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 within 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. H-index (Scopus, Mar. 2016): 22.

Track record

In 2016 Dr. Perez-Estrada joined the Solar Water Treatment unit at PSA.
