Neil Mattson

Neil Mattson is a Professor at the School of Integrative Plant Science, Horticulture Section, Cornell University. His research focuses on environmental factors and cultural practices affecting greenhouse crop physiology, nutrient management, and abiotic stress tolerance.

• Education: PhD in Horticulture (University of California Davis, 2007), MS in Horticulture (University of Minnesota, 2002), BA in Biology (University of Minnesota Morris, 2000)
• Key Research Areas: Controlled Environment Agriculture (CEA), Greenhouse Lighting and Systems Engineering, Salt Stress Physiology, Sustainable Nutrient Management

Mattson's extension work addresses greenhouse sustainability through cost reduction and environmental stewardship, particularly in New York's floriculture industry. He received the 40 Under 40 Leaders in Horticulture award (2015) and was inducted into Pi Alpha Xi honor society (2013).

His 2025-2024 research explores:

• Split-root hydroponic systems for lettuce
• Genomic responses to abiotic stress in petunia
• Plasma-activated water for sustainable nitrogen supply
• Machine learning applications for nutrient diagnostics
• UV-B radiation effects on cannabis phytochemistry

He teaches PLSCI 3025/5025 Hydroponic Food Crop Production and Management, emphasizing hands-on learning and community engagement through food donations.
