PhD Positions, Göttingen Graduate School for Neurosciences and Molecular Biosciences, Germany

The Göttingen Graduate School for Neurosciences and Molecular Biosciences (GGNB) was founded in 2007 as a joint enterprise between the University of Göttingen, three Max Planck Institutes, and the German Primate Center. GGNB is funded by the Excellence Initiative of the German federal and state governments.
Ten doctoral programs are currently united under the roof of GGNB, sharing a common interdisciplinary training platform for their Ph.D. candidates. All courses are in English. Each Ph.D. candidate is affiliated with one of the doctoral programs of GGNB where he/she receives individual counseling and is guided in his/her thesis work by a thesis committee of at least three faculty members. We invite for applications for Ph.D. positions in Biology / Physics / Chemistry in the following doctoral programs:
• Biomolecules: Structure – Function – Dynamics
• Molecular Biology of Microbial, Animal and Plant Cells
• Molecular Biology of Development and Interaction between Organisms
• International Max Planck Research School “Physics of Biological and Complex Systems”
• Molecular Physiology of the Brain
• Sensory and Motor Neuroscience
• Systems Neuroscience
• Theoretical and Computational Neuroscience

Scholarships and institutionally financed Ph.D. positions are available.

Candidates holding a Master’s degree in the natural sciences or related disciplines and an excellent academic record may apply by 15 September 2010 or also independent of deadlines. See www.ggnb.uni-goettingen.de for details.

PhD-Position, ‘Numerical flow Simulation of Atmospheric Nocturnal Wind Bursts’, Netherlands

The Department of Applied Physics at Eindhoven University of Technology has 15 professorial chairs with about 65 academic and 60 technical specialists, as well as 110 graduate and 375 undergraduate students. The leading research themes cover functional materials, transport physics, and plasma physics and radiation technology. The department has extensive national and international partnerships, including industrial partners. It participates in several national (top) research schools, and in two national top technology institutes: Dutch Polymer Institute (DPI) and Materials Innovation Institute (M2i). Eindhoven University of Technology is one of the three participants in the Dutch 3TU Federation of Universities of Technology.

The project aims to solve a long-standing problem in boundary layer meteorology: to find the physical mechanism that drives intermittent (discontinuous) turbulence in the atmospheric nocturnal boundary layer. During intermittency, periods with ‘laminar’ flow are interrupted by chaotic bursts of turbulence and a significant transport of heat, moisture and momentum occurs. Bursts also act as an efficient ‘venting’-mechanism of pollutants that usually accumulate in quiet periods. The problem is highly relevant in weather and climate prediction and for air pollution problems. Current nocturnal boundary layer parameterizations are highly empirical and lead to significant errors in weather and climate predictions, especially in arctic regions.

The candidate will perform numerical simulations of stably stratified channel flows (with a Direct Numerical Simulation model). Different numerical experiments will be set up. The aim is to start with simplified studies and then increase the complexity of the simulations as to mimic atmospheric flows. Thus we start from non-interactive surface boundary conditions towards simulations that mimic (rudimentary) atmosphere-vegetation interactions. The outcome of the simulations will be used to develop a theoretical framework to predict this intermittence character of turbulence (using hydrodynamic stability analysis). Finally, results will be compared with readily available observations that were obtained in the outside atmospheric nocturnal boundary layer.

Requirements recent or impending MSc-degree in Physics, Mathematics, Meteorology or Mechanical Engineering with a special focus on fluid mechanical topics. Experience with numerical flow simulation (LES, or DNS) is a clear advantage. Finally, the candidate should have some interest in geophysical flows and be willing to follow courses on this topic if necessary.

PhD Researcher: The Uncertainty Enabled Model Web, Netherland

The Department offers a BSc in Building Science (Bouwkunde) and MSc programmes in Architecture, Building and Planning, Building Services and Construction Management and Engineering. Research is design and application oriented, based on fundamental scientific insights and methods. The project is funded by the 7th Framework Programme of the European Commission Theme FP7-ICT-2009-4: ICT for Environmental Services and Climate Change Adaptation. The DDSS research program has about 30 scientific staff (including 15 PhD researchers) of different disciplinary background from across the world. Project description: The project is part of the program UncertWeb. This project will implement an application to model activity-travel patterns of people in a city to demonstrate service chaining in the presence of uncertainty. In particular, the focus will be on a chain of models linking land-use change (or other policies) to changes in activity-travel patterns of individuals, which in turn will be linked to emission and exposure models. All these models involve uncertainties in terms of data and in the various models. The uncertainty-enabled model Web will be used to trace the propagation of uncertainty through this series of linked models. The core model is Albatross, a detailed model that has been developed by TUE for simulating how individuals use the environment. Albatross was developed for the Dutch Ministry of Transport and simulates activity-travel patterns of individuals in time and space at high resolution. Target variables include variables that are relevant from an air quality modelling perspective: the number of persons exposed to high air pollutant levels, classified by individual characteristics (gender, working/non-working, age) and activities (sporting, non-sporting) for a given area and a period of time, and variables that can be used as air quality model inputs: the number, speed and type of cars as a function of area and time. Time-activity simulations take place by representing the behaviour of a part of the population by agents in the computer, where this part is large enough to reflect variability in the population. The representation is used to predict time-activity patterns, and derived characteristics such as traffic congestion. Uncertainty in such predictions arrive from (a) limits due to limited representation of the target population, (b) limits due to incomplete and approximate modelling of behavioural decisions, and (c) when the model is used in predictive mode, from uncertainty in external factors in decision making, such as short-term weather conditions. Profile of the candidate: The candidate should possess a master degree and a good background in research methods, statistical analyses and computer programming. Further requirements: – Demonstrated interest in scientific research – Proficiency in English writing and speaking – Highly motivated to conduct academic research – Team spirit Salary: The duration of the project is for 3 years. The gross monthly salary increases from 2.042, – Euro in the first year to 2.492, – Euro in the third year. In addition, the TU/e has an excellent package of attractive benefits for employees, a child-care facility, and a modern sports complex. Assistance for finding accommodation can be given.
