Statement
During summers, I spend much of my time at the Cedar
Creek Natural History Area, helping manage all the bustling research and
other human activity that goes on there. The beginning of the twenty-first century
is crucial for future planning, to keep the diverse natural habitats of Cedar
Creek wild in the midst of an emerging suburban landscape. There are exciting
opportunities at Cedar Creek to participate in harmonious co-planning with local
communities and governments.
During winters, I turn to theoretical ecology -- effects of biodiversity on stability and other ecosystem properties, simplified models of ecosystem operation, ecology's interface with evolutionary theory. More generally, I am fascinated by computer applications to biology where computation is not only the tool, but the very paradigm for understanding the biological system. This includes application of artificial neural networks to problems of animal behavior, application of computer state-space searching concepts to evolution in complex fitness landscapes, and other interesting things.
I also conduct several well-replicated field experiments that are part of an adaptive management strategy for my own native prairie and savanna restorations.
