Dr. Graham began at Tech in 2003 as an Assistant Professor. Prior, he was a Senior Member of the Technical Staff at Sandia National Laboratories in Livermore, California.


Dr. Graham's research focuses on the fabrication, packaging, and reliability of electronic devices.  In this work, his group has expertise in the thermal analysis and reliability of GaN based wide bandgap semiconductors used in RF communications, solid state lighting, and power electronics.  His group develops experimental techniques to measure the temperature and stress distribution in these devices down to the individual transistor level.  In addition, they investigate the thermophysical properties and thermal interface resistance between the active layers and substrates such as SiC, Si, and diamond.  Coupled electro-thermal and thermomechanical modeling of these devices are used under both DC and transient timescales to understand the performance of these devices.  Finally, methods to effective remove the heat from these devices using single phase and two phase cooling are under investigation.

In addition to wide bandgap devices, the Graham group is also working on packaging and reliability of organic electronics and thin film solar cells.  His group has developed expertise in the creation of ultra-barrier film technology based on vacuum deposited thin films for the hermetic sealing of electronics.  The mass transport along with the mechanics of the films (fracture, adhesion, etc.) and chemical resistance is important for the fabrication of thin film and flexible electronics for harsh environments.  The Graham group regularly collaborates with the Center for Organic Photonics and Electronics in this area of research (
