Brad Day, Ph.D., is a professor in MSU’s Department of Plant, Soil and Microbial Sciences. Day’s research focuses on the molecular-genetic and biochemical processes associated with the interaction between plants and pathogens. Specifically, Day’s research lab is interested in how plants protect themselves from pathogen infection.

Day received his Ph.D. from the University of Tennessee in Microbiology in 1999 where his research focused on biochemical characterization of NOD signal perception in soybean. Prior to his role at MSU, Day served as an NIH-funded postdoc at the University of California-Berkeley.

In 2006, he accepted a position at MSU as an assistant professor. Since 2006, his lab has worked to define the role of the actin cytoskeleton as a signaling platform for immune signaling in plants. His group was the first to identify a link between the function of the actin cytoskeleton and gene-for-gene resistance. In 2017, he was promoted to professor at MSU.

Day served as the associate chair for Research in the Department of Plant, Soil and Microbial Sciences. He is a member of the MSU Plant Resilience Institute. Day recently received a nearly $1 million grant from the National Science Foundation (NSF) to extend his study on how plants, at the cellular level, respond to disease threats.

Research in Day’s lab is supported by The College of Agriculture and Natural Resources (CANR), the Office of the Vice President for Research and Graduate Studies (OVPRGS), the National Science Foundation, the National Institutes of Health (NIGMS) and the United States Department of Agriculture (NIFA).
