Research Statement
Plants respond to, and affect, their atmospheric
environment. Our laboratory uses integrated measurements obtained at single leaf,
single plant, and canopy scales to study these interactions, physiological responses of plants
to light and humidity influence, responses to oxidant air pollutants such as
ozone. We are currently focusing on effects of
ozone on carbon allocation and distribution of hydraulic conductance between
root and shoot, on photosynthetic inhibition by ozone, on canopy uptake
of ozone from the atmosphere, and on revegetation to reduce emissions of particulate matter
from disturbed desert soils. Experimental systems are drawn from San Joaquin Valley crop species, and from native
vegetation of surrounding arid and semi-arid areas.
