Research Areas:
The mission of our research is to identify and characterize physiological and biochemical mechanisms influencing growth and stress tolerance of plant species used for livestock feed and biofuels.
 
Four research topics are currently being examined in detail.


Characterize mechanisms controlling synthesis and degradation of organic reserves (starches, sugars, and storage proteins) in storage organs, and understand the role of organic reserves in plant growth and stress tolerance.

Conduct comparative analysis of water and nitrogen use by candidate biofuels species. These analyses aim to identify those species and cropping systems that maximize production of cellulose, hemicellulose, and nonstructural carbohydrates while minimizing environmental impacts.

Determine the physiological, ecological and molecular mechanisms controlling abiotic stress tolerance of plants.

Understand water and nutrient use efficiencies in crop plants  and the underlying physiological, ecological and biochemical drivers of these traits.

Extension:
The goal of extension work is to provide the public with information on yield, quality, and persistence of perennial plants used for forage or biomass, especially as influenced by management and genetics.
