Senior Researcher, Earth Sciences at Center for Scientific Research and Higher Education of Ensenada

Thomas Gunter Kretzschmar is a senior researcher at the Center for Scientific Research and Higher Education of Ensenada (CICESE) and has over two decades of experience in hydrogeochemistry, water resources management and thermodynamic processes in aquifers. His research focuses on the evolution of water quality, groundwater flow dynamics and sustainable management of hydrological resources. Kretzschmar has mentored more than 40 students at various academic levels and published over 45 peer-reviewed articles. He is also dedicated to promoting diversity and inclusion in geosciences and fostering young researchers' development. His areas of expertise include hydrogeochemistry, water resources management and environmental geosciences.

Kretzschmar’s research integrates hydrogeochemical and isotopic analysis to address key challenges in water resource management. His interdisciplinary studies focus on characterizing the physical-chemical properties of water through the hydrological cycle, assessing ground water recharge and evaluating aquifer sustainability. His work often combines field surveys, laboratory analyses and advanced modeling techniques to understand the interaction between geological formations and water quality. Kretzschmar is currently leading projects on water balance in semi-arid zones, including the Vallede Guadalupe Basin, integrating indigenous knowledge with scientific methodologies to promote sustainable water use and conservation.

Kretzschmar enjoys mentoring students and researchers, emphasizing critical thinking, problem-solving and interdisciplinary collaboration. He is passionate about advancing the geosciences field, enhancing scientific literacy, and contributing to sustainable environmental management.
