# Arthur Frank Witulski

Arthur Frank Witulski is an American electrical engineer. He is the Research Associate Professor Electrical Engineering and Computer Science at Vanderbilt University, where his research activities focus on microelectronics and semiconductor devices. He is affiliated with the Radiation Effects and Reliability Group at Vanderbilt University, where he works on the effects of radiation on semiconductor devices and integrated circuits. He also serves as an engineer at the Institute for Space and Defense Electronics at Vanderbilt. He is best known for his work in the field of Power electronics and ionizing radiation response of DC-to-DC converter.

## Early life and education

Witulski completed his high school in 1977 and joined the University of Colorado at Boulder for his BS degree. After graduating in 1981, he joined Storage Technology Corporation.

## Career
### University of Arizona

After graduating in 1989, he joined the University of Arizona in 1989 as an assistant professor of Electrical Engineering. He rose through the ranks and became an associate professor when he left the university in 2000.

### Return to Academia - Vanderbilt University

In 2003, following a few other professors such as Ron Schrimpf, Witulski moved to Vanderbilt University, Nashville, Tennessee. Along with Kenneth Galloway and Shera Kerns, they established the Radiation Effects and Reliability Group at Vanderbilt, which is now the largest of its type at any US University.
