Diego is a Plant Physiologist based at the University of Birmingham, UK. He specialises in studying photosynthesis and water-use efficiency through gas exchange and stable isotope techniques. His research integrates theoretical biophysics with experimental methods to develop mechanistic models of carbon fixation, CO₂ diffusion, and plant hydraulics. By combining carbon and water isotope measurements, he investigates how CO₂ and water move within leaves, shedding light on mesophyll CO₂ gradients, diffusion resistances, and their impact on plant function.
