Prof. Dr. Ştefan Ţălu completed his degree in Mechanical Engineering at the University of Craiova, Faculty of Mechanics, Romania in 1988. He received his Ph.D. degree (in technical sciences with a specialty in the technology of machine building) and Associate Professor from the Technical University of Cluj-Napoca, Romania, in 1998 and 2002, respectively. Since completing his training as a specialist in technical sciences and fractal/multifractal applied techniques, he has worked in academia conducting research in the technical sciences (full Assoc. Professor PhD., full-time). He has an academic position at the Technical University of Cluj-Napoca in the Department of Research, Development, and Innovation Management (DMCDI), and Faculty of Mechanical Engineering, Department of AET, Discipline of Descriptive Geometry and Engineering Graphics (DGEG). His research interests include: Mechanical engineering; Mechanical and tribological characterizations of macro-micro-nano structures; Topographical and morphological characterizations of three-dimensional surfaces; Computer-aided engineering and Designing industrial processes; Experimental techniques for micro/nano mechanical and micro/nano tribological characterizations; The development of new mathematical tools in the investigation of 3-D surface quality; Research in design and testing of mechanical components for different operating conditions; Biostatistics, Molecules/Biomolecules; Nanotechnology in Science and Technique.
