Project summaries
For more information about any of these projects, please contact Professor G.-P. Li or Professor Mark Bachman. Most of these projects have yielded (or will yield) results that are suitable for follow-on activity in further research or development. Furthermore, many of the projects yield excellent IP in the form of inventions or special methods. It is a policy in the Li/Bachman laboratory to consider, to the extent possible, market insertion issues when designing new processes or devices. These include issues such as manufacturability, cost, usability, and appropriateness of the solution to the application.
