Personal profile
Research Interests
My research focuses microbial physiology and water treatment. Regarding microbial physiology I study mechanisms of metal toxicity in bacteria and their translation into biotechnological applications. Currently, my lab investigates microbial metal metabolism and the development of sustainable materials for water treatment, including nanoparticle-based biofilters for antibiotic removal. My research combines interdisciplinary science with applied outcomes, aiming to understand microbial adaptation to increasing environmental metal loads and develop innovative solutions for environmental challenges.
