Connecting Science, Policy, and People to Conserve Coral Reefs and Ocean Health

About me

About me image
I am a marine biologist and policy advisor with over 15 years of experience in coral reef research, symbiosis, and ecosystem restoration. My academic training in Colombia, Mexico, and the U.S. has shaped an interdisciplinary approach that connects scientific research with environmental governance. As a delegate of Colombia’s Ministry of Environment, I have contributed to high-level international forums, helping advance marine resilience strategies across Colombia and Latin America. I am strongly committed to cross-sector collaboration as a means to strengthen scientific knowledge, guide conservation efforts, and promote the sustainable management of coastal ecosystems.

Research and Policy Impact

Coral Reef Science & Restoration

Coral Reef Science & Restoration

My research explores the ecological and physiological foundations of coral reef resilience, with a focus on coral photobiology, symbiosis, and environmental adaptation. I study how tropical corals respond to light availability, water quality, and habitat structure across biological scales—from individual colonies to populations and communities. By combining bio-optical modeling, fieldwork, and laboratory experimentation, I investigate the drivers of niche partitioning, biodiversity patterns, and coral reef degradation. This scientific foundation directly informs the design of evidence-based restoration strategies, including Colombia’s National Coral Reef Restoration Program (PNRACC), where I help bridge ecological science, public policy, and community-led action to support the recovery of coral reef ecosystems.

Science–Policy Interface

Science–Policy Interface

I work at the intersection of science and environmental governance, translating research on coral reef ecology into actionable policies and technical guidance. As a technical advisor to Colombia’s Ministry of Environment, I contribute to national restoration planning, inter-institutional coordination, and the development of protocols to address emerging threats such as stony coral tissue loss disease (SCTLD). My work includes the synthesis of scientific evidence to inform decision-making, the design of policy instruments grounded in ecological function, and active participation in multi-stakeholder platforms that shape marine conservation strategies at the national and regional levels.

International Engagement

International Engagement

I actively participate in international cooperation and ocean diplomacy, representing Colombia in global forums focused on marine conservation and climate action. My engagement spans multilateral platforms such as the UN Biodiversity Conference (COP16), the UN Ocean Conference (UNOC3), and the UN Framework Convention on Climate Change (UNFCCC). I have organized and moderated high-level panels on marine ecosystem conservation, restoration, governance, and sustainable blue economy strategies—fostering collaboration among governments, scientists, and civil society. These forums serve as platforms to promote inclusive, science-based solutions to global ocean challenges.

TEACHING

TEACHING image
  • Symbiosis (BIOL 406). Lecturer. Penn State University. In this advanced course, we delved into the significance of symbiotic interactions in nature and explored the unifying concepts that transcend various forms of symbiosis and other species interactions.
  • Basic Concepts and Biodiversity (BIOL 110W). Lab TA. Penn State University. The primary focus in this course was to provide the students with the opportunity for a hands-on experience in the scientific process and to explore the incredible biological diversity of life on Earth. 
  • Population and Communities (BIOL 220W). Lab TA. Penn State University. Throughout this course, we introduced students to the fundamental principles, concepts, patterns, and processes that underpin the dynamics of populations, communities, and ecosystems.
  • Light and Photosynthesis Workshop. Instructor. UNAM and Penn State University. For nearly two decades, this international workshop has explored the effects of light on photosynthesis, energy dynamics, and the adaptive strategies of marine organisms.
