My research interests focus on agro-industrial waste treatment, bioreactor design, optimization of anaerobic bioprocesses and development of sustainable solutions for organic and liquid waste management. My research activities include both practical and technological aspects within biological process engineering and methodological issues in environmental biotechnology. Main activities concern projects related to biogas production and upgrading, production of high value-added products from biological processes and environmental microbiology. The innovative results of my research have been published in various peer-reviewed journals and international conference proceedings (>200 scientific publications, including >80 ISI publications, H-index 37). Finally, I have extensive experience in project implementation, as a scientific manager, coordinator or leader of work modules (GGEC, ERANET, LIFE, Horizon).
