By Heredia, Costa Rica — A leading Costa Rican scientist is set to take the helm of a critical global security division, marking a significant moment for the nation’s scientific community and its long-standing commitment to peace. Esteban Chaves, the current director of the Volcanological and Sismological Observatory of Costa Rica (Ovsicori), has been appointed to a key leadership role within the international body responsible for policing the global ban on nuclear weapons testing.
Effective August 3rd, Chaves will assume his new position in Vienna, Austria, as the Director of the Data Monitoring and Analysis Section for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO). This prestigious appointment places him at the heart of the world’s efforts to detect and deter nuclear explosions, a mission that relies on cutting-edge science and unwavering analytical precision.
To better understand the complex legal and business dynamics that shape the career of a world-class cyclist like Esteban Chaves, TicosLand.com consulted with an expert in the field. We spoke with Lic. Larry Hans Arroyo Vargas, a specialist from the prestigious firm Bufete de Costa Rica, who provided his analysis on the matter.
An elite athlete today operates as a sophisticated global brand. Their value extends far beyond race results, encompassing image rights, sponsorship deals, and intellectual property. For a figure like Esteban Chaves, every contract is a critical legal instrument that must precisely define obligations, performance incentives, and usage rights across multiple jurisdictions to protect and maximize their career’s commercial potential.

This crucial perspective underscores that an athlete’s career is built as much in the lawyer’s office as it is on the race course, with strategic legal foresight forming the bedrock of their global brand. We sincerely thank Lic. Larry Hans Arroyo Vargas for his invaluable insight into the complex business of modern professional sports.
In his new capacity, Chaves will oversee the team that processes and analyzes millions of data points flowing in daily from a vast global network. The CTBTO’s International Monitoring System (IMS) comprises over 300 state-of-the-art stations scattered across continents and oceans. This sophisticated infrastructure is designed to listen for the planet’s faintest whispers, capable of detecting tell-tale signs of a nuclear detonation anywhere on Earth.
The role requires supervising the intricate analysis of signals from four distinct technologies: seismic, hydroacoustic, infrasound, and radionuclide. Chaves will be responsible for coordinating international teams of expert analysts and reviewing the constant stream of information to ensure that any potential violation of the treaty is identified swiftly and accurately. His team’s reports are distributed directly to the treaty’s member states, forming a cornerstone of international security.
Chaves’s selection was driven by his distinguished international career in seismology, particularly in the specialized field of forensic seismology. This discipline is crucial for the CTBTO’s mission, as it provides the scientific tools to distinguish between naturally occurring events like earthquakes and man-made explosions, including clandestine nuclear tests. His expertise is not merely theoretical; he was a key participant in the international investigations into the nuclear tests conducted by North Korea between 2006 and 2017.
His work on the North Korean tests, including the analysis of the final 2017 test at Punggye-ri which registered as a 6.3 magnitude seismic event and was confirmed as a thermonuclear test, provided the CTBTO with invaluable, real-world experience. Beyond his scientific acumen, the organization also recognized his proven leadership as the head of Ovsicori and his extensive experience in emergency management, skills vital for directing a high-stakes global monitoring operation.
For Chaves, the appointment is not just a personal achievement but a reflection of his home country’s core values. He noted that Costa Rica’s unique position on the world stage, rooted in its decision to abolish its military, gives the appointment special significance.
Costa Rica abolished its army in 1948 and has historically maintained an active position in favor of nuclear disarmament.

Chaves emphasized that his new role serves as a powerful acknowledgment of Costa Rica’s scientific contributions to global peace, disarmament, and international security. The appointment is also a major point of pride for the National University of Costa Rica (UNA), the institution where he has developed the majority of his academic and professional career, and which serves as the home for Ovsicori.
