Understanding and Engineering the Brain at the Molecular Scale
The brain is an intricate system where molecular interactions drive neural computation, plasticity, and disease progression. We aim to uncover the molecular principles underlying neural function and develop innovative bioengineering tools to study and manipulate neural activity. Our work spans fundamental biophysical mechanisms, synthetic biology, and translational neuroengineering, with a long-term goal of bridging basic neuroscience with therapeutic applications.

We take an interdisciplinary approach, integrating structural biology, protein engineering, synthetic biology, and neurobiology to study neural function and design novel tools for neuroscience and medicine.

Neurons rely on precise molecular interactions at the cell surface to transmit signals, process information, and adapt to their environment. We study how proteins, receptors, and ion channels contribute to neural function at the molecular level.

  • Investigating biophysical and biochemical mechanisms of neural signal transduction.
  • Mapping protein-protein interactions that regulate cell surface signaling.
  • Developing new techniques from structural and mechanistic insights.

By leveraging synthetic biology and protein engineering, we develop molecular tools to control and manipulate neural activity with high precision.

  • Developing novel biointerfaces for studying neural function in vitro and in vivo.
  • Enhancing expression systems in the brain for better delivery.
  • Applying synthetic evolution and computational methods to optimize neural tools.
