Employment Experience

1991-present: Massachusetts Institute of Technology

Teach and expand the MIT computer science curriculum, conduct research, and supervise student research. Teach the most popular course in the MIT Department of Aeronautics and Astronautics, 16.687 (via Zoom for 2021 and 2022, with approximately 1000 students total)

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 and R.

Fall 2021: Florida Atlantic University

Teach Information Security at this 31,000-student branch of the State University System of Florida.

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 in cases regarding Internet software patents (e.g., for Amazon, Ford, IBM, Microsoft, and the U.S. Department of Justice). I have also served as an aviation expert witness, testifying in front of a Federal Court jury, and as a relational database expert witness. Most recent trial: Express Mobile v. GoDaddy (verdict for the defense in March 2023).

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 NameMedia.

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 customer (Caterpillar).

November 1984 through August 1985: ICAD, Inc.

Co-founded company with three partners. With Patrick O'Keefe, developed Lisp software to automate mechanical engineering. The ICAD 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 Corporation.

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 processors.

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 other organizations.

Education (Massachusetts Institute of Technology)

Ph.D. 1999 in electrical engineering and computer science. Thesis title: Architecture and Implementation of Online Communities.

S.M. 1993 in electrical engineering and computer science. Thesis title: Site Controller: A system for computer-aided civil 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.
