Profile and career

A career across engineering, science, and academia

International education, professional practice, research, and knowledge transfer.

The career of Lenin Marcelo Moncayo Theurer represents one of the most notable trajectories in civil engineering, scientific research, and academic rigor in contemporary Ecuador. A Full Professor at the University of Guayaquil—a position obtained through a rigorous merit-based competition—scientific researcher, author, and director of the THEK Research Institute, his career spans more than 25 years devoted to the production, teaching, communication, and application of technical knowledge in service to society.

His strong international education forms the foundation of a global scientific vision deeply committed to excellence. Moncayo Theurer completed his undergraduate studies in civil engineering at Escuela Superior Politécnica del Litoral (ESPOL), under the guidance and thesis supervision of the recognized academic and researcher Eng. Otton Lara Montiel. He later pursued specialized postgraduate studies in earthquake engineering in Japan, supported by a Japan International Cooperation Agency (JICA) scholarship, receiving specialized training at the Building Research Institute (BRI) / International Institute of Seismology and Earthquake Engineering (IISEE) and at the University of Tokyo under Professor Kenichi Ohi, focusing on structural reduction and the energy-absorption capacity of frames.

He then deepened his theoretical and computational specialization by earning the degree of Master of Science (M.Sc.) in Computational Mechanics at the prestigious Technical University of Munich (TUM) in Germany—supported by a scholarship from the German Academic Exchange Service (DAAD)—where he worked directly alongside leading international figures in computational mechanics and structural analysis, including Professor Kai-Uwe Bletzinger, Manfred Bischoff, Ernst Rank and Alexander Düster.

Over more than two and a half decades of professional practice, his work has been reflected in major infrastructure projects nationwide. He has led and participated in emblematic civil-engineering projects in Ecuador, including construction management and supervision of critical infrastructure, structural design of high-rise buildings, multilayer bridges, and industrial facilities. This extensive practical experience in construction oversight and earthquake-resistant design has provided an empirical foundation for his continuing research in structural dynamics, the finite element method (FEM), advanced numerical methods, and mathematical modeling of complex Earth systems.

As an author and academic, his intellectual output is prolific. He has written and published 15 books focused on Earth sciences, structural engineering, and geophysics—including internationally distributed works such as Tectónica de Placas, available and distributed through global platforms such as Amazon KDP—and has consolidated an open-science portfolio comprising 24 principal records on Zenodo, together with contributions on international platforms such as Figshare and ResearchGate, where his work has recorded thousands of reads and interactions across dozens of countries and research centers worldwide. His Google Scholar profile reflects the sustained impact of his publications, with more than one hundred citations and an established h index.

In the methodological field, Moncayo Theurer has developed original engineering frameworks and frontier scientific methodologies, including SERRA/MEL (Seismic Energy Release and Redistribution Analysis / Modelling Equivalent Magnitude), conceived to transform complex seismic catalogs into dynamic energy-release curves without relying on arbitrary statistical thresholds. His work is complemented by the creation of the THEK, which institutionalizes a permanent channel for altruistic knowledge transfer to new generations of engineers.

Beyond academia, Marcelo Moncayo has maintained a significant public role in Ecuador, frequently consulted by mass media—including the newspaper El Universo—following major seismic events, translating the complexity of Earth sciences into accessible explanations for the public with pedagogical rigor.

Principles and Philosophical Thought on Education (Classical Confluence)

Knowledge, education, civic responsibility, and service.

In his view of higher education, knowledge, and the education of future professionals, Marcelo Moncayo Theurer’s thought draws on the guiding principles of classical Western philosophy—with particular resonance in the Aristotelian and Platonic distinctions addressed in his essays and public reflections—:

1. The Distinction Between Experience and Science (The Aristotelian Legacy): In keeping with the principles of Aristotle’s Metaphysics his educational perspective rejects mere utilitarian empiricism and the uncritical use of automated technological tools. Moncayo holds that a person who possesses only experience knows what happens, but the true scientist and engineer must know why phenomena occur and understand their ultimate cause. For him, higher education cannot be reduced to repeating technical recipes or accumulating superficial data; it must seek a deep understanding of the causal principles governing nature and structures.

2. Education as Intellectual Ascent and Civic Responsibility (Platonic Roots): From a perspective grounded in the conceptual rigor of classical academia, he conceives university education as a space for emancipating critical judgment from the superficiality of its surroundings. Technical instruction must be inseparably linked to virtue and the moral duty to protect society.

3. Science as a Moral Duty and Altruistic Service: His educational and professional philosophy holds that advanced knowledge is neither a commercial privilege nor a sterile end, but an unavoidable ethical commitment to safeguard human life and reduce the structural vulnerability of communities.
