Denmark : PhD position in multiphoton polymerization of immune cell scaffolds


Immune cells in the human body navigate in a soft microstructured 3D environment that has so far been difficult to mimic outside the body. In this project, you will overcome this technological barrier to efficient cell immunotherapy by using state-of-the-art multiphoton photopolymerization to microstructure hydrogel scaffolds in 3D.

Proper navigation of immune cells in the human body is essential for a range of new medical treatments termed immunotherapy. Present understanding of immune cell navigation in the soft 3D microenvironment of human tissue is limited due to lack of accurate tissue models. The goal of this project is to produce advanced technology and methods for evaluating immune cell navigation to improve clinical outcomes in immunotherapy. The project is part of a recently started research program on Microshaping hydrogels and their chemistry in 3D for optimizing and validating immune cell migration” in collaboration with clinicians at Herlev Hospital.

You will make use of the newest developments in multi-photon photopolymerization (
www.nanoscribe.de)to reproduce the 3D microscopic structure of human soft tissue in water-containing polymeric hydrogels. The structured hydrogels will be used as scaffolds for immune cell migration analysis, after being chemically surface modified to present concentration gradients of the signaling biomolecules that guide immune cells in the body.

You will work on design, fabrication, and characterization of 3D hydrogels with incorporated signaling molecules. The project will be carried out in close collaboration with colleagues having strong cell biological backgrounds, who will assist in the cell-based assays to evaluate the functionality of the hydrogels. Prior experience in cell biology is not a requirement. You will also be responsible for producing simpler microstructured hydrogels by conventional casting against microstructured dies. Thus, the work tasks will also include conventional clean room work to produce the required die structures by photolithography.

The position will be part of the Polymer Microtechnology for Cell Processing group at DTU Nanotech headed by Professor Niels B. Larsen. We are a group of young enthusiastic individuals focusing on generation of highly controlled microenvironments for culture, manipulation and analysis of sensitive human cells. The state-of-the-art polymer microfabrication activities are complemented by cell and molecular biology competences as well as general skills within automated time-lapse microscopy analysis of cell behavior. The multidisciplinary nature of the group, including people with backgrounds in physics, chemistry, nanotechnology, biochemistry, and cell biology, is ideal for the cross-disciplinary activities of this project.
QualificationsCandidates should preferably have a master's degree in chemistry, microtechnology, or engineering sciences, or a similar degree with an academic level equivalent to the master's degree.

Denmark : PhD scholarship in Naval Architecture


A PhD scholarship is available at DTU Mechanical Engineering in the field of Tools for design and operation of Ultra Large Container Ships. The department has well-established research programs in naval architecture and the present scholarship is partly funded by an on-going EU project.

Project description
Effective on-board decision systems for guiding the ship through harsh weather require accurate knowledge of the actual sea condition. This has been identify in the on-going EU-FP7 project Tools for Ultra Large Container Ships (Grant agreement no.: 234146) as a crucial point:

“Finally, it is important to mention the difficulties related to the full scale measurements and their interpretation. While the direct measurements of the ship response in terms of the structural strains, ship motions and accelerations are well mastered today, this is not true for the measurements of the local pressures and especially for the measurements of the sea states in which the ships are navigating. The most common wave radar based systems suffers from several technical difficulties and associated uncertainties. The most advanced wave measuring system will be used within this project and their implementation will be improved.”

The aim of the present project is to develop and implement an improved sea state estimation procedure. The following topics have been identified as most important:
  • Dynamic selection of ship responses to be used in the sea state
  • Check for faulty signals
  • Inclusion of fatigue damage estimations in the operational criteria
  • Power prediction estimates based on semi-empirical formulas and proper estimation of added resistance in waves
The project should results in an on-board software system able to run real time on a standard PC and using input from standard sensors like accelerometers and strain-gauges.

The expected starting date is 1 August 2010.
QualificationsCandidates should have a master's degree in engineering or a similar degree with an academic level equivalent to the master's degree in engineering. Strong skills in naval architecture, ocean engineering and programming in C/C++/Fortran/Matlab are required, as well as a keen interest in software development and decision support systems.

Approval and Enrolment
The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the 
DTU PhD Guidefont.

Salary and appointment terms
The salary and appointment terms are consistent with the current rules for PhD degree students. The period of employment is 3 years.

Denmark : PhD position-NANOVATION-Innovative industrial exploitation of nanotechnology


An international research project is being established in collaboration between the Department of Micro and Nanotechnology (DTU Nanotech) and partners within industry as well as academia. The aim of the PhD position is to develop systematic methodologies for shape optimization of nanostructured surfaces, to characterize and compare different structuring approaches in terms of performance and industrial relevance, and finally explore the possibilities for application in collaboration with Danish companies.

