We invite applications from interested candidates for the following position, available immediately: PhD position in Cellular Neurobiology (m/f/d) (full time; 3 years) Our recently established research group develops and studies human-relevant models for neurobiology. We use induced pluripotent stem cells to generate cell-based models of the human brain, so-called brain organoids. These 3D brain models allow us to study neurotoxicity, factors influencing neurodevelopment - such as sex hormones, environmental toxicants, and genetic or developmental disorders - and the mechanisms shaping early brain function. About the PhD project: In this project, you will generate and characterize human brain organoids from male and female donors and analyze their electrophysiological activity using multi-electrode array (MEA) technology. A central goal is to quantify electrophysiological network metrics and connect them to developmental trajectories within the organoids. You will investigate how the factors mentioned above affect early network formation, cellular differentiation, maturation, and functional connectivity in this model system. Your profile: Motivated, reliable scientist with organizational and problem-solving skills Communicative, enthusiastic team player BSc and MSc in Biology, Neuroscience, Biochemistry, Bioinformatics, or related fields Hands-on experience in e.g. Cell Culture, Omics approaches or Molecular Biology Basic programming skills (e.g., Python or R) or motivation to learn Fluency in English is required; German skills are an advantage, primarily for interactions outside the lab What you can expect at Constructor University: We are an international, world-class private university embarking on an exciting journey of growth and expanding our portfolio.
