Dr. Stylianos I. Markolefas is a Mechanical Engineer. He graduated from the Department of Mechanical Engineering at the University of Patras in 1989. He pursued postgraduate studies (M.Sc.) at Rensselaer Polytechnic Institute (RPI) in the United States on a Research Assistantship, focusing on the development of innovative Finite Element methods (1992). Subsequently, he worked at RPI as a Research Engineer (1992–1993).

 In 1999, he commenced his doctoral research at the School of Applied Mathematical and Physical Sciences (SEMFE) at the National Technical University of Athens (NTUA). His dissertation, completed in 2004, explored the mathematical analysis of the p-version hierarchical finite element method with high-order polynomial interpolation and its applications in problems involving high numerical "pollution" in approximate solutions (wave equation, advection-diffusion problems).

 From 1999 to 2011, he was a permanent Scientific Collaborator (or Lecturer under Presidential Decree 407/80) in the Interdepartmental Postgraduate Program "Computational Mechanics" at NTUA, teaching courses on error analysis, adaptive techniques, and applications of general classical and mixed finite element methods. From 2004 to 2012, he taught a wide range of courses on Structural Mechanics and Computational Mechanics as a Scientific Collaborator at SEMFE (NTUA), the Athens Technological Educational Institute (TEI), ASPAITE, and the Chalkida TEI.

In Greece, he worked as a Structural Engineer, either as an associate engineer in major design firms or as an independent professional (Freelancer). From 2012 to 2014, he worked in Germany as an Aircraft Structural Engineer (Stress Engineer) at Sogeclair Aerospace and Eurocopter (Airbus Helicopters).

In July 2014, he was appointed Assistant Professor in the Department of Mechanical Engineering of the former Technological Educational Institute of Central Greece. There, he taught undergraduate courses in the structural domain, such as Strength of Materials, Statics, Dynamics-Vibrations, Fracture Mechanics, and Structural Analysis.

In March 2023, he joined the Department of Aerospace Science and Technology (AST) at the National and Kapodistrian University of Athens (NKUA). In the AST Department, he teaches undergraduate courses including Applied Mathematics, Differential Equations, and Computational Methods in Aerospace Science.

 Additionally, he has taught courses such as Basic and Advanced Vehicle Materials, Structural Vehicle Design, and Vehicle Dynamics Analysis, as part of the Master’s Program “Design and Manufacturing of Racing Vehicle Systems” at NKUA.

 His research focuses on the applications of Finite Element Methods in Nanomechanics and Microstructural Materials, Mathematical Analysis, and the applications of Classical and Mixed Finite Elements, as well as Gradient Elasticity theories. He also specializes in the stress and strain analysis of adhesively Bonded Joints with high-strength structural adhesives.

 Dr. Markolefas has published over 40 scientific articles in international journals and conferences. Furthermore, he has authored numerous standalone teaching notes for his courses. His published works have received over 600 citations, and he serves as a reviewer for scientific journals within his field of expertise.
