  • Materials Laboratory


Dr. Badurina is an applied mineralogist with strong experience in a wide range of material characterizations and analytical techniques comprising of quantitative XRF-WDS and XRD analyses, SEMEDX, LA-ICP-MS and FTIR, with results published across 13 peer-reviewed publications. Dr. Badurina is an expert in complex interpretations of many diverse matrices, ranging from volcanic ashes, bentonites, sands, clays, silica polymorph mixtures to cements and fly ashes. His analytical expertise encompasses diverse portfolios including projects with variety of bentonite occurrences across central and SE Europe, ophiolite deposits, method development of LA-ICP-MS in micro-analysis of clay minerals, and many more. Dr. Badurina’s expertise in highly specialized quantitative XRD made a significant impact on understanding commercial heat-treated silica products.

At CTLGroup, Dr. Badurina specializes in specialized materials characterizations and method developments, forensic investigations, emerging technologies and research projects as well as litigation. Dr. Badurina focuses on XRF and XRD analyses of cementitious materials, cements, clinkers, supplementary cementitious materials such as ashes, slags, and a wide range of inorganic raw materials and aggregates. Dr. Badurina brings his extensive background in clay and general mineralogy for interpretations of complex mineral mixtures.
