Saijaliisa Kangasjärvi is an Associate Professor at the University of Helsinki's Faculty of Biological and Environmental Sciences , leading the Crop Light research group within the Organismal and Evolutionary Biology Research Programme . Her work bridges plant light signaling, stress tolerance, and metabolic regulation to enhance vegetable quality in indoor cultivation. Research Focus: Mitochondrial dysfunction responses, light stress signaling pathways, and post-harvest quality optimization in leafy greens through metabolomics and proteomics. Key Contributions: Identification of PP2A-B'γ as a central regulator of stress-induced ROS signaling, glucosinolate biosynthesis, and genotype-specific metabolic responses in kale. Leadership: Director of the Master’s Programme in Integrative Plant Science (2021-2024), active in editorial roles for Journal of Experimental Botany and New Phytologist . Article Trends: Recent studies emphasize dynamic lighting in controlled farming, post-harvest metabolic shifts in lettuce, and mitochondrial-chloroplast signaling networks under stress. Her 2025 work explores energy-efficient LED applications and translational photobiology for flavor-nutrition optimization in leafy vegetables. Supervision: Mentors doctoral candidates including Maria Waldén and Arttu Mäkinen, with a focus on stress-induced metabolic regulation and indoor cultivation techniques.
