Ahmed Mubarak is currently a Professor of Inorganic Chemistry and leader of the Catalysis Research Group at the Chemistry Department, Faculty of Science, King Khalid University, Saudi Arabia. He is a member of the Saudi Chemical Society, Head of the Chemistry Department 2004–2008, Vice Dean of the Science Faculty 2008–2010, Dean of Research at King Khalid University 2011, and Vice President of King Khalid University for Research and Graduate Studies 2011–2015. He obtained his PhD in Chemistry in 1999 from Nottingham University, UK. He has authored and coauthored more than 50 articles in peer-reviewed and highly reputed ISI journals. He has also edited a few books and supervised and reviewed graduate students in both MSc and PhD degrees. He has participated in international and local conferences in the UK, USA, KSA, France and other countries. He is the main researcher in three big projects with King Abdulaziz City for Science and Technology, KSA, and one project with SABIC, KSA, on metallocene catalysis used for polyethylene production. He works with collaborators/researchers with mutual interests from many institutes and universities. His research interests are primarily in the areas of catalysts and using different techniques related to environments and petrochemical treatment using catalysis at the nanoscale, the growth of varying forms of nanostructured materials and their basic characterization by XRD, SEM, TEM, spectrophotometric techniques towards the correlation nature of heterogenous catalysis and nanocatalysis, their properties, and applications.
