Sen Subramanian

Dr. Sen Subramanian is Professor and Dean of the College of Natural Sciences at South Dakota State University, with joint appointments in the Departments of Agronomy, Horticulture and Plant Science, and Biology and Microbiology. His research program focuses on sustainable nitrogen management through biological fixation.

Primary research areas include: 1) Hormone signaling mechanisms regulating soybean nodule development, particularly auxin-cytokinin interplay; 2) Plant microbiome optimization for enhanced nutrient uptake and disease resistance; 3) Climate-resilient nitrogen fixation via rhizobial adaptation. Recent publications (2020-2024) demonstrate strong emphasis on rhizobia-soybean interactions under abiotic stress, nanoparticle effects on symbiosis, and intercropping systems for GHG mitigation.

As senior investigator in 2DBEST (NSF EPSCoR center), he leads genomics initiatives on plant-microbe communication. Teaches graduate courses in plant genetics and serves as Gamma Sigma Delta Agriculture Honor Society president (2019). Research funded by NSF EPSCoR and agricultural commodity groups.
