Self-introduction：

Dr. Wu received a B.S. degree in Biological Science from Nanjing University in 2016, and obtained his Ph.D. degree in Life Science with Dr. Mingjie Zhang at Hong Kong University of Science and Technology in 2021. He continued postdoctoral training until 2024, where he systematically demonstrated that the presynaptic terminal is profoundly organized via phase separation. He joined Southern University of Science and Technology in 2025 as an assistant professor, and devoted to understanding how phase separation contributes to presynaptic organization and function, as well as general implications of phase separation in communication between membraneless condensates and membranous organelles. Dr. Wu has published in Cell, Molecular Cell, Developmental Cell, Annual Review of Neuroscience, ect.

Research Interests：

Phase separation has been increasingly recognized as a general principle of cellular compartmentalization. Neuronal synapse is a highly specialized and polarized structure, where synaptic compartmentalization fundamentally participates in neuronal assembly and function. We are committed to investigating how phase separation underlies presynaptic compartments formation and dynamic regulation, as well as their functional implication to synaptic transmission, synapse formation, and synaptic plasticity. We particularly interested in:

◆ How does phase separation orchestrate synaptic vesicle cycling?

◆ How do multiple compartments interact with each other in the presynaptic bouton?

◆ How do pre- and post-synaptic compartments synergize with each other in response to synaptic stimulation and plasticity?

◆ How does phase separation contribute to membraneless condensates communication with membranous organelles in general?
