Ph.D. position in characterization of dynamics of biological systems

Research project

Understanding biological function depends critically on characterization of the dynamics of the system. However, direct measurement and characterization of a system’s motion is not trivial; in most cases, a single experimental method may not provide enough information to separate different types of motion present in a system, making interpretation challenging.

Our recent work has focused on developing analytical methods that allow comparison of timescale-specific dynamic parameters between different methods, with the result being the so-called detector analysis.1 We have applied detectors to solid- and solution-state nuclear magnetic resonance (NMR) and to molecular dynamics simulation (MD) data, giving us the ability to perform quantitative, timescale-specific comparison of simulation to experiment. MD simulation quality can be then validated against NMR experiments, and NMR may be interpreted based on MD.

NMR-based dynamics characterization primarily reports on the influence of motion on local bond orientations, where measured data is the collective result of both local and long-range motion. Förster Resonance Energy Transfer (FRET), on the other hand, reports on distance modulation between two fluorescent tags. Such data more directly characterizes long-range motion, therefore providing valuable experimental information that is not easily extracted from NMR alone.

Then, the successful candidate will work on further development of the detector analysis, with a particular focus on its application to FRET, with a goal of combining FRET results with both NMR and MD analyses.
