Since A.Y. 2014-2015 Erasmus Institutional Coordinator.
1. Microbial Fuel Cells for Wastewater depuration and electric energy production.
In collaboration with the Department of  Electrical, Computer and Biomedical Engineering, has tested different materials for cathode and anode, different dimensions and layout of the cells.
Microbial Fuel Cells (MFCs) are systems capable to convert chemical energy, contained in an organic biodegradable substrate, into electrical energy, through the mediation of exo-electrogenic bacteria that act as catalyser of  the  half-reaction  of  substrate  oxidation. When wastewater is used as anode fuel, MFCs perform waste-water treatment while recovering energy, thus leading to the possibility of energy-producing wastewater treatment plants. Some prototypes were built at the laboratory Labta2 (University of Pavia, Italy). 
2. Membrane Biological Reactor
In collaboration with the Academic Spin-off of the University of Pavia UN.E.CO., has developed an innovative BCR (Biological Compact Reactor) , based on the use of ultra-light molecular weight polyethylene membranes. The study has been focused on removal of MtBe (Methyl Ter Butyl Ether) and other gasoline compounds from groundwater.
3.Phosphorus recovery 
Is currently part of the reserch team of a project financed by CARIPLO foundation for the recovery of nutrients (most importantly, P) from waste sludges. Phosphorus will be recovered as Struvite  (magnesium 
ammonium orthophosphate) wich, contrary to the waste sludge as is, is considered an ideal fertilizer, and as such is quite valuable. Tests of struvite precipitation are conducting in the laboratory Labta2 (University of Pavia, Italy), from sludge as is, with variable pH, and in controlled pH conditions. After definition of the process in the laboratory, the same will be implemented in a pilot plant.
