Biology, Bioinformatics, and Biotechnology:

Prof. Dr. Daniel Hoffmann (University of Duisburg-Essen)

Center of Medical Biotechnology

Bioinformatics and Computational Biophysics

Research Area:

The group develops probabilistic models for biological systems, e.g. B or T cell receptor repertoires of human immune systems, or HBV quasispecies, or a behavioral animal experiment, to give only a few examples. We then use experimental data, often from high-throughput sequencing experiments, and Bayesian inference to fit these models. From the posteriors we then (hopefully) learn important features of the modelled system.
For instance, we may learn in this way that specificities of T cell repertoires infiltrating a tumor may have characteristic features, or that viral quasispecies in patients with certain HLA alleles may escape immune responses in a certain way. In general our challenges are threefold: first, we have to understand the system of interest sufficiently to develop a meaningful model; second, we have to map reality onto a probabilistic model, which implies familiarity with the corresponding mathematical methods; third, we have to implement the models for efficient numerical inference, e.g. in the probabilistic programming language Stan.

Candidate Profile:

The perfect candidates should have a strong background in mathematics, computer science, bioinformatics, computational biology, statistics, or physics, including the ability to work with mathematical/probabilistic models and Bayes inference. Good programming skills are necessary. Programming practice in Stan, R, or Julia is advantageous, as is work experience with high-throughput sequencing data.
The perfect candidates should also be familiar with at least basic molecular biology, and they should have a strong interest to learn more about immunology and related areas of biomedicine.

Prof. Dr. Alexander Probst (University of Duisburg-Essen)

Environmental Microbiology & Biotechn.

Aquatic Microbial Ecology

Research Area:

The group for Aquatic Microbial Ecology focuses on understanding subsurface environments at the ecosystem level. Of particular interests are the recycling of microbial metabolites like lipids and proteins but the group also focuses on microbial interactions between different microbial species and also between viruses and microbes. For doing so, the group employes state-of-the-art meta'omics methods, for which genome-resolved metagenomics is the basis. At the same time, the group works on integrating genomic information in vizualizing uncultivated microbes and viruses in ecosystems.
As model ecosystems, we use cold-water geysers that are driven by carbon dioxoide degassing from the mantel. These ecosystems are highly active, show relatively high cell numbers and their carbon isotopic compositions and low organic carbon help to follow nutrient fluxes in the ecosystem.

Candidate Profile:

The group is looking for highly motivated postdocs in the field of microbial ecology with a strong background in bioinformatics.
While standard wet lab procedures (DNA and RNA extraction, simple microscopy) are sufficient, programming skills should exist as well. The ideal candidate is an advanced user on the command line interface (shell or bash programming) and has experience in python/ruby/perl scripting. Knowledge in R, maintenance of github site, and geology is a plus but not a necessity.
Interest in deep subsurface microbiology and aquifers is desirable. Ideally, the postdoc has experience in resolving genomes from the environment or has performed other genomic work in the past like comparative genomics.

Jun.-Prof. Dr. Andreas Reiner (Ruhr-Universität Bochum)

Cellular Neurobiology

Optical Control and Probing of Synaptic Signaling Proteins

Research Area:

We use novel, optical approaches to study membrane proteins, in particular to understand how protein complexes assemble and transmit signals across cell membranes.
Our main focus is on glutamate receptor signaling. Glutamate receptors (GluRs) play a key role in the central nervous system, where they pass excitatory signals across synapses and modulate synaptic strength and plasticity.
We combine biochemical methods, spectroscopic techniques, live cell imaging and electrophysiology to gain further insight into GluR function and physiology. As part of our toolset we use chemical photoswitches to manipulate GluRs with light – a method that allows for the precise control of specific receptor complexes with high spatial and temporal precision. At the same time, the engineering of photo-controllable ion channels and GPCRs provides a powerful tool for optogenetic and pharmacological studies.

Candidate Profile:

We are looking forward to host a motivated and independently working scientist, who is interested in exploring projects in the areas of chemical biology, cellular signaling, optogenetics, or neurophysiology.
Required is an excellent university degree in Biology, Biochemistry, Chemistry, or a related discipline, as well as a very high motivation to engage in interdisciplinary research and the ability to work in a team. Experience in experimental research and very good English skills are mandatory.

Prof. Dr. Lukas Gooßen (Ruhr-Universität Bochum)

Organic Chemistry I

Research Area:

Our research is devoted to the development of straightforward transition metal-catalyzed reactions as alternatives to inconvenient and hazardous multistep transformations. We are particularly interested in defining new strategies for the minimization of waste produced within a synthetic sequence. We have ongoing projects centering on the utilization of unusual substrate classes for catalytic cross-couplings with a focus on renewables, and on the development of regio- and stereoselective catalytic C-H or C-C bond functionalizations.
Our methodical work is supported by mechanistic investigations and quantum mechanical calculations, and complemented by organic syntheses that allow verifying the practical applicability of the new processes in the preparation of complex molecules such as pharmaceuticals.

