Daniel N. Donahoe, Ph.D., P.E., CRE

Managing Engineer

Electrical & Semiconductors

Professional Profile


Dr. Donahoe has 30 years of experience related to electronics integration and reliability. His electronic packaging analysis skills include thermal analysis, stress and dynamics analysis, and component failure analysis. At Exponent, Dr. Donahoe has worked on computer products, medical products, industrial equipment, consumer products, petrochemical equipment, automotive equipment, and solar energy systems. Electronics work at Exponent has included component failure analysis of components such as the printed wiring board, capacitor, inductor, diode, cold cathode fluorescent lamp, and other common components. Solution methods have included reliability analyses such as fishbone diagrams and failure modes and effects analysis (FMEA), finite element analysis (FEA), and laboratory testing. Other tasks have included intellectual property.

Prior to joining Exponent, his functional assignments included work as a design engineer, reliability engineer, thermal engineer, manager, technologist, and scientist. In military electronics, he worked on electronics exposed to extreme environments ranging from the high acceleration loads of gun launch to thermal challenges faced in life support, spacecraft, and the design of high voltage radar subsystems. In addition to electronic products exposed to exotic environments, Dr. Donahoe has worked on cost-driven commercial electronics products. His work on cooling of computer components has generated patents. In addition, Dr. Donahoe has worked on electronics into facilities, especially focusing on the design of Heating, Ventilation, and Air Conditioning (HVAC) support systems. 

Dr. Donahoe is the 2007–2008 Chair of the IEEE Components, Packaging and Manufacturing Technologies Society (CPMT) Santa Clara Valley Chapter.
