Research / Research Programs

Raghavan Srinivasan (Ph.D., Purdue University), is the current Director for the Blackland Research and Extension Center and the Director of the Spatial Sciences Laboratory at Texas A& M University. Dr. Srinivasan is most well-known for his leadership and cooperation with USDA scientists in the development, dissemination, and use of the Soil and Water Assessment Tool (SWAT). Dr. Srinivasan is the internationally recognized leader in making SWAT the world’s most widely used and frequently cited watershed-scale hydrology and water quality model over the last 25 years.

Agro-Ecosystem Analysis and Computer Modeling

  • Jay Angerer (Ph.D., Texas A & M University) develops and applies computer models and decision support systems to improve management, productivity, and sustainability of pasture and grazing lands in the USA and developing countries.
  • William E. “Bill” Fox III (Ph.D., Texas A & M University) conducts research on restoring disturbed agricultural and natural ecosystems.  Identifies best management practices to ameliorate impairments or mitigate unintended consequences of agriculture.
  • Manyowa Norman Meki (Ph.D., University of Cambridge, UK) uses biophysical models to evaluate best management practices and assess environmental impacts of potential grain, biomass, and oilseed cropping systems.
  • Cody Zilverberg (Ph.D., Texas Tech University), develops computer models to improve management, productivity, and sustainability of pasture and grazing lands.

Hydrologic Systems Computer Modeling

  • Katrin Bieger (Ph.D., University of Kiel, Germany) develops and applies hydrologic computer models to evaluate the impacts of land use and agricultural management on water resources.
  • Jaehak Jeong (Ph.D., University of Texas) develops and applies hydrologic computer models to evaluate the impact of management on urban, agricultural, and natural landscapes.
  • Javier Osorio Leyton (Ph.D., Virginia Tech) develops and calibrates SWAT model to assess feasibility of biofuel feedstock production in Hawaii under different climatic/environmental/management situations; develops and tests SWAT routines for locally prevalent hydrological processes in Hawaii; and integrates a farm scale SWAT irrigation support model (under development) to the calibrated whole island SWAT model and conducts scenario runs.
  • Luca Doro (Ph.D., University of Sassari, Italy) collaborates with the modeling team led by Dr. Lee Norfleet (US Natural Resources Conservation Service) to build a database that includes general and crop parameters for regional model calibration. Provides support in simulation output analysis and collaborates in the development of the EPIC and APEX model.
  • Xiuying (Susan) Wang (Ph.D., Purdue University) conducts hydrologic and environmental research to assess the impacts of agricultural and natural resource systems.  Develops, tests, and improves agriculture and natural resource computer simulation models.
  • Jimmy Williams (Ph.D., Texas A&M University) develops and applies computer modeling technology to evaluate impacts of management practices on watersheds and impacts of on-farm management decisions on environmental quality.
  • Haw Yen (Ph.D., Colorado State University) designs and develops watershed simulations to mitigate environmental and ecological impacts for the new version of the Soil and Water Assessment Tool (SWAT).
  • Abeyou Worqlul (Ph.D., Cornell University) applies hydrologic computer models to assess the impact of land use, climate change, and management on watersheds systems. Currently working with the ILSSI (Innovation Lab for Small-Scale Irrigation) project.
  • Tadesse Abitew (Ph.D., Vrije Universiteit Brussel, Belgium) develops and applies hydrologic and remote sensing-based energy balance models to evaluate the impacts of land use and management practices on water resources at multiple landscape scale. Currently he is contributing to a US Dept. of the Interior, Bureau of Land Management (BLM) funded project on soil erosion and salt transport modeling in rangelands.
  • Jungang Gao (Ph.D., Graduate University of the Chinese Academy of Sciences, China) develops and applies hydrologic models from the field to the national scale to assess the impacts of conservation practices on water resources.
  • Seonggyu Park (Ph.D., Colorado State University) is interested in the development of hydrologic models for identifying present and future water resources management. He specializes in assessing spatial-temporal patterns of interactions between groundwater and surface water using a coupled SWAT-MODFLOW model and optimizing SWAT and MODFLOW linkage.

Spatial Science and Integrated Information Systems

  • Cesar Izzurralde (Ph.D., Kansas State University) develops robust modeling methods for evaluating the impacts of climate change on terrestrial ecosystems and water resources. His research also examines mitigation options in agriculture and energy through soil carbon sequestration, greenhouse gas emission reductions, and the sustainable production of biofuels.

Water Science – Quality and Monitoring

  • June Wolfe (Ph.D., Baylor University) conducts hydrology and water quality field research and monitoring by examining the impacts of land management on bacteria, nutrient, and sediment accumulation and transformation in streams.
  • Anish Jantrania (Ph.D., Clemson University) develops innovative and affordable solutions for sustainable water, wastewater, and solid waste treatment processes.
