Contract Employment History
Cernium Corporation - July 2006 to present
Developed video analytics software in C and C++ running on PCs running Windows and Linux
as well as a family of embedded systems based on the TI DaVinci chip. This software is
used as the basis for a number of different commercial products.
Developed a standalone video analytics appliance using Python and wxPython for the GUI.
Developed the "backend" server processes for a web-based portal that provides customer
access and control of Internet-connected video analytics appliances. This was written in
Python, used the Twisted library for networking and was deployed using Amazon Web Services
(AWS) Elastic Compute Cloud (EC2), Simple Storage Service (S3) and Elastic Block Storage
(EBS) products.
Developed Puppet and Python-based system administration automation to deploy and manage
multiple such web-based portals, including monitoring, email, logging, package management
and high-availability.
Developed miscellaneous research tools, product prototypes and pilots in C, C++, C# and
Python.
Sarnoff Corporation - August 2003 to December 2005
Developed a commercial product (TerraSight 3D Visualizer) for Windows XP based on the
battlespace visualization system described below for aerial video exploitation and
visualization. This included a separate application written in C# using the ESRI
ArcObjects library for processing raw satellite imagery and digital elevation data into a
form suitable for real time 3D rendering.
Helped develop a 3D situational awareness display for a commercial Windows application
(Hawk) used for video surveillance site security using C++, C# and ActiveX.
Developed a Windows application in C++ using MFC for performing superresolution on video
sequences.
Developed a Windows client application in Python using wxPython and a Linux server
application in Python for genomic research (finding unique microarray probes.)
Sarnoff Corporation - September 1999 to September 2002
Developed a multithreaded, CORBA-based system on Linux PCs in C++ and Python using OpenGL
for real time rendering of battlespace visualizations of massive amounts of geospatial
(topography and satellite imagery) and military unit data as well as multiple video feeds
from UAVs projectively textured on terrain.
Developed a parallel, distributed volume rendering application in C++ that ran on a
cluster of Linux-based computers. Also wrote a high performance network-based viewer for
this and other applications.
Developed a distributed suite of Windows NT server and client applications in C++ using
MFC and DCOM that captured video sequences from a large array of cameras in real time to a
cluster of computers for the purpose of providing a continuously variable playback view of
the scene from any perspective.
Developed a Windows NT application in C++ using MFC that controlled an instrument for
characterizing the shape and velocity of droplets emitted from inkjet printer heads. The
software handled calibration, driving the printer head, capturing high-speed data and
analyzing and presenting the results.
Sarnoff Corporation - April 1994 to December 1998
Developed a distributed, scaleable, CORBA-based system in C++ using the X Window System,
Motif, Tcl/Tk, Scheme, OpenGL, OpenInventor, Optimizer, ImageVision and Performer on SGI
computers (from Octanes to 3 pipe Onyx2 InfiniteReality) for 3D stereoscopic display of
theater-level battlespace visualizations across multiple, large, mosaiced projection
displays.
Developed a distributed, RPC-based testbed system in C++ using the X Window System,
Motif, GL, OpenGL and ImageVision on SGI workstations for applying virtual reality
techniques to the task of searching very large (ten gigapixel) satellite images using a
variety of input and output devices including head mounted displays.
CHI Systems - February 1994
Assisted in the design of a distributed, RPC-based software architecture for X Window
System and Motif graphical user interfaces for a large telecommunications company.
An Aerospace Company - January 1994
Provided on-site training to software engineers in the X Window System, GL, OpenGL and
real-time Unix programming techniques.
Martin Marietta Management & Data Systems - June 1993 to January 1994
Performed analysis and design of an architecture for a distributed human-computer
interface for control of Motorola's IRIDIUM satellite telephone network using the X Window
System and Motif on Sun workstations.
General Electric Management & Data Systems - July 1992 to July 1993
Developed human-computer interface software using the X Window System and Motif on Sun
and Intel-based workstations to perform SQL database query and updating, electronic mail
and file transfer.
General Electric Advanced Technology Lab - March 1990 to March 1992
Developed human-computer interface software for a DARPA research program applying
distributed AI technology to the command and decision process on submarines. The system
ran on a network of Sun and SGI workstations.
Developed 2D and 3D visualizations of underwater acoustic propagation data using various
toolkits (apE, Khoros, NCSA) and custom software using both SGI's GL and the X Window
System.
Franklin Institute Futures Center - April 1989 to August 1990
Developed software for an interactive networking exhibit using IBM PS/2's running AIX
using TCP/IP and the X Window System.
Environmental Tectonics Corporation - October 1986 to October 1989
Developed the following real-time, three dimensional graphics software in C using Unix on
SGI workstations:
Flight simulation and target tracking software generating out-of-the-window scenes for
jet fighter pilot training.
Simulated cockpit instrumentation using computer-generated imagery.
Software to specify motion for and perform real-time kinematic analysis and simulation
of robot-like machinery.
Developed "walk through" package for interactive visualization of buildings and
factories.
Wrote AutoCAD translator software and AutoLISP 3D geometry creation and verification
tools.
Visualization of finite element analysis and strain gage results.
Employment History
Martin Marietta Orlando Aerospace - July 1982 to August 1984
As an engineer in the Computer Aided Engineering Department, evaluated and used
commercial programs for mechanical design and analysis (e.g. solid modelers and finite
element solvers such as SDRC IDEAS and MSC NASTRAN) and trained others to use these
programs. Wrote software to interface these programs with each other. Also wrote a finite
element solver for the analysis of incompressible solids.
