In addition to the current research programs listed above, I am also interested in disturbance ecology, the role of humans in the development of historic and current forests, the evolution of landscapes and their corresponding vegetative communities, and the role of natural resource technology transfer in education and professional development. I have long been fascinated by the role people played in the development of forests. This includes prehistoric peoples, the historic lumbering period, and more recent management practices and trends. I am particularly interested in how human impacts have shaped the structure, composition, and function of our forests, and how we can adapt knowledge of past forest communities to help shape and improve contemporary silvicultural practices. One specific example of the evolution of landscapes is the formation of "prairie mounds" in the Midsouth. These natural-origin circular mounds are very abundant across much of the region, but we still know almost nothing about them. Evidence suggests they may be relicts of prehistoric climate extremes (primarily megadroughts), but we lack convincing information to definitively show that this was the origin of these features. I'm also intrigued by the seismic history of this portion of the US, especially as it relates to the formation of sand blows, a liquefaction feature found in a surprising number of areas in a previously thought stable area.
