Research program: 

The long-term goal of my research program is to support the continued growth and long-term sustainability of local food systems by helping specialty crop growers improve the productivity, quality, and safety of their crops while improving and protecting environmental health. To accomplish the goal, my lab studies soil microbial ecology. Soil microbial communities regulate many key agroecosystem services including carbon sequestration, nutrient and heavy metal cycling, pollutant detoxification and pathogen suppression. Some soil microbes can also interact closely with plants to help them acquire resources, withstand biotic and abiotic stress, and improve the nutritional quality and safety of produce. Consequently, by identifying mechanisms mediating the evolution, composition and activity of beneficial plant-soil-microbial relationships, we can identify new, more sustainable approaches to deal with crop production challenges and ensure the long-term success of local food systems. 

Additional insights about my research, teaching and engagement program and introductions to all the great people contributing to these efforts can be found on the Hoagland Lab Website: www.purdue.edu/hla/sites/hoaglandlab.
