The University wishes our staff to reflect the diversity of society and thus welcomes applications from all qualified candidates regardless of personal background.

The project
In this project we will address fundamental problems at the interface of physics and biology: “How can cells control processes in space and time to achieve a fine-tuned regulation? To uncover this fundamental question, we aim to understand the formation of liquid, biomolecular condensates and how these are maintained and dissolved. This presents a horizon both to statistical physics but also in cellular biology. It is known that cells can use liquid-liquid phase separations to produce condensates at distinct locations in space to enhance specific processes. To stimulate the production of proteins, transcription factors play a fundamental role, and they have been revealed to show oscillatory dynamics; however the evolutionary advantage of this remains unknown. We exptect that this dynamics can guide and control this formation and stimulate downstream targets maybe through genetic resonance allowing the cell a new degree of control and cellular decisions. New results also indicate that the formation of transcriptional hotspots is dictated by the formation of biomolecular condensates and that condensates of receptors occur at the cell membrane. It is the goal of this project to establish a bridge between the dynamics of transcription factors with the formation of condensates to understand how complex life creates fine-tuned regulation.

Who are we looking for?
We are looking for candidates within the field(s) of physics, computational biology or similar. The successful candidate will have excellent skills in theoretical physics, in particular: statistical physics, dynamical systems, numerical techniques. A basic knowledge of cellular biology is also expected. The candidate should hopefully be extremely enthusiastic about scientific research and be very imaginative with the ability to work independently and in a team.

Our group and research- and what do we offer?
Our group studies complex and biological systems with methods from physics in order to obtain a fundamental understanding of the complex phenomena that can emerge. Our theoretical approach combines analytical calculations with computational simulations and data analysis from our collaborative experimentalists. The members of the group provide a balanced mixture of postdocs, PhD students, and undergraduate students. We conduct curiosity-driven basic research. We have strong collaborations with scientific groups in Harvard, Bangalore, Paris, Göttingen and Taiwan and the successful candidate is encouraged to visit several international collaborators.

The group is a part of The Niels Bohr Institute, Section for Biocomplexity, Faculty of SCIENCE, University of Copenhagen. The Section provides a strong, international environment for research in the field of Systems Biology located at Jagtvej 155, 2200 Copenhagen N. The Section currently employs 7 principal investigators, 1 technician, 10 postdocs, 20 PhD students as well as a number of undergraduate students.

We offer creative and stimulating working conditions in a dynamic and international research environment.

Principal supervisor isAst. Prof. Mathias Spliid Heltberg, heltberg@nbi.ku.dk, Phone: +45 26191889.
