PhD Position - Optimization of 3D Devices for In Vitro and In Vivo Applications

Updated: 15 days ago

Your Job:

Neuronal model systems such as 2D and 3D cell cultures, brain organoids, and brain slices can physiologically mimic the brain, but require advanced electrophysiological measurement technologies to achieve long-term stable 3D recordings with single cell and millisecond space-time resolution to achieve an understanding of the function of such systems. While planar electrodes have been widely used, there are few approaches that focus on 3D geometries. Moreover, 3D microstructures help to support the organization of neuronal tissue at the single cell level, opening new avenues to physiologically relevant in vitro models. At our institute, we are developing methods to study three-dimensional neuronal networks at the level of single cells, whole networks and tissues. To this end, highly complex 3D structures are used to further improve the signal derivation of 3D nervous systems and to address important topics in life science research such as 3D network analysis, tissue engineering and organoid engineering.
Within IBI-3, we offer a PhD project aimed at improving already developed three-dimensional devices for in vitro and in vivo applications. New biomaterial combinations and geometries need to be tested to optimize the devices for their specific requirements such as electrical coupling, biocompatibility, flexibility and biodegradability.

Your tasks will include:

  • Get familiar with the high precision 3D printer located in the 1000 m² ISO 1-3 Clean Room facility of FZJ
  • Optimization of biomaterials selection and 3D printed geometries
  • Design, fabrication, application and characterization of new optimized 3D devices for in vitro and in vivo applications

Your Profile:

  • Master’s degree (or equivalent) in materials science, physics, chemistry, electrical engineering, or a related field
  • Ability to communicate with scientists and technicians from various disciplines
  • Well-structured and systematic research approach
  • Passion for science
  • Independent and analytical way of working
  • Advantageous, yet not mandatory, are experiences of using CAD software like CATIA / INVENTOR as well as programming knowledge in PYTHON / MATLAB
  • Interests in the field of Bioelectronics and Neuroscience

Please feel free to apply for the position even if you do not have all the required skills and knowledge. We may be able to teach you missing skills during your induction.
