My teaching interests are primarily in the areas of compact modeling, reliability physics and circuit design.
Whenever two objects made of dissimilar materials are brought into contact and then separated, there is a net exchange of charge. Thus, in the world around us, different objects may be at different electrostatic potentials, and electrostatic discharge events are a normal and frequent occurrence. Electrostatic discharge (ESD) is a major reliability hazard for integrated circuits; approximately 60% of silicon IC failures are attributed to electrical overstress (EOS) and electrostatic discharge. My research focuses on ESD-aware design of high-performance systems. ESD protection devices generally degrade performance, but high yield and high reliability cannot be achieved without ESD protection. By starting the design process with an awareness of BOTH performance and reliability specifications, an overall acceptable design can be formulated.
Graduate Research Opportunities
Research opportunities exist for students with interests in device physics, circuit design and electromagnetics. Students must have good communication skills and an electrical engineering background.
Undergraduate Research Opportunities
We occasionally have opportunities for undergraduate students to assist with laboratory automation or IC layout.
