Associate Professor

He is the Head of the Environmental Engineering Laboratory, and his research interests focus on:

The reactions of zero-valent metals (e.g., Fe, Mg, Al, either individually or in combinations) under anaerobic conditions and in the presence of high bicarbonate concentrations, for hydrogen production. CO₂ sequestration occurs on the metal surface, and research is conducted on the reuse of CO₂-bound metals and the controlled release of CO₂. Mild synthesis methods for these metals are also being studied.
The integration of zero-valent metals into anaerobic processes for CO₂ conversion to CH₄, biogas upgrading, and CO₂ conversion to organic acids.
Anaerobic bioprocesses for the conversion of substrates into higher value-added products.
The study of anaerobic digestion under extreme conditions and the development of technologies for more efficient waste treatment and biogas upgrading.
Thermodynamic analysis (Gibbs free energy) of anaerobic digestion processes.
The study and optimization of anaerobic reactors (e.g., Submerged Anaerobic Membrane Bioreactor – SAnMBR, Sequencing Batch Reactor – SBR) for liquid waste treatment, as well as technologies for further treatment of anaerobic effluents.
