As a PRISMAS PhD student, you will have the chance to conduct cutting-edge research in your field, taking advantage of state of the art tools that will bring to attractive future job opportunities in academia or industry. Moreover, you are part of designing the future of synchrotron technology and instrumentation and using these to tackle some of the most significant global challenges the world faces today while acquiring interdisciplinary and intersectoral knowledge. Being part of the PRISMAS programme gives you the one-of-a-kind experience in form of a secondment at the world´s first 4th generation synchrotron, MAX IV in Lund, Sweden. Complemented with a tailored training programme, including courses to build scientific and technical competence as well as strengthen transferrable skills, PRISMAS provides you with the skills, knowledge and competence needed to successfully achieve your doctoral degree.
Description of the workplace
At the Division of Theoretical Chemistry (Department of Chemistry at the Science Faculty), we study chemical processes with the help of computational methods, including quantum chemical calculations and statistical mechanics simulations. The aim is to understand chemical systems and processes at the molecular level, including interactions, structure and dynamics. The work is often done in connection with experimental studies. The division currently consists of nine senior scientist, five postdoctoral scientists and eleven PhD students.
The group of theoretical biochemistry is currently comprised of five PhD students and two postdocs. It aims at studying proteins using all available computational methods, from advanced quantum chemical methods and density- functional theory to molecular-mechanics methods, molecular dynamics simulations and free-energy calculations. The group has three focus areas: mechanisms of enzymes (mostly metalloenzymes), e.g. nitrogenase, lytic polysaccharide monooxygenase and particulate methane monooxygenase, ligand- binding calculations (drug development) and the combination of computational chemistry and experimental structure methods like X-ray or neutron crystallography, NMR and cryogenic electron microscopy (cryo-EM). The flagship for the latter project has been quantum refinement, a combination of X-ray crystallography and quantum mechanical calculations, which allows us to improve and interpret crystal structures. The group is led by Prof. Ulf Ryde (https: // www. teokem.lu.se/people/seniors/ryde), who received his PhD in 1991 and became a professor in theoretical chemistry in 2004. He has published 297 articles and has 19 900 citations and a h-index of 76.

The MSCA COFUND project PRISMAS offers you outstanding opportunities as well as a stimulating and inspiring surrounding for performing cutting-edge research. Supporting your mobility, it creates perfect conditions for strengthening your international network.
Work duties and responsibilities
You will develop and apply methods to combine quantum mechanical calculations with time-resolved X-ray crystallography of proteins.
X-ray crystallography has traditionally been the prime source of structural information of biological macromolecules. Such information is essential for the understanding of biomacromolecules and it is mandatory for any rational modification of these molecules, e.g. by mutagenesis or drug development. Recently, the development of powerful X-ray sources has opened the opportunity to collect series of structures during dynamic events or during reactions using time-resolved crystallography methods. A challenge for these methods is to interpret the data. Since synchronisation of the dynamic event is never perfect, the collected data typically reflect a mixture of structures, e.g. the reactant, product and intermediate states of a reaction, and it is a challenge to sort out what is really seen for the relatively poor resolution of biomacromolecules. Normally, the structures are interpreted as a mixture of states with non-unity occupancies, using empirical restraints to ensure that the structures make chemical sense. In practice, the results are often biased by what the crystallographer hope to see. Therefore, there is a need for more strict procedures for the refinement of time-resolved crystallographic structures. You will employ the quantum-refinement procedure developed in our group, which provides an ideal solution for mixtures of several states and provides an optimal compromise between the experimental data and the quantum mechanical calculations. When the electron density is ambiguous, the quantum mechanical calculations will give an unbiased and accurate interpretation of the density. The method will be combined with kinetic modelling of the reaction to provide an unbiased interpretation of the structure. An important part is to make the methods available for any crystallography user at MAX IV.
The training implies a secondment of 3-12 months at MAX IV laboratory in Lund, Sweden. Additional secondments and/or short stays may be arranged in agreement with the supervisor of the research project. Moreover, you will attend international conferences, participate in periodical project meetings and training schools as well as in specialised courses at different universities to complement your knowledge. A certain amount of travelling is foreseen in relation to these activities.
You must have MSc, civil engineer or an equivalent education in chemistry, physics, bioinformatics or similar. Practical experience of theoretical chemistry methods (quantum chemistry, molecular dynamics, free energy perturbations, etc.) and practical experience with crystallography are qualifying, as are programming skills and courses in quantum mechanics, statistical mechanics, physical chemistry, mathematics, and crystallography.
Students with basic eligibility for third-cycle studies are those who have completed a
The employment of doctoral students is regulated in the Swedish Code of Statues 1998: 80. Only those who are or have been admitted to PhD-studies may be appointed to doctoral studentships. When an appointment to a doctoral studentship is made, the ability of the student to benefit from PhD-studies shall primarily be taken into account. In addition to devoting themselves to their studies, those appointed to doctoral studentships may be required to work with educational tasks, research and administration, in accordance with specific regulations in the ordinance.
To comply with the mobility rule of the MSCA COFUND programme, you are eligible if you have not resided in Sweden for more than 12 months during the period 2020-05-01 to 2023-05-02 for your main work or studies.
By the employment date (before 01/09/2023) you must have completed courses of at least 240 credits, of which at least 60 credits are from second-cycle courses, have been awarded a Master´s degree or have acquired largely equivalent knowledge in some other way, in Sweden or abroad.
In addition to the criteria abovementioned, you must have fulfilled a second cycle education in a relevant field, such as chemistry, physics, bioinformatics.
You are eligible for the PRISMAS programme, if you are a doctoral candidate, i.e., are not already in possession of a doctoral degree.
Type of employment
Limit of tenure, four years according to HF 5 kap 7§.
