Grasser's research interests are focused on numerical simulation of solid-state devices and integrated circuits.
For contributions to the modeling of the reliability of semiconductor devices, he was named a Fellow of the Institute of Electrical and Electronics Engineers (IEEE) in 2016.
Presently, beyond administrative functioning, Grasser is a professor of microelectronics specializing in simulation aspects and reliability issues.
He serves/served as an Associate Editor for the IEEE Transactions on Electron Devices and Microelectronics Reliability (Elsevier) and is involved in organization of various outstanding conferences such as IEDM.
