The Institute of Neurobiology at University of Luebeck offers a 
PhD Position on estrogen-mediated coupling in the central clock 
starting on June 1, 2024 or later. The successful applicant will work in the group of Dr. Violetta Pilorz on a DFG-funded project. This unique opportunity will allow the successful candidate to investigate the complex interplay of female sex hormones, in particular estrogen and progesterone, on the neuronal network of the central clock in the mouse hypothalamus, known as the suprachiasmatic nucleus (SCN), and its dynamic response to external stimuli.

This 3-year position, with possibility for extension, offers an excellent opportunity to contribute to cutting-edge research in neurobiology and chronobiology, thereby deepening our understanding of the complex mechanisms governing circadian rhythms and hormone regulation in the mammalian brain. 

Our recent findings Pilorz et al. (2020) and Schlaeger et al. (2024) shed light on the potential of estrogen to strengthen SCN coupling via astrocytic gap junctions, potentially enhancing its resilience to environmental fluctuations. The counteracting role of progesterone on estrogen functionality prompts us to investigate the differential effects of estrogen and progesterone on SCN coupling. Our primary goal is to elucidate the signalling pathways of estrogen and progesterone that might influence changes in intercellular coupling mediated by neurons and astrocytes. To achieve this, we will take a multifaceted approach, using organotypic brain slices from the PER2::LUC mouse model and working with hypothalamic astrocyte and neuronal cells. We also aim to validate our findings obtained in vitro using in vivo experiments by comparing the effects of estrogen and progesterone on SCN neuronal coupling in ovariectomised females under varying light and dark stimuli.

Requirements

•	hold a very good Master’s degree in neuroscience, molecular biology, chronobiology, molecular life sciences or similar subject
•	High motivation, solid organizational and strong teamwork skills, fluency in English and the willingness to work after office hours and at weekends
•	Experience in laboratory rodent experiments and knowledge of surgical procedures 
•	Possession of a Felasa certificate is an advantage but not a requirement

Application and relevant materials
•	Cover letter of max. 2 pages that specifies your research interests and its relation to the project
