Biography and Research Interests

I am an M.S. student in Agricultural and Environmental Plant Science at Penn State University, advised by Dr. Heather Karsten. My research focuses on climate-smart dairy cropping systems, examining how biochar amendments influence manure nitrogen dynamics, greenhouse gas emissions (NH₃ and N₂O), crop yield, and soil health in no-till dairy cropping systems. I am broadly interested in regenerative agriculture, nutrient cycling, and sustainable agroecosystem management.

My research areas and interests include:

• Biochars for mitigating gaseous loss (NH₃ and N₂O), soil health, and crop yield
• Manure and nutrient management in no-till dairy cropping systems
• Ammonia volatilization and nitrous oxide emissions
• Sustainable agroecosystem management and nutrient cycling
