Luca Sergi is a PhD researcher in physics based in Cagliari, working in computational neuroscience with a focus on synaptic plasticity and learning in biological systems.
His work shows that structural plasticity can significantly improve learning capability and generalization, offering insights relevant both to neuroscience and machine learning.
Beyond academia, he is deeply curious about artificial intelligence, neuro‑inspired computing, and how theoretical models can translate into real‑world technologies.
Sports, outdoor activities, and exploring new ideas in science and technology help him stay balanced, curious, and creative.
Modeling Learning in the Brain
Luca’s research centers on understanding how learning arises in biological neural networks. By developing mean‑field theories and implementing both spiking and rate‑based models, he studies how neural systems adapt through synaptic plasticity.
A central theme of his work is structural synaptic plasticity, the idea that changes in network connectivity itself, not only synaptic strength, play a crucial role in learning.
His results suggest that allowing networks to rewire improves both learning efficiency and the ability to generalize beyond training data.
Structure Matters
One of Luca’s key insights is that learning performance improves when neural models are allowed to modify their structure dynamically. This challenges simplified learning paradigms and brings computational models closer to how real brains operate.
“Learning is not only about adjusting weights, it is also about reshaping the network itself.”
This perspective opens new directions for both neuroscience research and the development of more flexible and robust artificial learning systems.
Curiosity Beyond Neuroscience
Outside his core research, Luca is strongly interested in artificial intelligence, digital innovation, and neuro‑inspired computing. He is particularly curious about how ideas from computational neuroscience can inform machine learning, data science, and brain‑inspired technologies.
He sees strong potential in translating theoretical models into applied contexts, bridging fundamental research with real‑world technological impact.
Building Meaningful Connections
Luca is eager to connect with researchers and professionals working at the intersection of neuroscience, AI, and computational modeling. He is also interested in engaging with people involved in applied research and technology transfer.
For him, collaboration is a way to expand perspective, test ideas across disciplines, and move closer to applications that matter beyond academia.
Energy, Balance, and the Road Ahead
Outside of work, Luca enjoys practicing sports, spending time outdoors, and exploring new ideas in science and technology. These activities help him maintain balance while staying intellectually energized.
Looking ahead, he aims to strengthen his skills in data science, machine learning, and interdisciplinary collaboration. A key goal is to improve his ability to translate theoretical insights into practical applications, turning models into tools that can inform both science and technology.
