Postdoctoral Position in “Tissue Integrity of the Intervertebral Disc”, Netherlands

The Department of Biomedical Engineering is a joint department of the Eindhoven University of Technology and the University of Maastricht interfacing and integrating engineering and biomedical sciences from the two universities. The department is organized into 4 divisions: 1) molecular bioengineering, 2) biomechanics and tissue engineering, 3) biomedical imaging and informatics, and 4) biosignals and regulation.

In the second division is the Orthopedic Biomechanics Section whose general objective is to improve our understanding of function and damage of orthopedic tissues, esp. bone, cartilage and intervertebral disc. Ultimately, these insights are used to develop and improve strategies for treatment of pathologies. For this purpose, we regularly combine experimental and computational approaches. Results from experimental studies on cells and/or tissues are captured in theories that are evaluated using computer models, and predictions by these models are helpful for the design and interpretation of further experiments.

Project description:

Degeneration of the intervertebral disc is a common, painful and disabling pathology whose etiology and pathogenetic mechanism is poorly understood. It is generally believed that genetic, cell nutrition and biomechanical factors play a key role; however the interactions between them have been difficult to investigate because of the inherent limitations of current cell and organ culture methods. Among the genetic factors, collagen IX polymorphisms have been identified as a risk factor. In this project, the role of collagen IX will be investigated on the nanoscopic level in collagen gels of chicken. Optical tweezers will be used to analyse the influence of collagen IX upon a collagen network down to the individual fibril level. The resulting finding will be built into an existing FE-model of the degenerating disc.

Postdoctoral Position in Homogeneous Catalysis, Netherlands

The Department of Chemical Engineering and Chemistry (ST) is one of the nine departments of Eindhoven University of Technology (TU/e). It was established in 1957. The department has approximately 500 employees (411 fte), 16 full professors, 370 undergraduate students (bachelor and masterstudents) and about 170 graduate students (140 Ph.D. and 30 design engineers).The department aspires to be an academic institution for education and research in chemical science and engineering that meets the highest international standards. The aim is to generate and to develop technology and scientific knowledge relevant for the long-term needs of society. Scientific curiosity and the use of newly generated knowledge are the main driving forces for the continuing enhancements of the three chosen fields of expertise: molecular, materials, and process engineering.

The Homogeneous Catalysis Group
The homogeneous catalysis group offers a dynamic international research environment. Research activities span a wide range from fundamental questions to application oriented research. In an integrated approach we are interested in the development of efficient and sustainable catalytic conversions. In mechanistic studies we strive for a deep under­standing of chemo-, regio-, and stereoselective processes on the molecular level, employing (in situ) spectroscopic methods and kinetic studies. Ligand and catalyst design, synthesis, and characterization are an important part in this process. This fundamental insight and knowledge is employed to develop new catalytic conversions and to improve existing routes towards more sustainable processes (e.g. feed-stock diversification and renewables). Catalyst testing and reaction optimization is strongly supported by state of the art automated and parallel testing facilities. For the applicability of homogenous catalysts, separation and recycling are key issues. We aim at the development of generic methods for catalyst immobilization and compartmentalization, towards continuous operation, employing two-phase catalysis and membrane separation techniques. Typically in this field catalyst development and reaction/reactor engineering go hand in hand. Actual projects span from fine chemical applications like asymmetric catalysis for fragrances and pharmaceuticals to large scale intermediates like amines and aldehydes for the polymer, detergent and lubricant sector. Of course this broad range of activities has led to numerous international cooperations with academic and industrial partners. We are actively participating in a range of European research networks and initiatives.

Project
The project is part of a European Research and Training Network (ITN-NanoHost; http://www.nanohost.eu/) within FP7 deadling with homogeneous catalyst immobilization and recycling in the context of process intensification. The project, NanoHost, “Homogeneous Supported Catalyst Technologies: the sustainable approach to highly-selective, fine chemicals production” is a joint effort of 7 partners and 3 associated partners.
The candidate will focus on the synthesis and application of nanostructured organic/inorganic hybrid materials for molecular weight enlarged catalysts (MWE catalysts) in a homogeneous catalytic reaction of industrial relevance. MWE catalysts will be prepared, characterized, and applied in continuously operated reactors equipped with a membrane filtration unit for catalyst compartmentalization.
Relevant kinetic and thermodynamic data will be acquired in multi-batch and continuously operated reactor setups. Based on these initial studies an improved loop reactor unit will be designed, modelled, and built in a close cooperation with other partners.
State-of-the-art equipment and expertise for research in homogeneous catalysis and catalyst immobilization is present (HP-autoclaves, membrane filtration units, Schlenk lines, glove-box, analytical and preparative HPLC, (high pressure) NMR and IR spectroscopy, etc.). Training in a wide range of supplementary skills is offered by the host institution and by special training workshops and secondments arranged by the network.

