Current Research

Ecosystem level impacts of invasive grasses on Hawaiian dry forest ecosystems.

Mechanisms by which fountain grass limits Hawaiian dry forest native plant establishment and growth by manipulating fountain grass, available water, and available light separately and in concert.

Functional ecology and phenology of dry forest canopy trees.

Investigating the role that native plant reforestation plays in reducing fine fuel load hazards and reversing the cumulative adverse ecosystem level effects of monotypic stands of invasive grasses in leeward Hawaii

Impacts of invasive species on lowland forest ecosystem processes, specifically, rainfall interception, plant water use and acquisition, light availability and plant productivity.

Research Interests

Ecophysiology, Restoration Ecology, Functional Ecology, Tropical Dry Ecosystems, Grass Invasions, Hawaiian Ecosystems

Future Research
