Sara Vallejo Castaño

Scientific project manager

Biography

My research focuses on the design, characterization, and upscaling of electrochemically driven systems for CO₂ capture and purification from flue gas steams using bipolar membrane electrodialysis. I have also developed lab and pilot scale processes for mineral recovery and renewable energy generation.
