RNA biology and engineering, emerging from basic single-cell research to tool developments for nucleic-acid based therapies, all at the single molecule level
Reveal the spatial and temporal information of single molecules in individual cells

Cellular behavior depends on the activities of countless individual biomolecules. Compared to population-based methods, the ability to simultaneously perturb and analyze individual molecules provides a more direct and quantitative understanding, and unprecedented insights, of how these molecules function. We are passionate about performing these single molecule studies in individual cells, to quantitatively investigate important but currently inaccessible molecular and cellular biology questions, and then to achieve more predictive cellular manipulation.
Reveal the dynamics and kinetics of single molecules at subnanometer resolution
While single cell studies can reveal the behavior of different molecules in a cellular context, understanding how they perform specific biological function requires an exquisitely detailed view of molecular mechanism. Using a powerful single molecule tool - Magnetic Tweezers, we aim to systematically and quantitatively acquire the dynamics and kinetics of molecular interactions at a sub-nanometer micro-second resolution, and then to correlate their behaviors in the cellular context and achieve programmable molecular engineering in mammalian cells.
