Ripley Tisdale

Ripley Tisdale serves as a USDA Assistant Professor and Plant Physiologist at the USDA-ARS Plant Science Research Building in Raleigh, North Carolina, affiliated with North Carolina State University. Her research addresses critical threats to global food security posed by tropospheric ozone pollution and rising temperatures under climate change.

Her research program focuses on:

• Mechanisms of plant responses to combined ozone and heat stress
• Development of climate-resilient crops through field-based climate change systems
• Molecular and biochemical regulation of stress responses via multi-omic approaches
• Root-soil microbe interactions under environmental stressors
• Carbon-nitrogen allocation dynamics in agricultural ecosystems

Analysis of her 2020-2023 publications reveals consistent investigation of soybean and wheat responses to ozone-heat interactions. Her work demonstrates ozone's rapid suppression of root growth, genotype-specific proteome changes, and impacts on yield and nutrient content. Key methodologies include field-based climate simulation systems and multi-omics integration to bridge molecular mechanisms with physiological outcomes.

Dr. Tisdale leads research utilizing the Field-based Climate Change System and collaborates extensively with scientists including Burkey, Zentella, and Zobel. Her work provides foundational knowledge for developing agricultural solutions to climate-air pollution synergies threatening crop productivity worldwide.
