The Rogge group, embedded within the multidisciplinary Center for Molecular Modeling (molmod.ugent.be) at Ghent University, Belgium, is seeking a highly motivated Ph.D. researcher to strengthen our team by conducting state-of-the-art computational research in functional materials design. The Ph.D. candidate will model amorphous materials and investigate how the strain in these materials impacts their macroscopic function. To this end, the candidate will need to train phase-transferable machine-learned interatomic potentials and establish workflows to uniquely characterise and fingerprint structures without long-range order. Answering these questions is vital to understanding how these realistic, finite-sized materials can be adopted in applications.
This position aligns with a recent Starting Grant (StG) STRAINSWITCH, awarded to prof Sven M. J. Rogge by the European Research Council (ERC). This grant aims to establish strain engineering as a new in silico approach to designing functional nanostructured materials (see, e.g., doi.org/10.1016/j.matt.2023.02.009). We especially welcome candidates with a strong track record who are – or may become – eligible to apply for a prestigious Ph.D. fellowship at our national funding agency or wish to prepare for a European fellowship.

It is often easy to observe the ability of polymorphic materials to undergo a phase transition through changes in colour, conductivity, photovoltaic efficiency, or other functional properties. In contrast, it is challenging to control under which external stimuli, such as stress, temperature, or adsorption, these materials switch. Yet, enabling such polymorphic materials design would be a game-changer for pressing societal challenges, from access to drinking water to producing green energy. However, this requires a firm understanding of how changing a material’s structure impacts its polymorphism and macroscopic function.
STRAINSWITCH aims to transform polymorphic material design by establishing the strain engineering concept. The central characteristic of this in silico approach is strain: the extent to which a material deforms due to external or internal triggers. On the one hand, external stimuli generate strain, even before they activate a phase transition. On the other hand, spatial disorder in a structure, tuneable from the atom to the device scale, also induces strain which interferes with external strain fields. Our fundamental idea is that it is possible to systematically predict which disorder is needed to ensure polymorphism only occurs under well-defined external triggers by balancing these internal and external strain fields.

More info about the CMM
The CMM groups about 40 researchers from the Faculty of Science and the Faculty of Engineering and Architecture at Ghent University with molecular modelling interests. It is unique in the university as it clusters computational researchers with various backgrounds, from multiple departments and faculties. The CMM aims to model molecules, materials & processes at the nanoscale by bringing together physicists, chemists, and (bio-)engineers while stimulating collaborations across disciplines. This multidisciplinary collaborative mission is the DNA of the CMM and is crucial in achieving scientific excellence in molecular modelling.
The CMM focuses on frontier research in six primary areas: computational material research on the nanoscale, model development, spectroscopy, many-particle physics, chemical kinetics in nanoporous materials, and bio-organic & organic chemistry. Our research is performed within a strong network of partners at Ghent University and at an (inter)national level. To pursue excellence, we strongly stimulate interactions between the various researchers in our team and our vast network of national and international partners. The prospective candidates will join a strongly connected research team and collaborate with national and international academic partners. The research of the CMM is internationally regarded to be at the forefront of its field.
Who are we looking for?
We are looking for a highly motivated Ph.D. candidate with:
- a Master’s degree or an international equivalent in physical chemistry, chemical physics, condensed matter physics, statistical physics, theoretical physics, or a related field obtained before your first working day at the CMM.
- demonstrated experience with coding (Python, C, etc.) and quantum chemistry software (Gaussian, VASP, CP2K, etc.) or force-field-based simulations is an advantage;
- a strong interest in molecular modelling;
- excellent research and scientific writing skills;
- perseverance and an independent, proactive working style;
- the willingness to look beyond the borders of your discipline and a solid motivation to work in a multidisciplinary team;
- high-level written and oral English communication skills with the ability to represent the research team effectively internally and externally, including presenting research outcomes at national and international conferences;
- above all, the ambition to be at the forefront of in silico nanostructured materials design.
What can we offer you?
A 4-years contract with an attractive salary. The selected candidate will moreover get the ability to strengthen their CV within the context of a strongly motivated and multidisciplinary research team and have the ability to contribute to challenging topical research to solve critical societal questions. They will have the opportunity to attend various international conferences and to include research stays in prominent international research teams in this field. Ghent University boasts a strong community that offers a broad range of training and career possibilities for Ph.D. candidates. The training opportunities focus on research and transferable skills such as time management, presentation, and leadership skills.
