Thomas J. Watson Research Center, Yorktown Heights, NY USA
I'm a Research Staff Member at the IBM T.J. Watson Research Center in Yorktown Heights, New York.
I have received the MS degree in Physics from Moscow Institute of Physics and Technology in 1989, and the PhD degree in Physics from SUNY Stony Brook in 1997.
At Stony Brook I worked on the design and testing of superconductor integrated circuits based on Josephson junctions. I started at IBM on March 17, 1999, working on the design and testing of high-speed digital and mixed-signal communication circuits for optical and channel-limited wireline communications.
I was part of the team that pioneered the DPLL research at IBM in 2005. The DPLLs are now used in a number of IBM products, including P7 microprocessor and many others.
The 30 Gb/s VCSEL-based optical link was highlighted in Electronics Letters interview (2011) and the 40 Gb/s link was presented at OFC 2012.
I also work on circuits for Silicon Photonics.
In 2012 I was a speaker at the ISSCC 10-40 Gb/s I/O Design Forum (“Optical vs. Electrical I/O: Reach, Bandwidth, Power Efficiency, Density and Cost”)
In 2011, 2012 and 2013 I was a short course instructor at OFC ("Computercom Interconnects: Circuits and Equalization Methods for Short Reach Power-Efficient Optical and Electrical Links")
