Dr. Kerpez received his B.S. in Electrical Engineering from Clarkson University in 1983 and his M. S. and Ph. D. in Electrical Engineering systems from Cornell University in 1986 and 1989. Since then he has been at Telcordia Technologies, where he has performed detailed computer simulation studies, technical analyses, and consulting on digital communications systems operating over a variety of media. He has analyzed, optimized, invented, and helped standardize new transmission systems, modulation techniques, codes, equalizers, multiplexing and networking techniques for digital local access telecommunications systems. Kerpez worked extensively on high-rate digital subscriber lines (HDSL), and he was instrumental in the invention and subsequent definition of asymmetric digital subscriber lines (ADSL). He has been active in the T1E1.4 xDSL standards committee since 1989. Kerpez has also performed advanced system studies on very high rate digital subscriber lines (VDSL), 1-Meg modems, single-pair HDSL, and splitterless ADSL. He has performed many spectral compatibility studies of xDSL systems, and has recently defined guidelines for xDSL compatibility which are becoming ANSI standards for an unbundled loop environment. Kerpez has also worked extensively on PCS radio access systems, and on hybrid fiber/coax transmission systems and networking algorithms.

Much of Kerpez's recent work is on residential inside wiring, home automation, and in-home residential LANs. He has written requirements for internetworking TCP/IP, ATM, and IEEE 1394 (Firewire) with residential gateways carrying data and MPEG or DV video in the home. He has been active in the TIA/EIA Residential Gateway standards and the VESA Home Network standards. Kerpez has extensively analyzed and developed new algorithms for broadband digital transmission on in-home twisted-pair and coaxial cabling, including studies of 10/100Base-T and IEEE 1394 (Firewire) transmission over residential inside-wiring. Kerpez has studied wireless home networks and high-speed digital transmission on residential electric power lines. He has developed residential gateway experimental laboratory prototyes and has performed laboratory testing of in-home digital transmission systems.

Kerpez has authored over 100 technical papers. He is experienced in computer programming: Visual C++ applications, mathematical C/C++, Fortran, and business software programming.
