and modelling of the MgtA can be handled, including incorporation of correct descriptions of protein-water, membrane-water and membrane-protein interfaces.  
Outstanding candidates with a strong background in physics, mathematics (applied or mathematical modelling), chemistry or biochemistry are preferred. Strong quantitative skills are essential and the ideal candidate has research interests and/or qualifications in one or more of the following areas: 
-Numerical competences, including programming experience and ability to set up advanced computer-simulations and handle large data sets   
-Experience in computational aspects of protein chemistry, including hands-on experience in molecular dynamics simulations (atomistic and/or coarse-grained)  
-Research experience with small-angle X-ray or neutron scattering on biological samples, preferably membrane protein and/or lipid membrane systems 
Applicants must document their successful MSc studies by a high grade point average. If the applicant’s MSc work has resulted in a publication (accepted or in draft) this is considered a strong advantage. Candidates must have good interpersonal and communication skills. Excellent English writing skills are a requirement.
