PhD/Post-doc: Single Proteins at the Ribosome

Understanding protein biogenesis

Mekelweg, Delft, Zuid-Holland
Tijdelijk contract / Tijdelijke opdracht
Uren per week:
40 uur


Chaperones are central to protein biogenesis, but their action at the ribosome remains poorly understood. A central complication is the highly dynamic nature of this process, which involves polypeptide synthesis, folding, chaperone binding, and ATP cycles, as well as a possible interplay between chaperones. New tools now allow us to directly monitor these dynamics. Recently it has become possible to detect protein conformational changes mediated by chaperones, as we have shown at the single-molecule level using optical tweezers for SecB, Trigger Factor, and Hsp70 (Science 2007, Nature 2013, Nature 2016). The recent integration of single-molecule fluorescence now allows us to visualise the composition of actively translating ribosome-chaperone-client complexes, pushing the envelope of technical possibilities. In this project, we use this novel approach together with ribosomal profiling in order to unravel the first steps of protein biogenesis in real time.

The position is intended as a full-time appointment. The formal employment and main activities will take place at AMOLF in Amsterdam. The student will participate in the TU Delft graduate school, and the PhD degree will be granted at the TU Delft.    


We are looking for an outstanding experimental physicist or chemist with an interest in single-molecule biophysics and a strong drive to excel in a competitive, international environment. For a post-doctoral appointment you must have a PhD degree. Good communication skills in English are required.


The PhD position is intended as full-time (40 hrs/week, 12 months/year) appointment at AMOLF for the duration of four years; a post-doctoral appointment is for two years.
AMOLF assists any new post-doc with housing and visa applications and compensates their transport costs.
As a PhD candidate you will be enrolled in the TU Delft Graduate School. TU Delft Graduate School provides an inspiring research environment; an excellent team of supervisors, academic staff and a mentor; and a Doctoral Education Programme aimed at developing your transferable, discipline-related and research skills.