Industrial areas as diverse as medical equipment, food processing and packaging, high-end audio systems, miniaturized microphones and hearing aids, kitchen utensils, silverware and cell phones, all share a common property: the surface of the products get in touch with organic material that interferes with its function. Nanostructured surfaces are a relatively new approach to enhance the anti-reflective, anti-sticktion, self-cleaning and anti-bacterial properties. Recently, attention is given to the detailed geometrical shape of the surface as a route towards extreme water and oil repellence.

Within the last years it has been possible to optimize the geometrical structure of complex non-linear systems using algorithmic methods - topology optimisation. This has been applied with astounding success within the fields of structural mechanics, photonics, microfluidics and chemical reactors, but has so far not been demonstrated within the field of nanostructured surfaces. We aim to develop a library of generic designs that enhance the contact properties and are applicable within many new research fields of industrial relevance. Part of the project will concern improvement of the topology optimisation to incorporate surface-effects well enough, which will be of great importance within the optimization-community and for the industry.

Research Plan
  • Initial investigation of simplified model-systems to gain fundamental insight
  • Improve topology optimization methods for better incorporating surface effects
  • Further develop level-set based topology optimization methods
  • Apply level-set methods for optimizing surface effects
  • Apply the methods to design actual surface structures with optimized surface functionality
  • Fine-tune optimal design through shape-optimization
  • Include fabrication constraints
  • Realise theoretical structures using state-of-art fabrication techniques such as high resolution electron beam lithograph and 2-photon photopolymerisation
  • Feasibility study in terms of scaling up to industrially relevant volumes
The tasks will be carried out in the Theoretical MicroSystems Optimization Group (TMSO) at DTU Nanotech, in close collaboration with the Nanointegration group at DTU Nanotech as well as Laser Zentrum Hannover, Danish Technological Institute and a number of Danish companies. The Innovation Consortium is funded by The Danish Agency for Science, Technology and Innovation.
QualificationsThe successful candidate, who must have a master's degree and a good background in mathematical physics, is expected to work theoretically and numerically on optimizing the energy systems involved in the project. This involves in parti cu lar modelling of complex surface-fluid interfaces. The ideal can di date has a strong background in microfluidics theory and simulation, and knowledge of optimization theory will be preferable. As the project also involves experimental realisation and characterisation of nanostructured surfaces, some experience with experimental and/or fabrication work will be highly beneficial. Good communication skills and a wish to engage in a lively collaboration are also required, as frequent interaction with academic as well as industrial partners is anticipated.

Approval and Enrolment
The PhD scholarship is subject to academic approval and the candidate will be enrol led in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the PhD studies, please see the

Denmark : PhD scholarship in Adaptive Simulations of Nonlinear Structures in Magnetized Plasma


DTU would like to invite applications for a 3-year PhD position starting as soon as possible; no later than October 1, 2010.
Project description
Three departments at DTU would like to invite applications for a joint PhD position in scientific computing and plasma physics. The project initiates a unique collaboration among the Scientific Computing section at DTU Informatics, DTU Mathematics, and the Plasma Physics group at Risø DTU. The PhD student will conduct research in advanced numerical methods for high-performance computations of magnetised plasma in fusion power devices. This collaborative effort reflects the need for a multi-disciplinary approach towards mathematical modelling of complex physical processes, which requires a strong interplay between physics, scientific computing, and mathematics.

In plasmas, self-organisation processes result in coherent structures forming out of turbulence if the dynamics is mainly two-dimensional. In magnetised plasmas this happens due to the strong anisotropy in the dynamics parallel and perpendicular to the magnetic field. Fusion machine (tokamak) operation is hindered by the occurrence of such structures, bringing with them expulsions of energy dangerous to the integrity of the material surfaces facing the hot plasma. Since the dynamics of such events involves physical effects occurring at very different spatial and temporal scales even the computational power of the fastest supercomputers available today is insufficient for straightforward first principles simulations. Only by utilizing the special geometric structure of the problem in conjunction with high-performance computing can we hope to model such complex systems.

The PhD project will be devoted to finding, developing, and testing strategies towards solving this problem. The focus will be on the use of advanced numerical methods which support spatial and temporal adaptivity for resolving local features in complex three-dimensional geometries. The student will have an opportunity to conduct research in high-order accurate schemes and scalable parallel algorithms for efficient solution of the relevant prototype problems. The project includes the possibility of interaction with the international fusion research effort. 

Qualifications 
Candidates should have a master´s degree in engineering, physics or applied mathematics. She/he should have a strong background and interest in mathematics and/or physics and be able to document skills in scientific computing. Furthermore, good command of the English language is essential. 

Approval and Enrolment
