Biologically engineering nanostructures to maximize energy, electron, and ion transport
… Artificial photosystems include light-harvesting antenna complexes and oxygen-evolving photocatalytic systems. In particular, a solid collaboration with Seth Lloyd's theory group inspires me to design a quantum light-harvesting antenna complex. The genetically engineered light-harvesting antenna …

DNA Origami Structures for Artificial Light-Harvesting and Optical Voltage Sensing
… origami plate as a mimic of a light-harvesting antenna complex required for photosynthesis. Such a structure allows us to systematically analyse optimal design concepts using different dye arrangements. Complementary to this, we use the resistive-pulse sensing technique in a range of …

Pigment orientation changes detected by low temperature linear dichroism spectroscopy: cold-hardening transition in phycobilisome-containing organisms
… to state 2, consisting of a tilt in the antenna complex with respect to the membrane plane. Linear dichroism spectra of PBS/thylakoid fragments from the red alga, Porphyridium cruentum, grown in green light (containing relatively more PSI) and red light (containing relatively more PSll) …

The physical origins of specimen movement in electron cryomicroscopy and how to eliminate it
… structures of biological macromolecules and complexes. Success in determining a structure by cryoEM depends on being able to prepare a thin frozen specimen of the molecules of interest on a small metal support, called a grid. Most high-resolution information loss in cryomicrographs stems from …

Light-Harvesting, Redox Control, and Biomimicry of the Photosynthetic Antennas of Green Sulfur Bacteria
… pigment. We have studied the two photosynthetic antenna complexes from these organisms that are responsible for light capture: the chlorosome and the Fenna-Matthews-Olson (FMO) protein.In regards to the chlorosome, we studied, using steady-state and time-resolved spectroscopic methods, the effect …
