Daniele Di Trapani graduated in “Environmental Engineering” at Palermo University in 2004. He has been Ph.D. Student in the period 2006-2008, spending almost one year as visitor Ph.D. student at the Norwegian University of Science and Technology in Trondheim (Norway), under the supervision of Professor Hallvard Ødegaard. The topic of his research focused on the use of advanced processes for wastewater treatment and in particular on hybrid MBBR (moving bed biofilm reactor) systems. He received the Ph.D. degree from the University of Palermo, after the Final Dissertation of his original thesis “Reattori ibridi a biomassa sospesa e adesa per il trattamento delle acque reflue”. The supervisor of his PhD thesis was Professor Gaspare Viviani. He got a Post Doctoral position at the Department of Hydraulic and Environmental Engineering of Palermo University, which research topic was the analysis of the biokinetic behaviour of hybrid moving bed biofilm reactors. In the period 18 September 2013 - 17 September 2015 he got a Post Doctoral Fellow Position at the Department of Civil, Environmental, Aerospace, Materials Engineering (DICAM), in a research project which focuses on biological treatment of saline slops contaminated by hydrocarbons. From the 22nd of September 2015 to the 21st of September 2016 he was Post Doctoral Fellow at DICAM in a research project which aim was the investigation of greenhouse gas emissions from advanced wastewater treatment. From 22nd of December 2017 to the 21st of December 2020 he was Assistant Professor (RTDA) in Sanitary and Environmental Engineering at the DICAM and then at the Department of Engineering (DI) of Palermo University. From the 4th of January 2021 he is Assistant Professor (RTDB) in Sanitary and Environmental Engineering at the Department of Engineering (DI) of Palermo University. He also works in the fields of contaminated Soil Remediation and Municipal Solid Waste management, focusing in particular with uncontrolled methane emissions from the surface of sanitary landfills as well as with leachate production and distribution inside MSW landfills. From the Academic year 2018/2019 is is the teacher of "Contaminated Site remediation" in the Master Degree Course "Engineering and Innovative Technoligies for the Environment". Dr. Daniele Di Trapani has (co-)authored over 100 refereed publications in ISI journals, conference proceedings and book chapters.
