We invite applications for a two-year Postdoc position within the ERC project DynanoNet, which aims to develop materials, methods, and technologies that enable adaptive separation of molecules and particles using dynamically tunable nanofibril networks. You will perform coarse-grained molecular dynamics simulations to study the transport of solvents, molecules, and particles through nanofibril networks and investigate the influence of network topology.
You will use and compare two approaches: (1) an ESPResSo coarse-grained model developed at KTH providing high spatial and temporal resolution to capture detailed particle–network interactions and (2) a supra coarse-grained model combined with the lattice-Boltzmann approach developed at the laboratory of organic electronics (LOE) at Linköping University. You will collaborate within the DynanoNet project to combine experiments and simulations.
Your principal supervisor will be Dr. Tobias Benselfelt, with assistance from Dr. Ahmad Reza Motezakker at KTH and Dr. Aleksandar Mehandzhiyski at LOE. In addition, you will work in a world-leading focus group on simulating nanofibril networks, including Dr. Ahmad Reza Motezakker, Dr. Tomas Rosén, Professor Jakob Wohlert, and Professor Daniel Söderberg at KTH, and Dr. Aleksandar Mehandzhiyski and Professor Igor Zozoulenko at LOE. You will assist in coordinating this collaboration.
A position at a leading technical university that generates knowledge and skills for a sustainable future
Engaged and ambitious colleagues along with a creative, international and dynamic working environment
Opportunity to work in a multidisciplinary research group that studies everything from fundamental physics and chemistry to applied research in electronics.
Opportunity to work in a team with leading researchers in simulations at KTH and the Laboratory of Organic Electronics at Linköping University.
Work in Stockholm, a vibrant city close to nature.
As a person, you are curious, motivated, and independent. We also see that you are structured in your work, take responsibility for the project, and have excellent research expertise. You are also collaborative and proactive in seeking assistance to drive this project forward. You also need to have:
A doctoral degree (Ph.D.) or an equivalent foreign degree. This requirement must be fulfilled no later than the time the employment decision is finalized.
Prior experience with simulations in the field of chemistry.
Proficiency in English, which is needed for the daily work.
Excellent written and verbal communication skills.
Preferred qualifications
A doctoral degree or an equivalent foreign degree, obtained within the last three years prior to the application deadline
A background in physical chemistry, surface and colloid science, or polymer physics.
Previous experience with coarse-grained simulations in ESPResSo 4 and/or LAMMPS simulation packages
Previous experience with diffusion in porous materials, nanofibrillar networks, or membrane/gel filtration.
Awareness of diversity and equal opportunity issues, with specific focus on gender equality
Log into KTH's recruitment system to apply for this position. You are responsible for ensuring that your application is complete according to the instructions in the ad.
Your complete application must be received at KTH no later than the last day of application, midnight CET/CEST (Central European Time/Central European Summer Time).
About the employment
The position offered is for, at the most, two years.
A position as a postdoctoral fellow is a time-limited qualified appointment focusing mainly on research, intended as a first career step after a dissertation.
Others
Striving towards gender equality, diversity and equal conditions is both a question of quality for KTH and a given part of our values.
It may be the case that a position at KTH is classified as a security-sensitive role in accordance with the Protective Security Act (2018:585).
