I am interested in many things, but life is short! My research has involved the orbital, rotational and volcanic histories of the moons of the solar system, the formation of the solar system, planetary ring dynamics, computer modeling of the human-made population of debris in orbit about the earth, and the rotational and orbital history of the earth-moon system as recorded in the geologic record. Links to pages describing these topics will be added as time permits (this is a very preliminary website). I was a finalist in NASA’s astronaut selection program, I am an asteroid discoverer (I got lucky -- that's the kind of good fortune that happens if you get to work with Gene Shoemaker!), and an inventor of some peculiar robotic devices. More recently, my research has involved computational neuroscience and brain-machine interfaces, and this interest has inspired the creation of robotic arms actuated by simulated muscles, and the Drury University Holodeck, which are components of the Drury University Muscle Systems Simulation Laboratory. I am a consultant for NASA's orbital debris program. I also continue to lead groups of students in experiments aboard NASA's reduced gravity "Weightless Wonder" aircraft.
I find issues regarding the interface between science and religion fascinating, and have taught a few classes on such topics. In the Fall of 2009, I participated in a debate between theists and atheists at the Skepticon II conference at Missouri State University. The entire debate can now be watched on Youtube. I have put a few thoughts regarding science and the Christian faith on a page here.

This website is under construction, but I have begun to create some pages that refer to some of my work. Most of these areas represent topics that I am either still actively involved in, or which I would like to continue to pursue, given the required available time.
