My research group is focusing on developing nanoscale computing fabrics and associated models of computation (often unconventional – not von Neumann). Our current direction is on 3D nanofabrics for cognitive and microprocessor ICs (Skybridge, 3D Fine-Grained/Monolythic CMOS) and on Causal-Intelligence (Bayesian) Architectures with nanotechnology. The Bayesian approach is one of the 5 papers selected for Rebooting Computing Special Issue in IEEE Computer (Dec, 2015). Other nanofabrics initiated in my group include NASICs, Spin Wave Functions, N3ASIC, Bayesian magneto-electric directions, wave interference computing with spin devices, etc. We do occasional experimental (Cleanroom) work in addition to detailed cross-layer (device-circuit-architecture) theoretical explorations. We demonstrated experimentally the N3ASIC nanofabric at sub-30nm scale in 2014 and working on 3D Skybridge. I teach entrepreneurship and technical topics. My group is a winner of 9 Best Paper/Poster awards since 2008.
My other interest is in architecting for security and is related to my entrepreurial activities. I founded BlueRISC Inc in 2002, a technology company that develops softcore secure processors and system assurance tools, e.g., for the purpose of software vulnerability analysis. WindowsSCOPE, another of my initiatives, targets cyber-security forensics tools for incident responders (to find evidence of an intrusion/compromise). These systems and tools are sold in 16 countries worldwide.
I am the Director of the Nanoscale Architectures Laboratory. I co-led the Nanoelectronics Technical Research Group at the CHM/NSEC NSF-sponsored nanoscience center and was a member of its executive committee. I was also a member of the FENA/FCRP-DARPA nanoarchitectonics research center executive committee and a Theme Lead for the Nanofabrics research theme between 2008-2012.
I am the General Chair of of Nanoarch IEEE/ACM International Symposium on Nanoscale Architectures in 2017 in Newport, RI. I was General Chair or Co-Chair in 2011, 2012, 2013, 2014, 2015, 2016 (San Diego, Amsterdam, NYC, Paris, Boston, and Bejing).
I was the first steering commitee chair of IEEE Transactions on Multi-Scale Systems (helped with its launch and editorial board, 2014-2015), was an Associate Editor (AE) for IEEE Transactions on Nanotechnology (2009-2015). I served as an AE of IEEE Transactions on Computers (2001-2006). I was the Guest Editor (GE) of the Elsevier JPDC Special Issue: Computing with Future Nanotechnology. I am currently the GE of a Special Issue on 3D ICs (2016, Revolutionary 3-D Integration and Design for Next Generation Computing), and Computing with Nanotechnology (in IEEE Transactions on Nanotechnology). I am also a member of the ACM/SIGDA technical committee on emerging technologies.
OPEN POSITIONS: PhD, MS, and postdoc.
