Adaptive Synaptic Function and Neural Computation - Walter Lab
We investigate how synapses compute, adapt and remain functional across changing physiological conditions and neurological disease. By integrating quantitative neurophysiology, imaging, molecular biology and computational modelling, we uncover conserved mechanism of synaptic resilience.

The Walter Lab studies the molecular principles that enable the nervous system to process information while remaining adaptable and resilient throughout development, learning, aging, and disease. We investigate presynaptic release sites as conserved hubs where molecular organization, neuronal activity, and cellular signaling converge to regulate neurotransmitter release and plasticity. We combine electrophysiology, imaging, molecular biology, computational modeling, and cross-species approaches to connect molecular mechanisms with neural computation. Integrating the genetic power of Drosophila with human induced pluripotent stem cell (iPSC)-derived neurons allows us to uncover conserved mechanisms of synaptic resilience and explore therapeutic strategies for neurological disease.
Synapses continuously adapt to changes in activity, metabolism and disease while maintaining reliable information processing. We investigate the molecular mechanisms that enable this remarkable balance between flexibility and stability. Our work identifies presynaptic release sites as dynamic signaling hubs whose nanoscale organization regulates neurotransmitter release, short- and long-term plasticity, homeostatic adaptation and disease resilience. By combining genetics, quantitative physiology, super-resolution imaging, molecular biology and mechanistic modeling, we identify conserved principles of adaptive synaptic function across genetically tractable model systems and human neurons.
Our research combines quantitative electrophysiology, genetics, advanced fluorescence and super-resolution microscopy, molecular biology, biochemistry, behavioral analysis and computational modeling. Mechanistic modeling and quantitative inference allow us to integrate measurements across scales, distinguish competing biological mechanisms and generate experimentally testable predictions.
We combine the genetic power of the model organism Drosophila with patient-derived induced pluripotent stem cell (iPSC)-derived neurons to test whether conserved mechanisms of synaptic adaptation are preserved in human disease. Current work focuses on motor neuron disease and related neurodegenerative disorders.
