Dr. Yurii Vlasov is a Founder Professor of Engineering at the University of Illinois at Urbana-Champaign. He is tenured with the departments of Electrical and Computer Engineering, Materials Science and Engineering, and Bio-Engineering, as well as affiliated with Beckman Institute for Advanced Science and Technology and Micro and Nanotechnology Laboratory. At the UIUC he established two experimental labs: the first one focused on integrated photonics for biomedical applications and the second lab dedicated to experimental systems neuroscience. These two main directions reflect his current interest in applications of engineering solutions to life sciences.

Prior to joining the UIUC, Dr. Vlasov held various research and managerial positions at the IBM T.J. Watson Research Center in N.Y. where he led broad company-wide efforts in integrated silicon nanophotonics and more recently in neuromorphic computing architectures. He initiated the Silicon Nanophotonics project in 2001 and managed it for over 15 years from its early fundamental research stage up to commercial manufacturing of optical transceivers for large-scale datacenters and supercomputers.

Prior to IBM, Dr. Vlasov developed semiconductor nanophotonics at the N.E.C. Research Institute in Princeton, N.J. and at the Strasbourg IPCMS Institute in France. For over a decade, he was also a Research Scientist with the Ioffe Institute of Physics and Technology in St. Petersburg, Russia working on optics of nanostructured semiconductors. He received his M.S. from the University of St. Petersburg (1988) and Ph.D from the Ioffe Institute (1994), both in physics.

Professional Societies

  • Led development of a novel CWDM4 proposal for the IEEE 100G Ethernet 802.3bm committee that once acquired a highest level of support on the floor. Full baseline proposal (draft clause 96) with all specifications had been prepared for final voting. Although no consensus was reached by 802.3bm, several MSA had been established following the specs of the initial IEEE CWDM4 proposal as CWDM4, CLR4 and Open Optics.
