Professor Aya Hagishima's research lab specializes in plant-environment interactions, with a focus on transpiration dynamics and microclimate regulation in urban and controlled greenery systems. Her work explores how spatial arrangement and plant density influence water use efficiency and evapotranspiration rates in potted plants, contributing to sustainable urban greening and climate-resilient design. The lab integrates field experiments with statistical modeling to optimize plant placement for environmental benefits. Current research also examines soil moisture management and its impact on plant water relations under varying density conditions.

Abstract The effect of pot plant density on plant transpiration rate was examined in a series of field experiments. Three spatial densities were created using 203 nearly homogeneous pot plants; the ratios of plant separation to plant height were 0·25, 0·5, and 3 for the ‘high,’ ‘medium,’ and ‘low’ groups respectively. The daily transpiration rate of 55 pot plants was measured for 28 days. During that period, the plants were randomly rotated each day to statistically eliminate individual characte
