Research Interests

I have studied the production, protection and sustainable management of bottomland hardwoods for more than 20 years. In addition to my research and development of biofuels feedstock crop production systems for eastern cottonwood and black willow, I and my cooperators are developing disease resistance in American sycamore to be grown in plantations for pulpwood, biofuels feedstocks, and other natural products. I helped refine and promote the use of an eastern cottonwood-oak interplanting method developed by the Center for Bottomland Hardwoods Research to the point where the method has been used from 2007 to 2014 to plant more than 12 million hardwood trees on nearly 20,000 acres of formerly unproductive agricultural land in the Mississippi Alluvial Valley.
