Research summary
AI-generated

This researcher studies environmental and engineering challenges in agricultural and waste-treatment systems, particularly air quality and odor control in livestock housing, and biogas production through anaerobic digestion of food and animal waste. Work also extends into composting processes, biofertilizer development, and monitoring technologies for animal production facilities. The research combines environmental engineering, waste management, and agricultural technology, often with applied and process-optimization goals.
