I am a Software Engineering Manager at Apple Inc. Before that, I was
Co-Founder and CTO of PullString Inc. and was Founder and CEO of Code
Reddy Inc. I have also led software engineering teams at Pixar, Linden
Lab, and SRI International. I hold a Ph.D. in Computer Science, am the
author of over 40 published articles, 9 issued patents, and I have
written 2 computer science text books.
I lead a team of talented software engineers
working on delivering new capabilities for Apple products.
I was Co-Founder and CTO of
PullString, Inc. for 8 years. PullString was a Softare-as-a-Service (SaaS) company
providing a platform to create conversation experiences and apps on
various voice platforms such as Amazon Alexa and Google Assistant.
We provided conversational AI and dialog management solutions as
well as a powerful authoring environment to design, test, and deploy
I was the Founder and CEO of
the technology consultancy Code Reddy Inc. Through this position I
provided software design and development services for various
technology clients, including Linden Lab, Weidlinger
Associates, and Planet 9 Studios. My work for Linden Lab involved
improvements to the Second Life client, an online 3D virtual world
used by over 20 million people worldwide.
Bakery Animation Studio
I was an Engineering
Manager at The Bakery, a startup animation studio in the south of
France. In this role I had responsibility for architecting and
designing the studio's 3D animation software, as well as managing the
team of engineers tasked with implementing the software.
Pixar Animation Studios
I was a Lead
Engineer in Pixar's R&D department for 6 years. In this role I
was responsible for managing a team of engineers designing and
implementing Pixar's in-house film-making software system,
Marionette. My work was used on the films: Finding Nemo, Cars,
The Incredibles, Ratatouille, and WALL-E. My head
was also used as a model for Mr. Incredible.
I worked at SRI
International for 5 years as a Research Engineer. My primary project
was a distributed 3D terrain visualization system called
TerraVision. This effort also involved international standards-based
work as chair of the GeoVRML working group (I was the author of all
the geospatial nodes in the VRML and X3D ISO standards), and work on
a scheme to index all geospatial information on the Internet, referred
to as the GeoWeb.
I wrote a
book called API Design for C++, published by Elsevier/Morgan
Kaufmann in 2011. This book focuses on how to design robust and
elegant Application Programming Interfaces (APIs) with a focus on the
C++ language. The accompanying web site provides source code examples
and a blog with articles on good API design.
co-authored the book Level of Detail for 3D Graphics, published
by Morgan Kaufmann in 2001. The book covers the topic of creating and
managing multiresolution models for real-time 3D graphics
applications. The accompanying web site provides links to related LOD
resources on the Web.
I gained my Ph.D. from the University of Edinburgh in 1997. My
research involved applying models of visual perception to real-time 3D
graphics systems. The goal of this work was to remove imperceptible
details in order to improve the frame rate of graphics systems.
I have published a large
number of peer-reviewed journal articles and conference papers,
including articles in IEEE Computer Graphics and Applications
and courses at the annual SIGGRAPH conference. I have also
given various invited talks, such as the Keynote Address at the
Web3D conference. My first publication was in Your
Commodore magazine when I was 16 years old.
My feature film credits
include Finding Nemo, Cars, The Incredibles,
Ratatouille, and WALL-E. In addition, I've worked on
technology that was used in many of Pixar's short films. You can
view my entire filmography on the IMDB web site.
