Dr. Gowda serves as a supervisory soil scientist for the Forage and Livestock Production Research Unit at the USDA-ARS Grazinglands Research Laboratory El Reno, OK. He conducts research in forage and rangeland management, remote sensing, water resources management, and greenhouse gas emissions in the Southern Great Plains. Specific research areas include, but are not limited to: greenhouse gas monitoring and modeling, regional evapotranspiration (ET) mapping, eddy covariance, and hydrologic and crop modeling.

Current research projects include crop modeling with DSSAT, development of UAV remote sensing based grazing management tools, developing and managing a network of greenhouse measurement systems, ET-SWAT-MODFLOW linkage for groundwater management, development and evaluation of remote sensing based surface energy balance models, energy balance closure problem with eddy covariance systems, development of ET mapping and reference ET software for operational ET remote sensing programs and irrigation scheduling, calibration and validation of hydrologic and crop models and revising their irrigation and yield estimation algorithms, and application of ET, hydrologic and crop models for developing and evaluating agricultural management practices that are resilient to climate extremes.
