  • Muons Imaging - imaging material via naturally occurring muons
  • Biomimetics - Modeling the L4 Neuron of the Fly (Musca Domestica) Vision System, project to develop a parallel, analog electronics-based vision system.   (WYO Article
  • Funded by the National Science Foundation's Division of Bioengineering and Environmental Systems to establish a program to assist individuals with disabilities.  The purpose of the program is to provide a meaningful design experience for University of Wyoming, College of Engineering students that will directly aid individuals with disabilities in the state of Wyoming.
  • Retinal photocoagulation system for the clinical treatment of retinal disorders (i.e. diabetic retinopathy, retinal tears).  The computer-assisted system under development can rapidly tears).  The computer-assisted system under development can rapidly and safely place multiple therapeutic lesions at desired locations on the retina in a matter of seconds.  Separate low-speed prototype subsystems have been developed to control lesion depth dynamically during irradiation and to control lesion placement while compensating for retinal movement. 
  • Embedded Controllers - Wall Following Robot.  This project concentrates on using the Motorola HC12 embedded controller to guide a Wall Following Robot through an unknown maze.  The robot navigates through an unknown maze detecting walls using infra-red sensors and "land mines" (magnets) in the maze floor.  This project will be used as a class laboratory project in an embedded controller class to teach complex embedded systems concepts.
