Research interest

Dr. Leónidas Perez-Estrada scientific career is focused on the research and application of various advanced oxidation processes (AOPs) for the treatment and reuse of industrial/municipal wastewater, the use of High Resolution Mass Spectrometry to characterize emerging contaminants and its degradation products, and the use of Metabolomics techniques to identified chemical/biological markers produced in different oxidation processes. He has participated in 4 EU projects (FP6, FP7) and 4 major R&D water reclamation projects with various Canadian Oil Sands Companies. He has published more than 40 papers in SCI journals and has more than 50 international communications.

Track record

In 2016 Dr. Perez-Estrada joined the Solar Water Treatment unit at PSA. Previously he was Assistant Professor in the Department of Civil & Environmental Engineering at the University of Alberta (Canada). He is author of 1 National Editorial book, author/co-author of more than 40 publications in international high impact journals and more than 50 communications to different International Congresses and Symposiums. He has supervised/co-supervised 7 master (M.Sc., and M.Eng.) and 3 PhD students. He has taught various undergrad and graduate courses at the University of Alberta (Canada) and Graduate Seminars at the University of Almeria (Spain). H-index: 24 (Nov. 2017).
