Curriculum Vitae

Extension Associate Professor

Research Interests and Projects

My research activity is mainly focused on sustainability of farming systems through diversified cropping systems. I am specifically interested in integrating cover crops into farming systems to enhance nutrient recovery and recycling, weed suppression, and improving general soil health.
