Carolina Gomez is a seasoned geologist with over 20 years of experience in sedimentary basin analysis, specializing in fluid exploration in clastic, evaporite an fractured rock reservoirs/aquifers. She has a proven ability to leverage this expertise in both exploration and environmental projects. Carolina has developed geological models and hydrogeological conceptual models for natural and built systems, such as mining facilities. Working as a technical team leader, she has developed strong interaction with different knowledge areas in the engineering, earth sciences and social fields. For the past nine years, her focus has shifted towards environmental risk assessment and mine closure. Her leadership in this area is evident in her work for the National Water Agency, where she independently consulted on environmental report revisions. She has also worked on water collaborative governance. This experience honed her skills in stakeholder engagement and ensuring compliance with environmental regulations. Over the last two years, her expertise is dedicated to the Salar de Atacama's hydrogeology and environmental strategy.
