Research interests

Major objective of my research is to identify and characterize the molecular mechanisms underlying the ecological success of photosyntetic organisms and their capacity for handling different adaptative solutions in order to succeed in a variable environment. In this context, examples of environmental adaptations are the ones that take place in the marine diatoms, which display a suite of sophisticated responses (physiological, biochemical, and behavioral) to optimize their photosynthesis and growth under changing conditions. Marine diatoms are prominent microalgae in the contemporary oceans, several evidences indicated that diatoms dispose of a suite of sophisticated responses to optimize their photosynthesis and growth under changing conditions. However, the molecular mechanisms controlling diatom responses are still largely unknown. I’m trying to integrate genomic and genetic resources, with well-established physiological and biophysical approaches, to characterize light and nutrient regulated processes in diatoms.

I’m mainly focusing on the pathways of uptake and assimilation of N sources in diatoms and in plants as well, and, on the role played by ammonium and nitrate transporters as sensors of the external N conditions. In addition, I’m involved in a project aiming at deciphering the biogenesis and function of the diatoms silica cell wall (known as the frustule) and exploring his potential physical, optical and biotechnological applications. This is of fundamental importance in the understanding of the interactions of the living cell with the external environment.
