Research Interest

The research interests of Helena Nadais are centered on biological processes for the treatment and material/energetic valorization of wastewaters and wastes. She has done substantial work on the development of a novel strategy for the operation of biological systems towards the valorization of wastes allowing the raising by around 25% of the bioenergy (methane) production from industrial wastewaters in parallel with the monitoring of the key microbiological groups thriving in such optimized systems. Presently she is focused on microbial fuel cells for energy production from domestic wastewaters.
