Pulling biomolecular complexes
MBI scientists demonstrate how the phenomenon of force-induced stabilization of biomolecular complexes can be explained on a one-dimensional energy landscape by incorporating defined transition coordinates.

More twists to the tale: Varied actin patterns in epithelial cells
A recent study led by MBI graduate student Salma Jalal and Senior Research Fellow Tee Yee Han reveals differences in actin organization patterns observed in fibroblasts and epithelial cell subtypes.
Appreciation evening for MBI’s Founding Director
On Friday 28 June 2019, MBI held an appreciation dinner for Prof. Michael Sheetz to mark his time as Director of MBI. Prof. Sheetz has been MBI Director since its inception, having been recruited by Prof. Hew Choy Leong to lead a new RCE in Mechanobiology in 2008.

Research Interests
Molecular Mechanisms of Mechanobiology
My current research has been focused on the molecular mechanics of cell mechanotransduction studied at a single-molecule level, which forms the foundation to understand the cell migration, tissue formation and maintenance, and the mechanobiology-associated translational biomedical applications.
- Single-molecule mechanobiology and biophysics at cell-ECM adhesion and cell-cell junctions;
- Single-molecule mechanobiology and biophysics at nuclear-cytoskeletal linkages and cell cytoskeleton;
- Biophysical studies of gene regulations, DNA replication and repairs by various single-DNA manipulation assays.
