Meet the editors

Dr Maaz Khan works as a Senior Researcher in PINSTECH, Pakistan. He has received his PhD and Post-Doctorate degree in material science. His research interests include fabrication of nanomaterials and their structural, optical, magnetic, and electrical characterizations. He has authored more than 100 research articles and published 8 books. Presently, he is serving as the Editor-in-Chief of "*Journal of Materials, Processing and Design*"

and Executive Editor of "*International Journal of Nano Studies & Technology*". He is also on the editorial board of several more journals in the material science field.

Dr Gustavo Morari do Nascimento is a professor at the Federal University of ABC. He has vast experience in many fields related to the characterization of nanomaterials using spectroscopic techniques associated to microscopic resolution. He obtained his doctoral degree from the University of São Paulo (USP) in 2004 with a thesis about the spectroscopic characterization of nanocomposites formed by conducting polymers and clays. Af-

terwards, he completed a post-doctoral degree at Massachusetts Institute of Technology (MIT) in the resonance Raman study of double-walled carbon nanotubes doped with halogens under the guidance of the legendary Mildred S. Dresselhaus. Back in Brazil, he spent three years (2009-2011) at the Federal University of Minas Gerais (UFMG) working on the synthesis of nanostructured carbon modified with molecular magnets. Nowadays, his research focus is on molecular characterization of modified carbon nanostructured materials and polymer nanocomposites using different spectroscopic techniques. Resonance Raman and SERS (surface enhanced Raman spectroscopy) coupled to microscopy techniques added to X-ray absorption techniques at National Synchrotron Light Laboratory have been the main techniques employed in the investigation.

Dr Marwa El-Azazy is an Analytical Chemist and "experienced educator and researcher" with 20 years of teaching experience at several institutions. Her main research interest is the construction of sensors (using microfluidic platforms for point-of-caretesting of drugs, bio-analytes, and ion-selective electrodes), chemometrics and analytical method development, spectroscopic analyses of drugs and pharmaceuticals, synthesis and

characterization of nanomaterials, and development of green chemistry approaches for wastewater treatment. Dr Marwa has a track record of research inputs including >30 refereed papers in prestigious international journals, several conference presentations, two book chapters, in addition to several research grants. She serves as a reviewer for a variety of international journals.