Candidate Profile:

We are always interested in applications by highly motivated coworkers.
If you

  • love chemistry as much as we do
  • want to do exciting but sometimes difficult research
  • are a skillful organic chemist full of new ideas
  • speak both German and English
  • are not afraid of computers
  • feel the desire to go beyond the well-paved paths of organic synthesis

you might be just the right person for us.

Prof. Dr. Thomas Günther-Pomorski (Ruhr-Universität Bochum)

Molecular Biochemistry

Research Area:

A fundamental feature of eukaryotic cells is their compartmentalization into distinct organelles by biological membranes. Each membrane is composed of thousands of interacting lipids and proteins that are essential to basic processes from photosynthesis to the maintenance of electrochemical gradients across membranes. Many membrane proteins, including pumps and transporters, form multimeric complexes that can vary and adapt to the functional state of the cell.
We are interested in revealing organization, functioning and dynamics of membrane transporters and their complexes with special focus on lipid flippases. To this end, we have developed a variety of biochemical, biophysical and microscopic techniques including the synthesis of specific lipid probes for characterizing membrane properties, protein-membrane interactions and lipid trafficking in fungi, parasites and mammalian cells. Detailed insight into the molecular functioning of membrane pumps will help to understand vital processes at cellular membranes and pave the way for applications within synthetic biology such as personal medicine, sustainable energy production, and molecular bioelectronics.

Candidate Profile:

We would like to support candidates who have or will soon complete a doctoral degree in cell biology, molecular biology, biochemistry, biophysics or related areas and are interested to work on lipid transporters. Competence in molecular techniques, protein biochemistry or cell biology are important. A strong expertise in protein purification and reconstitution would be a further asset. Additionally, we are seeking for candidates with a strong expertise in Leishmania parasite cell culture and biology or confocal microscopy techniques (FRET, FLIM). We expect very good English skills, team spirit and the ability of working independently.

Inorganic Chemistry

Work Group Prof. Dr. Stephan Schulz

Research Area:

Research Area 1: Thin film deposition by metalorganic chemical vapor deposition (MOCVD), atomic layer deposition (ALD) and physical vapor deposition (PVD). We are concentrating on metal oxides (spinels) and different thermoelectric materials, mainly tetradymites (Bi2Te3, Sb2Te3, ...)

Research Area 2: Synthesis of metal organic complexes for ring opening polymerization (ROP) of cyclic esters, i.e. lactide, and co-polymerization.

Mathematics:

Prof. Dr. Gerhard Röhrle (Ruhr-Universität Bochum)

Algebra and Number Theory

Research Area:

This research group is involved with combinatorial, algebraic and geometric aspects of hyperplane arrangements. The theory of hyperplane arrangements has been a driving force in mathematics over many decades. It naturally lies at the crossroads of algebra, combinatorics, algebraic geometry and topology. Deep and remarkable connections have been discovered over the years between the geometry of the complement of an arrangement, the freeness of the module of derivations and the combinatorics of the intersection lattice of the arrangement consisting of the subspaces arising as intersections of hyperplanes from the arrangement.
Much of the motivation for the study of arrangements of hyperplanes comes from Coxeter arrangements. They consist of the reflecting hyperplanes associated with the reflections of the underlying Coxeter group.
In our research group we study various aspects of subarrangements and restrictions of arbitrary reflection arrangements.

Candidate Profile:

The candidate should have a solid background either in the theory of Coxeter or reflection groups or in the theory of hyperplane arrangements (or both). Knowledge in computational algebra and experience in computing with SAGE and GAP would also be an advantage.

Medicine:

Prof. Dr. Dr. Jürgen C. Becker (University of Duisburg-Essen)

Dermatology

Translational Cancer Research

Research Area:

Recent advances in cancer biology, molecular biology and immunology should allow for a significant impact on the treatment and management of cancer. Still, our knowledge of many fundamental aspects of biology in health and disease is insufficiently translated into the clinical situation to reliably improve cancer prevention and treatment; moreover, substantial parts of this knowledge were acquired by use of model systems, which are not always reflecting the clinical situation. Translational cancer research bridges the gap between laboratory-based science and patient care in the clinic and vice versa.
To this end, research in skin cancer permits to scrutinize tumor biology and cancer immunology with more ease than this is possible in other cancer entities: In skin, most tumors are diagnosed at early stages, are characterized by a progression in stages (i.e. loco-regional metastases preceding distant metastases), and the metastases are frequently localized in the skin. Thus, sequential tumor manifestations can be analyzed over the course of disease progression as well as during therapeutic interventions. These characteristics are extremely favorable for translational research strategies.

