Short Biography
PhD in Civil and Environmental Engineering from the University of Girona.
Leads the research line in sewer systems at the Catalan Institute for Water Research.

Adjunct Research Fellow of the Advanced Water Management Centre (AWMC), the University of Queensland (Australia). 2005 joined the AWMC as Research Fellow in the frame of the Australian Research Council project “Understanding the Biotransformation Processes in a Sewer System to Achieve Optimal Management (LP0454182)”. January 2008 became Subproject 6 Leader for the SCORe (Sewer Corrosion & Odour Research) ARC LP0454182

Principal Investigator of the Marie Curie project SGHGEMS “Sulfide and Greenhouse Gas emissions from Mediterranean sewers” (PIRG08-GA-2010-277050) funded by the EU.
