PhD: Resolving structure-function relationship of cytoskeletal proteins in mammalian cells by quantitative analysis of single-molecule localization data.

Job description
In order to keep human bodies healthy, cells have to continuously adjust to stress, such as DNA damage, nutrient deficiency and mechanical stress. Recently, the lamin family of cytoskeletal proteins have emerged as a key regulator of cell response to intrinsic and environmental stimuli. Lamins are the main architectural proteins of the nucleus and form a fibrous, highly stable meshwork underlying the inner nuclear membrane. The cell’s stress response triggers one of the lamin types, prelamin A, to accumulate, which affects important cellular processes such as cell cycle progression, DNA-replication, chromatin remodeling and senescence.

However, fundamental knowledge on the transmission of mechanical signals from cytosolic cytoskeletal protein networks to the lamina and lamin-dependent mechanism that allow for adaptation to mechanical is currently lacking. In this project, we aim to obtain fundamental understanding on the interplay and adaptation of various cytoskeletal proteins to convey mechanical stress to the nuclear content by investigating protein network structures in healthy and diseased cells. For this purpose, we aim to employ state-of-the-art 3D super-resolution microscopy and design novel quantitative data analysis pipe lines to enhance our understanding of pathogenic conditions underlying ageing and cancer.

We, the Geertsema lab, are an experimental biophysics lab employing super-resolution imaging techniques to improve understanding of cellular structures at the nanometer scale. As a recently started research group, we offer an interactive, supportive and collegial environment. We perform multidisciplinary research where we combine techniques from biophysics, microscopy, cell biology, biochemistry and protein engineering.

The Geertsema lab is embedded in the Imaging Physics Department of the TU Delft, which focusses on developing and implementing novel imaging technologies. The department features an inspiring, welcoming and pioneering environment for researchers that want to push the boundaries and implementation of current imaging systems.

Requirements
We are seeking an outstanding computational scientist with a strong interest in research at the interface of physics and biology. Research experience in fields such as biophysics, single-molecule techniques, optical microscopy, computational science or related is highly desired. We are looking for a team-player who can work independently and has a genuine interest in fundamental research.

Applicants must:

• Hold a Master’s degree, or approach its completion, in (bio)physics, biochemistry, engineering, nanoscience, or a closely related discipline
• Have excellent written and spoken English skills
• Thrive in an international and multidisciplinary team
• Affinity with super-resolution microscopy, Python and quantitative data analysis pipelines is a plus
