Research Interests

My research interests are focused on the application of chemical engineering principles to the development of improved, more sustainable and environmentally-friendly processes, with particular focus on biological processes with open mixed cultures.

My current areas of research are the following:

- innovative processes for chemicals (ethanol, organic acids, hydrogen, methane) and energy production from lignocellulosic biomass and organic waste;

- biological wastewater treatment: process optimisation aimed at minimisation of reactor volume and energy consumption and maximisation of energy recovery through combination of aerobic and anaerobic processes; biodegradation of xenobiotics;

I have published 54 papers on international peer-reviewed journals which have received over 2,100 citations and my h-index is 23. I have published 1 book, 2 book chapters and 2 patents. I have over 60 papers or abstracts published as conference proceedings. I have reviewed papers for over 50 international scientific journals, for various conferences and research proposals for several organisations. I am in the Editorial Board of the journal "Process Safety and Environmental Protection". I have written over 100 internal industrial documents on various chemical engineering topics.

I am currently supervising 3 PhD students. The full list of my papers and citations is available here.
