Research Interests

We develop High-Speed Atomic Force Microscopy (HS-AFM) and other biophysical tools to understand how the structural dynamics of biomolecules (lipids, peptides, proteins, nucleic acids) correlate to their physiological functions. Our current interests include understanding the structure-function correlation of membrane proteins in native-like environments, the properties of biological membranes, membrane-protein interactions, protein self-assembly and aggregation, and protein-nucleic acid interactions. To accomplish these goals, we directly visualize the structural and functional dynamics of biomolecules in real-time (10 frames per second), in real space (~1 angstrom in vertical, ~1 nm in the lateral resolution), in the physiological fluids, and under various environmental cues using HS-AFM.

Prospective students and postdocs are encouraged to reach out via e-mail.

The Lin group is an interdisciplinary team of biophysicists and biochemists. We develop high-speed atomic force microscopy (HS-AFM) with various toolkits and correlated microscopes to visualize biological processes at single-molecule level. We are especially interested in scientists that are at the interface of biophysics, biochemistry, and molecular biology.
