The focus of my research is on the main factors that regulate nutrient (C, N, P, S, Fe) cycling in aquatic systems. Such factors include microorganisms, algae, seagrasses, and macroinvertebrates. I am particularly fascinated by the activity of electro-active bacteria. My work on this topic covers aspects such as their metabolism, geochemical impact, diversity, and potential applications in sensing and remediation technologies. I address these topics by applying a range of sensing and isotopic techniques
