Program Description:
Max Planck Institute for Dynamics and Self-Organization

Organization Overview
The Max Planck Institute for Dynamics and Self-Organization (MPIDS) belongs to the Max Planck Society. Its research focus is in physics, with strong interdisciplinary aspects. It emerged in 2004 from the Max Planck Institute for Fluid Dynamics. In 2011 it moved from the Bunsenstrasse in Göttingen to the Max Planck Campus at Fassberg, located between the main town of Göttingen and its suburb Nikolausberg. The MPIDS is now right next to the Max Planck Institute for Biophysical Chemistry, with which it already had and continues to have cooperations in interdisciplinary areas between physics, biology and medicine. There is also a close connection with the Faculty of Physics at the University of Göttingen.

Intern Responsibilities:

IIP interns will work on tasks related to the following experimental and theoretical projects at the Institute.

1. Control of pattern formation in Dictyostelium discoideum cells 
A classic example of self-generated patterns in nature is found in the social amobae Dictyostelium discoideum. When starved, millions of individual cells signal each other with the signaling molecule cyclic adenosine monophosphate (cAMP).  cAMP waves in the form of spiral or target patterns propagate in cell populations and direct aggregation of individual cells to form centimeter-scale Voronoi domains and eventually multicellular fruiting bodies. In this study, the institute controls the shape of Voronoi domains by introducing periodic geometrical obstacles with different size and periodicity in the system. The institute observes that the obstacles act as aggregation centers and the periodic arrangement of the obstacles is reflected directly in the corresponding Voronoi domains.  

Qualifications
bio-lab experience, familiar with programing


2. Thermal convection
Thermal convection is fluid flow driven by a thermal gradient. If the thermal driving is strong, the flow is turbulent. Such flows are one of the most efficient heat transport mechanisms and occurs in many industrial and natural systems. The institute investigates the heat transport and the fluid flow by thermal convection in cylindrical vessels with a hot bottom and a cold top plate. Most investigations assume Boussinesq conditions, which means that the fluid properties are the same at the warm bottom and the cold top plate. While studying such simplified systems is important for a fundamental understanding of the underlying mechanisms, in many industrial and natural convection systems, the Boussinesq conditions are not fulfilled. In example, for industrial cooling systems, super critical gases are used that have viscosities similar to gases but heat capacities of liquids. Other examples are atmospheric convection or convection in stellar interiors. In the project the IIP intern would study turbulent thermal convection at strongly non-Boussinesq conditions by using Sulfur-hexafluoride (SF6) above its critical point. The heat transport and the flow field are studied using thermal probes and optical techniques.

Qualifications: 
familiar with programing, data analysis skills, fluid mechanics


3. Chemotaxis
Chemotaxis, the directed motion of a cell toward a chemical source, plays a key role in many essential biological processes. The institute describes the directional motion as the interplay between deterministic and stochastic contributions based on Langevin equation. The functional form of this equation is directly extracted from experimental data by angle-resolved conditional averages. It contains quadratic deterministic damping and multiplicative noise. The IIP intern will use the institute's approach, which captures the dynamics of chemotactic cells, and will quantify differences and similarities of different  amoeba and characterize the heterogeneity within a population of migrating cells.

Qualifications: 
bio-lab experience, programming, microscopy

IIP candidates with interests in physics, biophysics, biology, math, and natural sciences are encouraged to apply. Prior lab experience would be an asset.
