Research

Dr. Khoddamzadeh’s Conservation and Sustainable (C&S) Horticulture Lab focuses on integrating practical, science-based solutions with stakeholder needs to address challenges related to abiotic stressors, species endangerment, adaptation, and environmental pollution.

This multidisciplinary research encompasses:

a) Seed technology, mycorrhizal fungi in urban environments, and in-vitro propagation (tissue culture);
b) Gene banking (cryopreservation) and synthetic seed production;
c) Applications of optical sensor technology for monitoring fertilizers, water usage, and abiotic stressors, such as salinity and heat, affecting plant health in horticultural crops.

These research areas are critical for informing best management practices in botanic gardens, gene banks, the private sector, and the nursery production industry. The C&S Lab is also designated as a Trimble Technology Lab (TTL).
