`
`Chris Heegard
`
`9/00 - 9/02 CTO, Home and Wireless Networking, Texas Instruments, Santa
`Rosa, California.
`
`1/98 - 9/00 CEO and Principal Scientist, Alantro Communications, Inc.
`Santa Rosa California. Alantro Communications was a fabless semiconductor
`company specializing in physical-layer communications with a particular exper-
`tise in forward error correction (FEC). The technology is vital in: high-speed
`wireless local area networking (IEEE 802.11/WiFi), cable modems, digital-tv,
`digital subscriber line and satellite & terrestrial wireless.
`
`1/89 - now Founder and chief scientist for Native Intelligence, a digital
`communications software company.
`
`9/81 - 12/99 Faculty, School of Electrical Engineering, Cornell University.
`Taught courses in analog and digital communications, error-correcting coding,
`information theory, detection and estimation theory, introduction to digital sys-
`tems and audio engineering laboratory: an introduction to audio signal pro-
`cessing. Research in the areas of: turbo coding, coded modulation and trellis
`group codes, algebraic coding theory and algorithms, applications of symbolic
`computation to coding theory, magnetic and optical data recording, sequence
`estimation algorithms, analog source coding and data compression, audio and
`video signal processing, and information theory. The senior advisor of 18 grad-
`uated Ph.D. students.
`
`2/88 - 5/88 Visiting Associate, California Institute of Technology, Pasadena,
`California.
`
`9/87 - 5/88 Visiting Scientist, IBM Almaden Research Center, San Jose,
`California.
`
`9/78 - 6/81 Research Assistant under the supervision of Professors Thomas
`Cover and Abbas El Gamal. Research in a variety of topics in coding, in-
`formation theory and statistics. Ph.D. thesis titled, Capacity and Coding for
`Computer Memory with Defects. This work answers questions concerning the
`capacity of defective computer memory and the description of algebraic error-
`correcting codes for combating defects.
`
`9/76 - 9/78 Research and Development Engineer, Linkabit Corp., 3033 Sci-
`ence Park Rd., San Diego, California 92121. This work involved several develop-
`ment projects related to satellite communications. One major project was the
`computer simulation and hardware implementation of a packet satellite PSK
`modem. The major demodulation algorithms were performed via a bipolar
`microprocessor with a microprogram architecture. This modem connects the
`ARPANET to Europe and formed the basis of a commercial product for Link-
`abit. A second major area of my involvement was the development of several
`sequential decoders for convolutional codes.
