**Meet the editor**

Dr. Alberto Adriano Cavalheiro was born in Araraquara, Brazil, in 1969. He graduated and carried out his PhD at the Chemistry Institute of Paulista State University. He is titular professor at Mato Grosso do Sul State University and has a researcher position at the Development Centre in Chemical Technology and in the Postgraduate Program in Natural Resources. Professor Cavalheiro and

his research group have concentrated efforts on two fields: phase transition mechanisms through X-ray diffraction and Rietveld refinement and morphological characterization of high-performance adsorbent materials, such as anionic clays. Recently, he began the study of graphene composites with anionic clays to increase the filtration power of contaminated water, aiming at direct human consumption.
