Quantum effects in photosynthesis: responsible for highly efficient energy transfer or trivial coincidence? Understanding the precise details of the highly efficient energy transfer processes in photosynthesis has the potential to impact the design of efficient solar energy solutions. This project will gain this understanding by exploring the nature of interactions between different components and the significance of quantum mechanics.
A New Window on Photosynthesis: Ultrafast Coherence Dynamics in Biomolecules and Semiconductor Nanostructures. Recent research has indicated that the remarkable efficiency of energy capture and transfer in photosynthesis may be due to the effects of quantum coherence, which is an intrinsically non-classical phenomenon.

The impact of structural dynamics on three-dimensional bioimaging with X-ray free-electron lasers. X-ray lasers can potentially determine the structures of biological molecules that are inaccessible to existing techniques.

X-ray lasers can potentially determine the structures of biological molecules that are inaccessible to existing techniques. Intense ultrafast pulses encode the structure via diffraction faster than damage processes rip the molecule apart. In fact, damage processes begin during diffraction and remain problematic. It is not known if damage will prevent the determination of molecular orientations, a critical step in the experimental design. This project will solve this problem with a statistical theory, probing the feasibility and accuracy of the technique. The newly developed theory will enable us to perform experiments capable of measuring the effects of damage in biological molecules, paving the way for new methods of structure determination.Read moreRead less

Fundamental optics research underpins the commercial optical technologies of tomorrow. Modern examples of such evolution, from the fundamental to the commercial, include lasers, LED traffic lights, thin-screen computer monitors and digital cameras. The recent advent of accessible powerful computers, together with recent advances in optical physics, promise a powerful merging of computing and optical technologies into so-called virtual optical systems in which the computer processes optical information in a manner very similar to lenses. In particular, the computer may be used to decode distorted images provided by an imperfect imaging system. Read moreRead less

X-ray lasers produce powerful ultra-short pulses of light that can take temporal snap shots of small radiation-sensitive biological complexes. Thanks to superconducting technology, the next generation of x-ray lasers will be able to produce x-ray pulses at greater rates than ever before. But because of the sheer number of possible molecular configurations, these molecular movies will have only a small amount of data per frame, posing an enormous challenge for current imaging methods. I aim to meet this challenge by developing an innovative multi-conformational image reconstruction algorithm. This will provide a new window into the molecular dynamics of biological systems, the building blocks of life, and enable rational drug design.Read moreRead less

This project will develop a robust technique for the quantitative real-time imaging of high-temperature superconductors. The image-analysis algorithm so obtained will be a virtual software lens, which is able to decode the information contained in data obtained by a well-established but hitherto qualitative imaging technique. We will transform this technique into one uniquely capable of obtaining two-dimensional movies of the current distributions, magnetic fields, and pinning defects in superconducting films. Such a quantitative characterization of these key superconductor parameters will be an important tool in the present global quest for room-temperature superconductivity.Read moreRead less
