Shape-Shifting Molecules: Photoisomerization Action Spectroscopy. This project aims to examine molecules that change shape in response to light in order to gain insight into the biological processes they control. Many biological systems, including the human visual apparatus and bacterial photosynthesis, depend on molecules that change shape in response to light. The project plans to probe shape-shifting molecules with laser light while they are propelled through gas by an electric field.

This project aims to examine molecules that change shape in response to light in order to gain insight into the biological processes they control. Many biological systems, including the human visual apparatus and bacterial photosynthesis, depend on molecules that change shape in response to light. The project plans to probe shape-shifting molecules with laser light while they are propelled through gas by an electric field. Light-induced changes in molecular shape produce detectable variations in drift speed. The ensuing knowledge would help calibrate computational approaches for predicting molecular function. It would also establish foundations for understanding essential biological molecules, including retinals, carotenes and peptides, and for developing new light-activated molecular motors and switches.Read moreRead less

Laser spectroscopy of functional molecules. Frontier techniques of molecular laser spectroscopy and mass spectrometry will be developed and deployed to investigate the structure and function of molecules that underpin biological processes, drugs, and single molecule devices, including molecular motors, molecular switches, and energy harvesting systems.
Getting the drift - new frontiers in ion spectroscopy. This project will develop and harness ultra-sensitive techniques to understand the action of photo-active molecules involved in human vision, molecular motors and molecular memory. The new techniques will also help explore and exploit the properties of carbon and silicon nanoparticles, and may assist detection of exotic molecules in space.
