Masterarbeit im Fachbereich Onkologie

[english below] Wir bieten ein spannendes Projekt an der Schnittstelle von Zellbiologie und Medizin im Bereich Pankreaskarzinomforschung an. Das duktale Adenokarzinom des Pankreas (PDAC) ist durch ein fibroblastenreiches desmoplastisches Stroma gekennzeichnet, dass eine kritische Rolle bei der Progression und Therapieresistenz des PDAC spielt. Dieses Projekt wird sich auf die Interaktion zwischen CAF (Tumor-assoziierte Fibroblasten) und PDAC-Zellen im humanen Zellkultursystem konzentrieren und aufklären, wie die CAFs die Aggressivität von PDAC-Zellen durch verschiedene Mechanismen fördert und neue Therapiekonzepte abgeleitet werden.

We offer an exciting project at the interface of cell biology and medicine in pancreatic cancer. Pancreatic ductal adenocarcinoma (PDAC) is characterized by a fibroblast-rich desmoplastic stroma which plays a critical role in the progression and therapeutic resistance of PDAC. The stroma is composed of extracellular matrix proteins, mainly deposited by the cancer-associated-fibroblasts (CAFs) and various types of immune cells. Cancer-associated fibroblasts display a high degree of interconvertible states including quiescent, inflammatory and myofibroblastic phenotypes. However, the mechanisms by which this plasticity is achieved are poorly understood.

This project will focus on the CAF – PDAC cell interaction in the human cell culture system and will elucidate how CAF plasticity promotes PDAC cell aggressiveness through multiple mechanism.

Our spectrum of methods we can offer

  • Cell culture
  • Working with primary human and murine cell lines (organoids)
  • Drug screens
  • Co-Culture systems
  • Manipulation of human und murine cell lines (CRISPR Cas9, etc.)
  • Broad spectrum of molecular biology (ELISA, Western Blot, PCR, Cloning of Plasmids)
  • Flow cytometry
  • Orthotopic Implantation (mouse models)
  • Imaging (MRT, PET)

Master Thesis NMR & Batteries

Interested to work on an interdisciplinary project at the interface of new NMR technologies and batteries?

Recent experiments have shown that defects in diamond can be used as quantum sensors for detecting NMR (nuclear magnetic resonance) signals from tiny volumes down to a single molecule!

This new technology will be used here for NMR spectroscopy to probe batteries in situ. In particular, we would like to monitor ion diffusion in batteries on the microscopic scale, which is of central importance for their function. Pulsed-field-gradient (PFG) NMR is a common method used for measuring atomic and molecular diffusion. However, it cannot detect low diffusion coefficients such as they occur in batteries due to limited available magnetic gradient strength7. In contrast, the microscopic NMR detection volume of NVs will allow the application of several orders of magnitude high magnetic field gradients over the sample volume. This will not only make it possible to measure very low diffusion coefficients but also to monitor unprecedented ultrashort diffusion length on the nanometer range. This will result in the determination of ion diffusion coefficients at interfaces, which cannot be obtained with current methods.

Tasks: Design and fabricate diamond sensor with integrated gradient coils for probing batteries.

Techniques: 3D-printing, electronics, NV-quantum sensing, NMR, chemistry

Skills: Ideally some knowledge of batteries and/or NMR spectroscopy.

Master Thesis NMR & Catalysis

Interest to work at an interdisciplinary project at the interface of new NMR technologies and chemistry/catalysis?

Recent experiments have shown that defects in diamond, in particular nitrogen-vacancy (NV) centers, can be used as quantum sensors for detecting nuclear magnetic resonance (NMR) signals from tiny volumes down to a single molecule!

NV-NMR is paving the way for high-sensitivity real-time monitoring of chemical reactions on surfaces at the nanoscale in a totally non-invasive and non-destructive way. A natural application of such a new tool is the study of heterogeneous photocatalytic systems, where light-driven reactions take place on the surface and where very often the formation of short-lived radical species is crucial for the functioning of the catalytic cycle.

In this interdisciplinary project at the interface of Quantum sensing, Electron Paramagnetic Resonance (EPR) spectroscopy, chemistry and catalysis you will use NV-shallow-implanted diamond chips as sensing platforms on which to perform photocatalytic reactions to be monitored in real-time at room temperature. For the purpose you will implement NV-based-relaxometry experiments based on laser/LED light excitation as well as on spin-manipulation by microwave fields. This will enable the measurement of the relaxation times of the NV-electron spins being perturbed by the interacting intermediates during the catalytic process. This will allow to get crucial insight on the overall heterogeneous catalysis mechanism at the nanoscale.

Tasks: Putting into operation an optimized setup for NV-based experiment

Techniques: NV-NMR, Chemistry.

Skills: Ideally knowledge of NMR/EPR spectroscopies, physical chemistry and spectroscopy, inorganic chemistry and catalysis.

Master Thesis NMR & Life Sciences

Interested to work on an interdisciplinary project at the interface of new NMR technologies and life science?

