About us
The University of Luxembourg is an international research university with a distinctly multilingual and interdisciplinary character.
The Luxembourg Centre for Systems Biomedicine (LCSB) is an interdisciplinary research centre of the University of Luxembourg.
We conduct fundamental and translational research in the field of Systems Biology and Biomedicine - in the lab, in the clinic and in silico. We focus on neurodegenerative processes and are especially interested in Alzheimer's and Parkinson's disease and their contributing factors. The LCSB recruits talented scientists from various disciplines: computer scientists, mathematicians, biologists, chemists, engineers, physicists and clinicians from more than 50 countries currently work at the LCSB. We excel because we are truly interdisciplinary, and together we contribute to science and society.
The Developmental and Cellular Biology Group (led by Prof. Jens Schwamborn) at the Luxembourg Centre for Systems Biomedicine has an opening for a PhD position in the emerging field of organoid intelligence (OI), the use of three-dimensional human brain organoids as a living, adaptive computing substrate. The successful candidate will establish a reservoir computing platform in which a human brain organoid serves as the physical reservoir. Time-dependent inputs are encoded as spatiotemporal patterns of electrical stimulation delivered through a high-density multielectrode array (MEA); the organoid's nonlinear network dynamics and fading-memory properties transform these inputs into high-dimensional states that a trained readout layer maps onto computational tasks.
Your role
The PhD project will combine organoid generation and long-term maintenance, MEA-based stimulation and recording, and closed-loop training protocols to probe how activity-dependent plasticity in the organoid reshapes functional connectivity during learning. The aim is both to advance OI as a computing paradigm and to use it as a window onto the cellular and network correlates of learning and memory in human neural tissue. The work is highly interdisciplinary, bridging wet-lab neurobiology, electrophysiology and computational analysis.
Your profile
- Master's degree (or equivalent) in neuroscience, bioengineering, biology, biophysics or a closely related field
- Hands-on experience with multielectrode array (MEA) technology - electrophysiological stimulation and recording, and analysis of extracellular network activity is required
- A solid background in neurobiology, ideally with knowledge of the mechanisms of learning and memor, e.g. synaptic plasticity, long-term potentiation, neural network dynamics
- Experience in human stem cell biology and work with organoids, e.g. iPSC culture, neural differentiation, brain organoid generation is a strong asset
- Familiarity with data analysis and scientific programming, e.g. Python or MATLAB, and an interest in concepts from reservoir computing or machine learning, is welcome
- A genuine interest in interdisciplinary research at the interface of biology, engineering and computation, and the ability to work both independently and within a team
