Research

Dr. Jones’ research interests are broadly in the area of computer architecture.  In particular, his is active in the development of quantum computing.  Recently he has been investigating quantum system codesign including design of basis gates, topologies, and transpilation from resonator devices to systems.  He is also investigating emerging devices for classical computing.  For instance, he is actively developing nanoscale magnetic memory systems including spin-transfer-torque and Racetrack memories with an emphasis on processing in memory. He is well known for advancing the field of sustainable computing with full lifecycle carbon modeling and optimization and his other interests include reliability and fault-tolerance, computing and memories in harsh environments such as space, and compilation techniques for configurable systems and architectures, among others.  He has more than 200 publications in these areas.  His research is funded by NSF, DARPA, NSA, ARO, LPS, foundations, and industry.  Dr. Jones is a Fellow of the IEEE.
