Dr. Eng. in Engineering (2013), Master's in Mechanical Engineering (2000), Aeronautical Engineer (1993).

Since March 2019, he has been working as an academic affiliated with the Institute of Industrial Design and Methods at the University of Austral de Chile (UACh). His academic activities, as well as technical advisory and consulting work, are in the areas of instrumentation and measurement, as well as mechanical systems dynamics. He currently serves as the coordinator of the Innovation, Entrepreneurship, and Technology Transfer Office of the Faculty of Engineering Sciences at UACh.

From September 1995 to January 2018, he was a faculty member at Simón Bolívar University (USB, Venezuela), affiliated with the Department of Mechanical Engineering. At USB, he became a full professor in September 2014 and held various academic-administrative positions, including educational coordinator for postgraduate programs in mechanical and civil engineering (2017-2018), educational coordinator for mechanical engineering (2010-2016), and head of the machine dynamics section at Laboratory A (2002-2006). He also served as a faculty representative on the Board of Directors and the University Council at USB, and was a member of the credential evaluation committee for the Department of Mechanical Engineering and the advisory council for mechanical engineering coordination. His teaching efforts at USB were recognized three times with the Annual Outstanding Teaching Award, presented by the Academic Vice Rector's Office at USB, in the categories of Full Professor (2016-2017), Associate Professor (2013-2014), and previously, Assistant Professor (2003-2004). He supervised over ninety final degree projects, including undergraduate projects, business internships, and final projects for the Specialization in Mechanical Engineering.

Dr. Eng. Medina served as the academic supervisor for more than ten years for the ASME-USB student group, which is affiliated with USB and recognized by the American Society of Mechanical Engineers (ASME).

He was a Visiting Fellow at the School of Mechanical & Manufacturing Engineering, University of New South Wales (Sydney, Australia), during his sabbatical year in the period 2009-2010.

Dr. Eng. Medina's applied research areas include topics such as mechanical system identification, considering experimental uncertainties, passive and active control of mechanical vibrations, as well as metrology through uncertainty estimation in metrological processes and variance analysis applied to measurement problems in engineering. As a lead author and co-author, he has publications in peer-reviewed conference proceedings and journals. He has also served as a technical reviewer for articles and for the sixth edition, in the International System of Units, of the book "Mechanical Vibrations" by Singiresu S. Rao, a recognized fundamental reference in mechanical vibrations used as a basic textbook by various mechanical engineering schools.

Dr. Eng. Medina's technical advisory and consulting services encompass technical measurement and analysis of vibrations in rotating machinery, static and dynamic calibration of industrial transducers used for monitoring the vibration of rotating equipment in oil extraction. He has also facilitated professional development courses in mechanical vibration measurement and analysis, as well as courses on metrology applied to uncertainty estimation and quality control of industrial processes. Furthermore, he has participated as a methodological supervisor in projects for the implementation and continuous improvement of maintenance management and industrial services.
