Structural biology of cell surface receptors

I am a structural biologist dedicated to unraveling the molecular mechanisms governing cell surface receptor signaling, with a particular emphasis on their implications for human health and disease. By employing X-ray crystallography and cryo-electron microscopy coupled with structure-guided biophysical and cellular assays, I have elucidated numerous receptor-ligand interactions and downstream signaling pathways throughout my career. My research focuses on signaling pathways orchestrating the development of all multicellular organisms (Wnt, Bone morphogenetic protein, and Hedgehog), neuron growth (Neogenin-Repulsive Guidance Molecules and Plexins-Semaphorins), and synaptic transmission (gamma-aminobutyric acid receptors). My aim is to shed light on disease mechanisms and identify innovative strategies for therapeutic intervention, ultimately striving to improve patient healthcare.

If you require a structural perspective for your project, please feel free to email me. I am happy to assist with anything from advising on protein constructs and expression to analyzing the structure-function relationship of the target protein (e.g., the impact of mutations), and creating structural figures and movies for your papers.
