Sara Vallejo Castaño
Postdoctoral Researcher
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.
