Marcus Gary

Marcus Gary is a Research Associate Professor at the Bureau of Economic Geology, Jackson School of Geosciences, The University of Texas at Austin, and Principal Geoscientist at the Edwards Aquifer Authority. His expertise lies in karst hydrogeology, focusing on karst processes and their implications for natural resource management. He holds a Ph.D. in Hydrogeology (UT Austin, 2009) and a B.S. from the same institution (2001). His doctoral work on Sistema Zacatón, a deep underwater cave system in Mexico, integrated geophysics, geochemistry, and NASA-funded DEPTHX AUV technology to map cave structures.

• Education:
  • Ph.D. in Hydrogeology, UT Austin (2009)
  • B.S., UT Austin (2001)
  • A.S. in Marine Technology, College of Oceaneering (1994)
• Research Interests:
  • Karst aquifer dynamics
  • Groundwater-surface water interactions
  • Volcanogenic speleogenesis
  • Edwards and Trinity Aquifer management
  • Geophysical and geospatial techniques in hydrogeology

His work spans academic research, government service (USGS), and consulting. He teaches Applied Karst Hydrogeology at UT Austin and leads field operations for the Edwards Aquifer Authority. Notable projects include dye tracing studies in Central Texas, springhead delineation, and volcanic influences on karst systems. His research often emphasizes environmental policy and sustainable groundwater management.
