Accomplished software developer, system architect, technical lead, and project manager in the areas of video, image processing, scientific instrumentation, and visualization. 

Over 20 years software and 9 years computer hardware design experience.

Areas of Expertise

Extensive experience in developing applications, system services, and drivers for Microsoft Windows, Windows Phone, Silverlight, WPF, and Windows Mobile.

Working first in hardware design and later in software, I have had primary responsibility for a number of innovative, commercially successful products.  A general thread throughout my career has been the integration of video and computer graphics. 

While working at Microsoft I was the primary author of the video capture interface for Microsoft Windows which has arguably spawned the largest corpus of digital content anywhere on the web: streamed and captured video.


Microsoft Windows, Windows Phone, C#, C/C++, Python, javascript, XAML, Silverlight, Blend, AWS, Azure, MVVM, WPF, ASP.NET, WDM, VFW, DirectShow, video, capture, image processing, image analysis, machine learning, MPEG.

Pocket Stars

Star chart, star finder, ephemeris, and celestial navigation calculator for the Windows Mobile Pocket PC, Smartphone and Windows desktop. Winner of multiple awards in the Best Education Application and Best Astronomy Application categories.  Over 300,000 downloads.  See:


Microsoft Windows Video Capture

Primary architect at Microsoft for the WDM video capture model, which is integral to all versions of Microsoft Windows since Win98.  This core system infrastructure is to capture, stream, and route video, tune broadcast signals, and control conferencing cameras.  The technology is used by capture applications such as Premiere, Netmeeting, Skype, Windows Messenger, Flash, Media Center, and virtually every other product which captures live video and integrates television functionality into Windows.



One of two primary authors of a Windows based image processing, analysis, measurement, and visualization toolbox and application generator for biomedical and industrial applications ($4K / seat).  Sold to Media Cybernetics.



One of the earliest video image capture and enhancement programs for desktop publishing under Windows. Licensed to Aldus Corporation (ultimately Adobe).


Color Sonar

Hardware and software design of world's first commercial scanning sonar utilizing color video display technology.

Microsoft Corporation     Redmond , WA

1992 - 2000


Primary architect of the video capture and television infrastructure in the Microsoft Windows Operating Systems. This work has spanned two generations of development: VFW introduced in 1992, and WDM introduced in 1998. In both cases this involved design and implementation of the driver and streaming model, as well as the user mode infrastructure used by applications to acquire video for editing, conferencing, television tuning,  and image processing.

The WDM model is the successor to VFW and is available on Win98 through Win8.  This technology is used by Media Center and virtually all Windows video capture and telepresence applications.  WDM video capture includes worldwide tuning for both analog and digital broadcast television, support for 1394 and USB cameras, PCI and videoport capture hardware, and is fully integrated with the DirectShow environment.

In addition to writing a number of sample and production drivers for both VFW and WDM, I am primary author of Vidcap, AVICap, and a number of DirectShow filters for television tuning, video routing, MPEG transport stream analysis, and VBI and audio software oscilloscopes. While focusing on product design and implementation, I have also acted as a technical lead for other developers, given numerous technical seminars at venues such as Meltdown and WinHec, and provided significant outreach and support to the hundreds of IHVs and ISVs developing drivers and applications for both capture models. My design, development and debugging skills span user and kernel mode. I am particularly strong in the areas of C/C++ programming, WDM drivers using the Stream Class, Kernel Streaming, and DirectShow, video, television, and MPEG.
