call me "Dr. Greenspun" because my brother is a real doctor).
2018-present: Harvard University
Develop curricular materials for medical students and post-doc
researchers learning how to query a 12 TB insurance claims
database. Assist student groups with their analytics projects in SQL
2013-present: Fifth Chance Media LLC
I develop software, write, photograph, and create videos for this
publishing company whose current products are listed
at fifthchance.com. Through
Fifth Chance Media LLC I also work as
a software expert witness, especially
software patents. I have also served as
an aviation expert
witness, testifying in front of a Federal Court jury, and as a
relational database expert
1997-present: various advisory and corporate boards
Serve as an independent member of various advisory and corporate boards,
mostly for technology companies. Example: Joined corporate board of MIT
materials science spin-off in late 2005 during $550,000 seed capital
phase. Stepped down when company secured $10 million in venture capital
1991-present: Computer Science and Artificial
Intelligence Laboratory, Massachusetts Institute of Technology.
Teach and expand the MIT computer science curriculum, conduct
research, and supervise student research.
1993-2000; 2006-2007: photo.net
Started, programmed, financed, and managed this online learning
community as a personal hobby. Spun it off in 2000 to a team of
entrepreneurs who attempted to make it a profitable business. Took it
back over in mid-2006 to clean up the content, software, and balance
sheet (crippled with debt). With 600,000 registered users and 60
million page views per month, sold the company in April 2007 to
1997 through March 2000: ArsDigita Corporation
Started, financed, and managed this company, which developed an
open-source toolkit for building collaborative Internet applications.
Grew the company profitably from 5 part-time people to 80 full-timers
and revenue of $20 million per year. Between January and March 2000,
negotiated and closed a $38 million venture capital investment from
Greylock and General Atlantic Partners. Handed over the reins to a team
of professional managers brought in by the venture capitalists.
February 1988 through August 1990: Isosonics Corporation
Founded company to develop a product that stored digital data with
consumer video recorders. Co-designed custom digital signal
processor. Developed simulation environment, complete simulator for
digital audio recorder (1.4 Mbits/second), microcode compiler on the
Symbolics Lisp Machine. Used Lisp tools to develop error correction
microcode and refine DSP architecture. Co-designed three phase locked
loops. With partners, developed system for auditing television
broadcasts nationwide by monitoring commercials and compiling reports
for advertisers. We designed a single board that tunes a chosen
channel, recognizes tagged advertisements and makes a record for each
ad of time of broadcast, number of fields, video quality and color
burst presence. Served as president of Isosonics from its inception
until its dissolution.
April 1986 through November 1989: ConSolve Incorporated
Co-founded this construction automation company. With partner,
developed initial product, obtained financing (from PaineWebber
Ventures), hired software development, marketing and support
staff, established R&D partnership with Tektronix, obtained
government contracts and sold software. Was active participant
in all important planning, legal, and management activities.
Wrote every line of code in the first system shipped to a
November 1984 through August 1985: ICAD, Inc.
Co-founded company with three partners. With Patrick O'Keefe,
developed Lisp software to automate mechanical engineering.
System was initially primarily intended for large steel structures,
e.g., air-cooled heat exchangers, offshore oil rigs, coal-fired power
plants, but has been extended to many general ME problems.
Company went public in January 1995 as Concentra with a market
valuation of $50 million and was subsequently acquired by Oracle
June 1983 through November 1984: Symbolics, Inc.
Developed VLSI tools, including automatic layout functions and worked
on the system architecture for the Ivory microprocessor (the base of
all Symbolics products sold in the late 1980s). Wrote parts of the
Symbolics operating system.
June 1982 through June 1983: Hewlett-Packard Labs
Wrote packet-switched network simulation software on Symbolics Lisp
Machine. Helped architect, simulate and design prototype of HP's
Precision Architecture RISC computer. The prototype took two
man-years to complete and ran at VAX 11/780 speed in June 1983. This
architecture became the basis of HP's computer product line for 15
years and then became the basis for the 64-bit generation of Intel
1978 to 1982
Paid tuition and living expenses through MIT
with employment and contract work for Wang Laboratories, Verbex
Corporation, National Aeronautics and Space Administration, and
Education (Massachusetts Institute of Technology)

engineering and construction.
S.B. 1982 in mathematics. Completed coursework for electrical
engineering S.B. with emphasis on digital systems and signal
processing. Took undergraduate and graduate computer science
courses, with an emphasis on algorithms. Took graduate courses
in microeconomics and neurophysiology.