Recent experiments have shown that defects in diamond, in particular nitrogen-vacancy (NV) centers, can be used as quantum sensors for detecting nuclear magnetic resonance (NMR) signals from tiny volumes down to a single molecule!

NV-NMR is paving the way for NMR analysis on the single-cell level enabling us to study metabolites and metabolic states of single living cells in a non-invasive and non-destructive way. To achieve this highly ambitious goal and due to the inherently low sensitivity of NMR, we employ so-called hyperpolarization schemes resulting in an exceptional enhancement of the NMR signal. A promising technique for breaking the sensitivity limitations of NMR is hyperpolarization of nuclear spins by parahydrogen induced polarization (PHIP). In these schemes the transfer of the non-thermal singlet spin order of parahydrogen to the target substrate leads to several orders of magnitude NMR signal amplification. This can be achieved either by direct hydrogenation of the thermally polarized precursor or by transiently binding parahydrogen and substrate to an organometallic catalyst. The latter scheme is known as signal amplification by reversible exchange (SABRE).

In this highly interdisciplinary Project at the interface of (quantum)physics, chemistry and biology you will put a cryostat for the production of parahydrogen into operation and use the PHIP or SABRE scheme for the hyperpolarization of interesting metabolites. Furthermore, you will learn how to use diamonds to detect nuclear magnetic resonances and record NV-NMR spectra of your hyperpolarized substrates. At last you will monitor the metabolism of single cells.

Tasks: Putting into operation a cryostat for the production parahydrogen, perform PHIP on a microfluidic chip

Techniques: NV-NMR, PHIP Hyperpolarization, Chemistry, Cell biology, Microtechnology

Skills: Ideally knowledge in NMR or hyperpolarization, chemistry and (bio)physics.

PhD position:

Dynamical pathways of N-heteropolycycles in the strong light-matter coupling regime.

Polaritonic chemistry seeks to modify reactivity and structure through coupling to the quantized photonic modes of resonance cavities. The field is in its infancy but growing quickly. In this PhD project, we will learn how to modify singlet fission and other energy transfer mechanisms in cavities from a first-principles quantum molecular dynamics perspective.

A fully funded PhD position is available in the Theoretical Chemistry Group, Heidelberg University, within the recently extended SFB 1249 (N-Heteropolyzyklen als Funktionsmaterialen) for the period 2021-2024.

Possible starting date: Sommer semester 2021 or earlier.

The strong light-matter coupling regime provides new opportunities to steer and control the structure and dynamics of molecular systems. Much progress in our group has been made towards simulating ultrafast dynamical processes in small molecules by quantum dynamics approaches. The main goal of this project is to discover general strategies to modify the process of singlet fission in N- heteropolycycles by exploiting the coupling to the photonic modes of a resonance cavity. The project involves the usage and further development of state-of-the-art quantum dynamics methods, as well as close interaction with the experimental groups in the consortium.

Masterarbeit experimentelle Radiologie

Untersuchung des Therapieansprechens maligner Pankreastumore mit Hilfe der Gesamtkörper-Magnet-Resonanz spektroskopischer Bildgebung (MRSI)

Wir suchen zwei motivierte selbständige Studenten/-innen mit hohem Interesse an experimentellen metabolen Bildgebung und der Bereitschaft 9 Monate vollen Einsatz zu zeigen. Wir bitten interessante Masterarbeiten in einem der aktuellsten Feld der Pankreaskrebsforschung, sorgfältige Betreuung, klar aufgestelltes Projektplan und viele Möglichkeiten zur Selbstentwicklung.

Rationale: Das Pankreaskarzinom zeigt überaus schlechtes Ansprechen auf die vorhandenen Therapien aufgrund einer hohen metabolen/strukturellen Heterogenität dieser Erkrankung. Unter diesen Umständen ist eine frühzeitige Prädiktion des Tumoransprechens, oder das Fehlen dieser, ausgesprochen wichtig für die gezielte Behandlung der Patienten. Dabei stellen bildgebende Untersuchungen des Tumormetabolismus, z.B. mit Hilfe der MRSI mit hyperpolarisiertem [13C]Pyruvat, eines der aktuellsten Forschungsgebiete für Pankreaskrebs dar.

Unsere Arbeitsgruppe verfügt über eine große Anzahl sehr gut charakterisierter und klinisch relevanter Mausmodelle, die für die oben beschriebenen Untersuchungen besonders geeignet sind. Zudem sind die fortschrittlichsten 3D-Ganzkörper MRSI Methoden etabliert und im Verlauf bereits getestet. Das Ziel dieser Arbeiten wäre die schnell eintretende Veränderung im Tumormetabolismus unter den klinisch relevanten Therapien (FOLFIRINOX und Gemcitabine/Abraxane) zu untersuchen.

Bei Interesse senden Sie bitte ein Anschreiben mit Lebenslauf und Zeugnissen an:
