Justin William Walley

Justin William Walley is a Professor in the Department of Plant Pathology, Entomology and Microbiology at Iowa State University, with a courtesy appointment in Chemistry. He holds a Ph.D. from UC Davis (2009) and leads research on molecular mechanisms in plant growth and stress responses using mass spectrometry-based proteomics and systems biology.

Research integrates multi-omics approaches to study protein post-translational modifications (ubiquitination, phosphorylation, acetylation) and their roles in signal transduction, autophagy, and environmental adaptation. Recent NSF-funded projects examine transcription factor networks, brassinosteroid-TOR signaling crosstalk, and disease resistance architecture in maize.

Publications demonstrate advanced proteomic methodologies including TurboID proximity labeling, single-cell proteomics, and super-resolution ribosome profiling. Work consistently links regulatory networks to phenotypic outcomes in development and stress responses.
