Expert Witness #263678

This expert has many years of experience in materials science and engineering. This expert is a Professor of Materials Science & Engineering. Much of this expert's work has involved formulating materials for enhanced electrical and electromechanical response with associated experience in spectroscopy. According to this expert, in nearly all ceramic compositions, the enhanced response results from functional dopants or dopant pairs that also cause ancillary, i.e., non-performance critical, changes in properties. Color changes are a quite common outcome of dopants that were added for a key, non-color, functional purpose. This is the situation for the electroactive materials of this expert's research, e.g., PMN, PZT and oxynitrides, and also for the dielectric materials (alumina) emphasized in university courses.

One of this expert's courses addressed the causes of color in glasses and ceramics. A hands-on illustration, also used in long-running courses, was the progressive reddening of alumina with increasing levels of chrome associated with enhanced mechanical response. One of this expert's courses addressed bio-implantable devices, e.g., hip-implants and defibrillators. In addition to technical expertise, this expert has both deposition and trial experience.

This expert holds a PhD in Solid State Engineering and a BS in Polymer Science, and Coursework to achieve a Chemistry Educator Certification.
