Dr. Mitra's research interests include robust system design, VLSI design, CAD, validation and test, and emerging nanotechnologies.  His X-Compact technique for test compression has been key to cost-effective manufacturing and high-quality testing of a vast majority of electronic systems, including numerous Intel products. X-Compact and its derivatives have been implemented in widely-used commercial Electronic Design Automation tools.  The QED and IFRA techniques, created jointly with his students, have shown outstanding results in overcoming critical bottlenecks in post-silicon validation and debug for several commercial hardware platforms, and have been characterized as "breakthrough" in a Research Highlight in the Communications of the ACM (CACM). His work on carbon nanotube imperfection-immune digital VLSI, jointly with his students and collaborators, resulted in the demonstration of the first carbon nanotube computer, and it was featured on the cover of NATURE. The National Science Foundation (NSF) presented this work as a Research Highlight to the United States Congress, and it also was highlighted as "an important, scientific breakthrough" by the BBC, Economist, EE Times, IEEE Spectrum, MIT Technology Review, New York Times, Scientific American, Time, Wall Street Journal, Washington Post, and numerous other organizations worldwide.
