About This PhD Project

Project Description

Group:
Prof. Matthias Rief, Molecular biophysics E22, Physics Department, TU Munich
Website: http://bio.ph.tum.de/home/e22-prof-dr-rief/rief-home.html

Project:
Single molecule methods allow to observe the conformational dynamics of individual molecules over extended time periods with subnm resolution. In our lab, we have developed high resolution optical tweezers that allow the manipulation of individual protein molecules. In this project, we like to combine single molecule mechanics with single molecule optical spectroscopy to observe force-induced binding events optically. In the first part, an existing optical tweezers setup will have to be modified and extended with single molecule fluorescence capability. In the second part of the project this setup will be used to study enzyme mechanics on the single molecule level.

Requirements:
Ideally, the successful candidate will have a background in experimental physics/biophysics or biochemistry and should not be afraid of an interdisciplinary project and environment. .

All candidates have to apply via CeNS’ online application tool. Other forms of application will not be accepted.
