All my research is concerned with chloroplasts, the photosynthetic organelles of eukaryotic cells. It brings together the structure of photosynthetic membrane proteins with the evolution of the gene families that encode them, as well as the evolutionary origins of the chloroplasts themselves. We are currently investigating the amazing minicircular genes found in dinoflagellate chloroplasts‹each gene on its own individual minicircle of DNA, "one gene-one circle"! These were the first chloroplast gene sequences ever reported for dinoflagellates, a large group of unicellular marine algae
