Dr. Preethi Vijayaraghavareddy
Research Quest
Research Interests
- She investigates the physiological, molecular, and chemical-genomic bases of plant adaptation to abiotic stresses.
Research themes include
- Nocturnal and pre-dawn transpiration: physiological and molecular mechanisms determining water-use efficiency and carbon assimilation
- Stomatal kinetics, ROS homeostasis, and circadian regulation
- Phenotyping, metabolomics, and genome-wide association studies (GWAS) for stress-adaptive traits
- Chemical genomics for improving crop productivity and resilience
- Trait-based precision breeding and sustainable agriculture for climate change adaptation
Academic Bio
Dr. Preethi obtained her Ph.D. in Crop Physiology from Wageningen University and Research, The Netherlands, and her M.Sc. in Crop Physiology from the University of Agricultural Sciences, Bangalore, India. Following her doctoral studies, she served as a DST-INSPIRE Faculty Scientist at University of Agricultural Sciences, Bangalore, where she established an independent research program on nocturnal transpiration and water-use efficiency in rice.
Her research bridges basic plant science and applied agricultural innovation, focusing on the physiological and molecular dissection of traits that enhance drought adaptation and water productivity. Through her work, Dr. Vijayaraghavareddy aims to develop climate-resilient and water-efficient crops using both physiological and molecular insights.
