Post-doctoral position in cell biology/cancer photobiology

Photothermal therapy (PTT) is one of the most efficient therapies that can induce necrosis of specific malignant lesions with minimal invasiveness and side effects compared with other therapeutic modalities.

In this context, applications are open for a postdoctoral fellowship position funded by the “FireLight” projet-FEDER – Photoactive molecules and nanoparticles.

The position will be based at L2CM (http://www.l2cm.univ-lorraine.fr/l2cm/), CRAN (http://www.cran.univ-lorraine.fr/) and ICL (http://www.icl-lorraine.fr/) laboratories in Nancy (France).

The research program will focus on the development of indocyanine green (ICG) loaded Solid Lipid Nanoparticles (SLN) and on the characterization of photophysical (size and charges measurements, spectral characterization, thermal effect) and photobiological properties (uptake, intracellular fluorescence and localization, therapeutic efficiency). The biological model used will be 2D and 3D cell cultures and animal models.

Selection process: Interested candidates should send a CV, a scientific track record, a motivation letter and two recommendation letters to:

Dr. Henri-Pierre Lassalle / Prof. Andreea Pasc

Contact: henri-pierre.lassalle@univ-lorraine.fr; andreea.pasc@univ-lorraine.fr

Skills/Qualifications: Candidates for this postdoctoral fellowship must hold a PhD degree in cell biology, good knowledge in photobiology will be required, as well as experience in animal experiments (the authorization to experiment on animals will be highly appreciated). Creativity, autonomy and strong reliability are highly required. All applicants must be able to communicate fluently in French and/or English (speaking and writing). The position is available for a period of 18 months, starting from September 2020.

Post-doctoral position in organic chemistry/photo-bio-chemistry

Over the last decade, photothermal therapy (PTT) have attracted increasing attention as a potential alternative to classical ones. It involves both molecules or nanoparticles absorbing photons upon NIR irradiation and generating heat through non-radiative relaxation pathways.

In this context, applications are open for a postdoctoral fellowship position funded by the “FireLight” projet-FEDER – Photoactive molecules and nanoparticles. The position will be based at L2CM laboratory in Nancy (France). The research program will focus on the synthesis of calixarene derivatives and the characterization of the optical and photophysical properties of the resulting molecular self-assemblies and calixarene-MoS2 nanoparticles assembled systems. The project will also include photobiochemical characterization triggering anti-bacterial applications.

Skills/Qualifications: Candidates for this postdoctoral fellowship must hold a PhD degree in organic chemistry, preferably with experience in photobiochemistry. Creativity, autonomy and strong reliability are highly required. All applicants must be able to communicate fluently in French and/or English (speaking and writing). The position is available for a period of 18 months, starting from September 2020.

Selection process: Interested candidates should send a CV, a scientific track record, a motivation letter and two recommendation letters to:

Prof. Jean-Bernard Regnouf de Vains / Prof. Andreea Pasc

PhD position: Photoactive Iron Complexes: Design and Application to Solar Energy

Filled

The aim of the thesis program is to develop photosensitive compounds from low-cost and environmentally friendly metal complexes. While ruthenium complexes have been widely studied and used in many laboratory applications because of their ideal photophysical properties, ruthenium is a rare, toxic and expensive metal, which limits real industrial development. Our project aims to replace this metal with other metals such as iron, which is strategic in the search for low-cost devices and industrial processes that conserve resources. In particular, we are targeting the development of photosensitizers for the manufacture of dye solar cells (DSSCs).

PhD project: Study and development of polar organometallic tools: towards the preparation and selective functionalization of heterocycles

Filled

The synthesis of (hetero)aromatic compounds is an omnipresent challenge for the organic chemist due to their multiple and varied applications. Indeed aromatic and heterocycle moieties are everywhere in day life, either in materials science, optics, electronics or biology. Thus, researches in organic synthesis methodologies are continually in progress for the preparation of heterocycles and their functionalization.

That is why, the aim of this PhD project is to develop original organometallic reagents to allow the development of innovative synthetic sequences for the preparation of highly functionalized (hetero)aromatic derivatives. In particular, we will focus our attention on bimetallic ate complexes as metalating reagents for metal-halogen exchange (MHE) or deprotonation. Their design, preparation and reactivity will be studied at first on heterocycle model and then exemplify to various heterocycles. Bimetallic ate complexes result in combining a polar organometallic (e.g. an organolithium) with a “soft” organometallic (organomagnesium for example), which the behaviour is different from those of the precursor. The principle is a synergy created by mixing two different organometallic reagents allowing increased selectivity and reactivity as well as use under non-cryogenic conditions compared to the monometallic reagent.

Post-doctoral in coordination chemistry at the interface with biology

Filled

Project AIM +: Anticancer Iron Made+ AIM+ is a multidisplinary project at the interface between chemistry and biology. The aim is to develop a novel type of DNA hypomethylating agents able to bind DNA and to chemically induce its direct demethylation. Based on preliminary results showing a decrease in the 5‐methylcytosine level as well as a strong reduction of cell proliferation, our project aims to achieve the comprehension, at the molecular level, of its action mode. Our final goal is to develop an entire novel class of epigenetic drugs and harness their ability to control cell proliferation for therapeutic purposes. For this, AIM+ project will enhance, via proper chemical modifications, the demethylating activity and the selectivity of the proposed system. AIM+ is based on a multidisciplinary consortium gathering synthesis, molecular modelling and biology. The aim of the postdoctoral fellowship is to synthesise and characterize a range of new hypomethylating agents based on the preliminary results obtained by the consortium.