Candidate Profile:

We are looking for a highly motivated person interested in translational and multidisciplinary research in the field of dermatooncology. Preference will be given to applicants with previous experience in one or more of the following disciplines/areas of research: cancer biology, tumor immunology, systems biology, bioinformatics data analysis/statistics and/or imaging techniques.
The successful candidate should hold a master and PhD in life sciences, bio-medicine, biology or similar scientific fields and should possess a solid research background in molecular and cellular biology.

Prof. Dr. Sven Brandau (University of Duisburg-Essen)

Department of Otorhinolaryngology

ETN Research

Research Area:

Founded in 2007 we have since become a leading place for experimental research in head and neck oncology as well as cell biology not only in Germany but world-wide. We have a special interest in the immunological tumor-host interaction with a particular focus on neutrophils and myeloid-derived suppressor cells. A second research theme of the division aims at better understanding the immunoregulatory properties of so-called mesenchymal stromal cells. Over the last ten years we have established and worked on the following three main research themes:

Immunregulatory mechanisms in tumor-host interaction:
In spite of the potential recognition of malignant cells by the immune system and a resulting anti-tumor immune response, this reaction is mostly insufficient and subclinical. This is mainly caused by tumour-induced immune regulatory and immune suppressive mechanisms. In the last years, a variety of these mechanisms have been identified. Head and neck cancer (HNC) is also characterized by a particular immunosuppressive cancer-related inflammation. Thus, a better understanding of the reciprocal interaction of tumour tissue and host immunity forms the basis for identification of new therapeutic possibilities for intervention in HNC and other tumor entities.

Imunological and biological tumor therapy:
Even in the absence of classical tumor antigens, tumors harbor molecular structures, which can be used as targets for immunological or biological therapy. We are researching the effects of therapeutic antibodies directed against established (such as EGFR) or newly identified (collaboration R. Zeidler, Munich) target proteins on cancer cells. These antibodies may either directly inhibit the target protein or induce activation of immune cells. In addition we exploit the use of immunostimulatory toll-like receptor agonists to either stimulate immunity or induce cell death in tumor cells. Finally we are looking into differences of HPV+ versus HPV- HNC as well as the potential of HPV to serve as a target for immunological cancer therapy.

Immunobiology of mesenchymal stromal cells:
Mesenchymal stromal cells (MSCs) are fibroblastoid progenitor cells with multi-lineage differentiation potential. Next to their tissue regenerative properties, MSC also display strong immunoregulatory potential. We are interested in understanding the immunobiology of MSCs from the bone-marrow and from different tissues of the head and neck region. In particular, we are investigating their interaction with innate and adaptive immune cells, their response to immunological stimulation as well as their role in the tumor microenvironment.

Candidate Profile:

We are seeking a candidate with a PhD or/and a completed academic degree in the natural sciences or life sciences (Master or Diploma) and experience in the fields of cell biology, molecular biology or immunology. Solid scientific English skills are required. Pure basic research does not satisfy you. You are looking for a clinical environment and a disease-orientated research project. You are willing to work independently and apply your knowledge to a new area of research. Previous experience with cell culture, immunology and flow cytometry is beneficial. Interdisciplinary activity and collaboration will be required.

Prof. Dr. Nicole Dünker (University of Duisburg-Essen)

Department of Neuroanatomy

Retinoblastoma Research Group Prof. Dünker

Research Area:

We are interested in factors influencing the etiology and progression of retinoblastoma (RB), the most common primary intraocular tumor in childhood. Treatment of RB ranges from enucleation to eye salvage strategies including laser-, cryo-, brachy- and chemotherapy. Chemotherapeutic treatment of RB is, however, limited by developing drug resistances. Recent studies by our group suggest that trefoil factor family peptides might be potential new candidates for supplementary therapeutic options for RB along with common chemotherapy.
We are also investigating the mechanisms underlying chemoresistance. By transient and lentiviral overexpression and knockdown experiments followed by cell viability, cell death and colony formation assays we analyze the anti-oncogenic potential of identified candidate genes. In CAM assays we concomitantly pre-screen promising candidate genes for future RB treatment strategies for their capability to decrease tumor size and invasion capacity.
Most recently, we make use of nanoparticle-mediated substance delivery as well as nanoparticle-mediated gene knockdown and plan to also implement AAVs as an applicable RB treatment strategy.

