Assistant Instructor, Teaching Assistant, and Graduate Research Assistant; The University of Texas at Austin, Department of Computer Science, Austin, Texas; 2009–present

Programming languages research with Profs. Chris Rossbach, William Cook, and Jayadev Misra, investigating “computational orchestration” — specifically the model of programming languages and distributed computing embodied by Orc.

Created and maintained the Orc Eclipse integrated development environment plug-in.

Created proof-of-concept implementation of security typing (secure information flow) in Orc.

Formalized an Orc “token semantics” — a form of structural operational semantics.

Currently investigating distributed orchestration, and robotics applications of orchestration languages.

[See also university-level teaching section below.]

Engineering Graduate Student; Caltech/NASA JPL (Jet Propulsion Laboratory), Pasadena, California; 2015

Designed and led development of numerous large software systems.

Directed I.T. projects and programmes as part of contracts valued from $64k to $700M.

Led technology adoption and education for company teams, and acted as “consultant to the consultants” for software engineering practices such as: object oriented development, iterative development, Web systems development, distributed systems, and human-computer interaction.

Technology and management expert for critical project situations: advanced technology introduction, “turnaround” (get out of trouble), and “schedule crash” (faster than reasonable).

Developed project proposals for government and business clients.

Initiated and directed the EDS+University Collaboration Programme.

Diverse set of clients, including: American Airlines, Bank of America, Bell Helicopter, Commonwealth Bank of Australia, eBay, Everest Funeral, GM, National Heritage Insurance Company, Norwegian Cruise Line, Safety-Kleen, U.K. Inland Revenue, U.S. Dept. of Veterans Affairs, U.S. Military Healthcare System, U.S. Postal Service, and United Airlines.

Technical Consultant; COMSYS Technical Services, Inc., Rockville, Maryland; 1992–1994

Reengineered and enhanced digital telecommunications test equipment remote control software. Maintained system’s proprietary windowing system and multitasking executive. Wrote utilities, including field programmable gate array (FPGA) program download.

Provided technical leadership to make prototype U.S. military ID card system feasible within the constraints of its three-tier distributed platform architecture.

Engineering Consultant; Obert Associates, Inc., University Park, Maryland; 1990–1992

Developed fluid dynamics modeling software for:

Prepared engineering project reports for manufacturing, aerospace, and military applications.

Research Assistant; University Research Foundation/Maryland Advanced Development Laboratory, at the U.S. Naval Academy, Annapolis, Maryland; 1989

Developed data acquisition and control software and hardware for vortex ring research project.

Assisted with experimental runs (apparatus construction, data collection, etc.).
