Research Interests

• Coercing Simulations (multi-resolution modeling, composing simulations, reusing simulations, coercible software domains)

            We (Prof Dave Brogan and I and a great team of students - Prof Brogan is second from the right) are currently funded by a National Science Foundation ITR grant to investigate adapting simulations under the DDDAS program.   Requirements for simulations often change, both while the simulations are sitting on the shelf awaiting a next use, and while they're executing.  After multiple successes with adapting (we call it "coercing" )  simulations to meet new requirements, using a semi-automated approach involving optimization, we are convinced that our success in that endeavor can be enhanced significantly by technologies that support coercion from the outset -when a simulation is first designed and implemented.  Coercible simulations addresses the issues associated with early design, and downstream use.  Learn more about our COERCE research program and our modeling and simulation technology initiative.

• Reading in the Dark (interactive presentation technologies for the blind).

            We call our project "Nancy's Pantry", named after our dear friend Nancy, who has a strong desire to overcome her visual impairment in order to read menus, labels on canned goods, utility bills, labels on her clothing and so much more.  We have implemented a a prototype design using 2D barcodes, a laser scanner, an XML structure for describing menus, labels and the like, a preference based browser running on a laptop and computer based text-to-speech.  Our goal is to port this technology to a PDA.  Alternatives to barcodes include RFID, given the expected rapid proliferation of that technology.  We expect the total cost of our target device will be under $350, far below the exorbitant cost of  typical assistive technologies for the blind.

Personal

• Wife:  Craig.  Here's a picture of her.
• Kids:  Patrick, Jeffrey and Catherine (Jeff's graduation from Indiana U., May 2003;  Catherine's graduation from W&M, May 2005).
• My hobbies include:  Sailing, operating model trains, woodworking, kayaking.
• I make my own lumber now.
• One of the best photos I've ever taken.
• Some things, like real maple donuts the third weekend in March in Monterrey VA, are not to be denied.
