Dan Ginsburg

Aaftab Munshi is the spec editor for the OpenGL ES 1.1, OpenGL ES 2.0, and OpenCL specifications and coauthor of the book OpenGL ES 2.0 Programming Guide (with Dan Ginsburg and Dave Shreiner, published by Addison-Wesley, 2008). He currently works at Apple.

Benedict R. Gaster is a software architect working on programming models for next-generation heterogeneous processors, in particular looking at high-level abstractions for parallel programming on the emerging class of processors that contain both CPUs and accelerators such as GPUs. Benedict has contributed extensively to the OpenCL’s design and has represented AMD at the Khronos Group open standard consortium. Benedict has a Ph.D. in computer science for his work on type systems for extensible records and variants. He has been working at AMD since 2008.

Timothy G. Mattson is an old-fashioned parallel programmer, having started in the mid-eighties with the Caltech Cosmic Cube and continuing to the present. Along the way, he has worked with most classes of parallel computers (vector supercomputers, SMP, VLIW, NUMA, MPP, clusters, and many-core processors). Tim has published extensively, including the books Patterns for Parallel Programming (with Beverly Sanders and Berna Massingill, published by Addison-Wesley, 2004) and An Introduction to Concurrency in Programming Languages (with Matthew J. Sottile and Craig E. Rasmussen, published by CRC Press, 2009). Tim has a Ph.D. in chemistry for his work on molecular scattering theory. He has been working at Intel since 1993.

James Fung has been developing computer vision on the GPU as it progressed from graphics to general-purpose computation. James has a Ph.D. in electrical and computer engineering from the University of Toronto and numerous IEEE and ACM publications in the areas of parallel GPU Computer Vision and Mediated Reality. He is currently a Developer Technology Engineer at NVIDIA, where he examines computer vision and image processing on graphics hardware.

Dan Ginsburg currently works at Children’s Hospital Boston as a Principal Software Architect in the Fetal-Neonatal Neuroimaging and Development Science Center, where he uses OpenCL for accelerating neuroimaging algorithms. Previously, he worked for Still River Systems developing GPU-accelerated image registration software for the Monarch 250 proton beam radiotherapy system. Dan was also Senior Member of Technical Staff at AMD, where he worked for over eight years in a variety of roles, including developing OpenGL drivers, creating desktop and hand-held 3D demos, and leading the development of handheld GPU developer tools. Dan holds a B.S. in computer science from Worcester Polytechnic Institute and an M.B.A. from Bentley University.

John Kessenich

John M. Kessenich, staff software engineer at Google and creator of SPIR-V, has been active in OpenGL and GLSL Khronos standards’ development since 1999. He is the primary editor of the SPIR-V and GLSL specifications, and creates shader compiler tools and translators to promote portability of those standards.

Graham Sellers, AMD Software Architect and Engineering Fellow, is a Khronos API lead and represents AMD at the OpenGL ARB. He has contributed to the core Vulkan and OpenGL specs and extensions, and holds several graphics and image processing patents.

Dave Shreiner is a twenty-five year veteran of the computer graphics industry, where he’s worked almost exclusively with programming interfaces like OpenGL. In addition to having written and taught instructional courses on using computer graphics APIs, he was also the lead author for almost ten years on several Addison-Wesley publications relating to computer graphics.

Bill Licea-Kane

Randi J. Rost was a core contributor to the development of the OpenGL Shading Language and the OpenGL API that supports it, as well as one of the first programmers to design and implement shaders using this technology. Randi works at Intel.
