In addition to the operation of the Instrumentation Design Laboratory, work in several other areas of interest is being pursued. A current project is to reduce table-top instruments to the size that a rat or other animal subject can carry on its back. Projects of this type have multiple dimensions: new low- power design capabilities, new construction techniques, and new software design methods to name a few.

In the field of education, a need remains for techniques for teaching about instrumentation. Students need to be exposed to the concepts of electronic, computer-aided instruments without the burden of an engineering course, all the while dealing with the concepts accurately. Tools for lab-based study are being developed with support from the Dreyfus Foundation.