Candidate Profile:

We are looking for highly motivated young researchers with team player qualities. Candidates should have profound experience in cell culture as well as broad knowledge in standard molecular biology methods like cloning, transfections, Real-time PCR and luciferase assays. Ideally, applicants already performed cell death and cell proliferation assays and FACS cell cycle analyses and are willing to perform in ovo CAM assays. It would also be ideal if the candidates already had experience with nanoparticles, AVVs and or CRISPR/CAS (as an alternate gene knockdown strategy) and would be willing to establish one or more of these techniques in our lab.

Research Area:

ABERRANT PROTEIN FOLDING AND NEURODEGENERATION

Various approaches coming from neuropathology, genetics, animal modeling and biophysics have established a crucial role of protein misfolding in the pathogenic process of different neurodegenerative diseases, such as Alzheimer's disease, Parkinson’s disease, polyglutamine expansion diseases and prion diseases. However, there is an ongoing debate about the nature of the harmful proteinaceous species and how toxic conformers selectively damage neuronal populations.

The main aim of our biochemical research is to identify cellular factors and signaling cascades implicated in neuronal integrity and in the pathophysiological alterations leading to neurodegeneration. Our integrative research has a strong focus on the biochemical and cell biological analysis of cellular pathways, which are also of broad neurobiological interest. Specifically, we are employing in vitro, yeast, neuronal cell culture and animal models to focus on three major topics:

  • Cellular mechanisms underlying the formation and toxic activity of aberrant protein conformers
  • Signaling pathways induced by neurotoxic conformers
  • Therapeutic strategies for neurodegenerative diseases

Candidate Profile:

We invite highly motivated candidates who would like to combine in vitro with cell culture assays and use super-resolution microscopy techniques (https://www.ruhr-uni-bochum.de/biochem/zellbio/imaging.html.en). Candidates should have a PhD in chemistry, biology, biochemistry, pharmacy or related fields and a strong background in biophysics, biochemistry and/or cell biology. Experience with protein expression and cell culture models is advantageous.

Department of Medical Ethics and History of Medicine

Ethics in Psychiatry

Research Area:

The research group “Ethics in Psychiatry” is a collaborative enterprise of the Institute for Medical Ethics and History of Medicine and the Department of Psychiatry, Psychotherapy and Preventive Medicine at the LWL University Clinic of the Ruhr University Bochum.
The treatment of persons with mental disorders raises a variety of ethical issues. For more than 20 years, our research group has conducted research on questions of patient autonomy, informed consent and decision-making capacity.

Mental health professionals and policymakers often raise the following questions:

  • What are the criteria for patient competence and how can competence be adequately assessed?
  • How can the autonomy of psychiatric service users be strengthened?
  • Under which conditions, if any, is it ethically justifiable to apply coercive measures?
  • By which methods can the use of coercion in psychiatry be reduced and are these methods ethically justifiable?
  • What are the specific ethical issues of end-of-life decision-making in patients with mental disorders?

We are an interdisciplinary group of researchers and we attempt to answer these questions by means of empirically informed ethical analysis. With backgrounds in psychiatry, psychology, philosophy and the empirical social sciences, we combine analytic skills with a thorough knowledge of the methods of quantitative and qualitative empirical research. Besides gaining knowledge, our aim is to provide mental health professionals with guidelines for ethical decision-making and to give practical recommendations for the improvement of psychiatric care.

Candidate Profile:

We are looking for talented and dedicated scholars with strong intellectual abilities, an interest in interdisciplinary research, flexibility, team-working skills, and a very good command of the English language. Candidates should have successfully completed a doctoral degree in medicine, philosophy, social sciences, psychology, or another relevant discipline with experience in the field of medical ethics.

Physics and Astronomy:

Prof. Dr. Ralf-Jürgen Dettmar (Ruhr-Universität Bochum)

Astronomical Institute

Chair of Astronomy

Research Area:

The intrinsic evolution of galaxies is driven by the physical conditions of the interstellar medium (ISM) since this determines the rate and distribution of star formation. In this context the energy and momentum feedback of the star formation processes on the ISM is as important as the supply of pristine gas from the outside.
The research in the group is structured around several observing programs addressing this general scheme. The approach is to use multiwavelength observations from X-rays to the radio to study the various phases of the ISM in the circumgalactic medium. A current focus is on radioastronomical techniques allowing, e.g., the detection of HI gas with its potential for kinematical information or radiocontinuum studies that provide information of cosmic ray electron transport mechanisms.

Candidate Profile:

The candidate has an interest in studying galaxy evolution through detailed observations of objects in the local universe and wants to put this into the context of structure formation. A good knowledge of radioastronomical techniques incl. the relevant software packages is a helpful prerequisite.
