Trapped Ion Imaging for Biomolecular Dynamics. The functionality of large biological molecules is driven by their chemical composition and the folded shape of their active form. The higher-order structure and dynamics of nucleic acids, proteins, carbohydrates, and lipids drives the chemistry of life. Combining single molecule microscopy and trapped ion mass spectroscopy will develop a new tool for precision measurements of higher-order folding dynamics in large biomolecules.

The functionality of large biological molecules is driven by their chemical composition and the folded shape of their active form. The higher-order structure and dynamics of nucleic acids, proteins, carbohydrates, and lipids drives the chemistry of life. Combining single molecule microscopy and trapped ion mass spectroscopy will develop a new tool for precision measurements of higher-order folding dynamics in large biomolecules. Optical techniques including Förster resonance energy transfer and super-resolution imaging can register changes in shape down to the nanometer scale. The uniquely adaptable ion trap environment enables manipulation of the surrounding solvent cage, temperature, and net charge down to the single quantum level. Read moreRead less
A study of ultracold atom interferometry and interactions through high-performance computing. This project involves a design and study of hyper-sensitive machines to detect changes in motion based on using clouds of atoms near absolute zero temperature. Matter at these ultracold temperatures can be harnessed to detect variations of both space and time, enabling novel quantum measurement devices to be built.
Molecular movies using time-resolved momentum spectroscopies. This project aims to use time-resolved momentum spectroscopies to take snapshots of chemical and physical processes as they evolve in time. This project expects to use these molecular movies to track the changes to electron motion after they have absorbed light. Expected outcomes of this project include understanding how the motion of electrons can drive physical processes and induce chemical changes. This will provide significant ben ....Molecular movies using time-resolved momentum spectroscopies. This project aims to use time-resolved momentum spectroscopies to take snapshots of chemical and physical processes as they evolve in time. This project expects to use these molecular movies to track the changes to electron motion after they have absorbed light. Expected outcomes of this project include understanding how the motion of electrons can drive physical processes and induce chemical changes.
