Q. Tell me a little about your research area and what motivated you to get into it?

A. My research focuses on different aspects of dependable computer architectures and in particular microprocessor error detection methodologies that can be employed during manufacturing testing, during silicon validation as well as during on-line testing in the field. My main motivation in doing research around microprocessor architectures dependability was my obvious belief, as a computer engineer, in the central role of the microprocessor in the overall dependability of the computing system.

Q. What are some of your proudest accomplishments?

A. My key contribution in the field of microprocessors dependability is the development of software-based self-test methods that allow error detection for microprocessors as well as other components of microprocessor-based systems (memories, peripherals, interconnects) using only the native instruction set of the microprocessor without any hardware modifications. I guess that the breadth and efficiency of the techniques are well recognized by the community.

Q. What motivated you to become an Associate Editor for the IEEE TC?

A. For a computer engineer that continues his career in a university of research organization, joining the Editorial Board of one of the most prestigious transactions of our discipline is always a dream. My main motivation during all years of volunteer service on the Editorial Board of IEEE TC was to promote top quality research by enabling a peer review process following TC guidelines. I believe this is the only way to keep TC in the leading edge of computer engineering research.

Q. What is the best part of being an Associate Editor and will you encourage others to take up this role?

A. It is certainly the ability to take care of the review process for research work that is really mature. Conferences reviewing is exciting because you can see work in its beginning, but for top-tier journals like IEEE TC, it is really a pleasure to see works that have been prepared for quite a lot of time, very well-elaborated and fully supported by experimental campaigns. This feeling of completeness is valuable for any profession. Submitting authors to TC really do their best to deliver excellent research outcomes.

Q. How do you see your research field shaping up and what are the major directions?

A. Computing systems dependability/reliability is an area that will naturally expand a lot the next years. The underlying technologies on which computer (and other) electronics are built are quickly getting much more unreliable. I believe that the major research efforts in the area of reliability will focus on multi-layer approaches involving both hardware and software techniques so that technology scaling keeps offering us its benefits in an energy-efficient way despite the more massive effect of permanent and transient hardware defects.

Q. What advice would you give to junior researchers and graduate students?

A. Believe in computer engineering potential. There is a lot of open space for innovation in hardware and software technologies.

Q. What profession would you be in if you weren't in this field?

A. Professional soccer player!

Q. Any final thoughts?

A. Warm wishes to IEEE TC current and future Editors-in-Chief, Associate Editors, and Staff for the next decades of the leading journal of our discipline.