Profile
We are looking for a talented and enthusiastic postdoc with a master degree in Chemistry or Chemical Engineering, with solid knowledge and practical skills in organic chemistry, organometallic chemistry or homogeneous catalysis. You also need to meet up the requirements for the eligibility of the researchers from Nanohost. You can look for more information: http://www.nanohost.eu. Applicants are expected to have excellent skills in preparative organic and organometallic chemistry and have good analytical and communicative skills. You are creative and think for yourself, fluent in English and you are a team player.

Appointment and Salary
We offer a challenging job at a dynamic and ambitious university. The gross monthly salary in accordance with the Collective Labor Agreement of the Dutch Universities (CAO NU) starts with € 2861,-.

Postdoctoral Position in Mechanical Screening and Selection of Circulating Cells, Netherlands

The Department of Biomedical Engineering is a cooperation of Eindhoven University of Technology (TU/e) and the Faculty of Health, Medicine and Life Sciences of the University of Maastricht. The department participates in distinguishing research programs. Research areas are Molecular Bioengineering & Molecular Imaging; Biomechanics & Tissue Engineering; and Biomedical Imaging & Modeling. TU/e is situated in the European technology hotspot ‘Brainport Eindhoven’, known for its many high-tech industries and start-ups. A sparkling environment with opportunities for talented people.

The Department of Mechanical Engineering considers as the core of their activities design, realization and analysis of new products, processes and materials. Besides the basis of (solid and fluid) mechanics, materials, control and thermodynamics, parts of mathematics, physics, chemistry and computing science are important supporting tools. The field is explored by a combination of modeling using fundamental concepts and applied engineering and technology. Automotive Engineering Science and Micro- amp; Nano-Scale Engineering are important departmental themes. The Mechanical Engineering Department comprises about 1000 students and 250 staff members.

Cell lysis is the process of disrupting a cell membrane in order to obtain intracellular material, such as DNA, RNA, proteins, organelles, mitochondria, chloroplasts, etc, for further analysis or use. This is therefore an essential step in many biological and biomedical applications, for example for the sequencing of DNA originating from prokaryotic and eukaryotic cells, or for infectious disease testing in which NA of bacteria or viruses must be detected. There are a number of existing lysis methods. Most of them use large volumes and are not suitable for integration in lab-on-chip systems. Methods using chemicals and /or enzymes to lyse cells could be miniaturized, but are considered to be too expensive or too invasive in disposable diagnostic systems. Our approach is to use the combination of electroporation (using electric fields generated by electrodes integrated in the device) with elongational flows to lyse cells in a controlled way within a micro-fluidic system. The advantage of this approach is that it may lead to a gentle, controlled lysis procedure. In addition, the approach would give the opportunity to study cell lysis in a controlled way in order to understand the process better.

The basic idea is that electroporation introduces controlled defects in the cell membrane, effectively weakening it. A subsequent exposure of the cell to an elongational flow would then deform it until complete lysis occurs. This process is reminiscent of classical fracture mechanics approaches.

The aim of the PostDoc project is to design variations of fluidic and electrode geometries to study the lysis method, in particular the effect of lysis on cell content, e.g. proteins or complexes of proteins. The device and the method need to be optimized to obtain a highly controllable method. The focus will be on circulating cells from the blood stream. Based on the experimental results, a model describing the cell failure has to be developed. This model will basically consist of the viscoelastic model for cell deformation, extended with a failure model. The combination of the numerical model and the experiments will lead to a better understanding and prediction of the effects of cell lysis. The project is embedded in a larger research program on ‘Circulating Cells’, performed by a consortium of several academic, clinical and industrial partners and funded by the Center for Translational Molecular Medicine (CTMM). The PostDoc will interact with these partners, and will be collaborating with existing activities on cell mechanical studies at the Materials Technology Institute.

Requirements

We are looking for candidates with a PhD in biomedical engineering, mechanical engineering, applied chemistry, etc. with a strong affinity for experimental and/or numerical micro-fluidic experiments, cell biology or mechanics, and biomedical applications.

Appointment and Salary

We offer:

* A challenging job at a dynamic and ambitious University
