Oguz (Mehmet Oguz Derin, 𐱅𐰼𐰭𐰆𐰍𐰔) is a software data engineer working on processing and visualizing volumetric data at Morgenrot, Inc., and a W3C Invited Expert for GPU for the Web Working Group. His previous experience includes: translating a RISC-V course and textbook for Imagination Technologies, contributing a linguistic dataset for Universal Dependencies, building extensions in Unreal Engine Marketplace, freelancing for Virtual Reality startups, and developing indie mini-games for iOS and Android using Unity Engine and Unreal Engine.

Takahiro Harada is a researcher and the architect of a GPU global illumination renderer called Radeon ProRender at AMD. At the same time, he’s leading software development in Morgenrot, Inc. He developed Forward+ and GPU rigid body simulation solver, which is used as a base of the Bullet physics engine OpenCL implementation. Before joining AMD, he engaged in research and development on real-time physics simulation on PC and game consoles at Havok. Before coming to the industry, he was in academia as an assistant professor at the University of Tokyo, where he earned his Ph.D. in Engineering.

Yusuke Takeda is a postdoctoral fellow at the Department of Earth and Planetary Science, Hokkaido University. He also works as a researcher at The Hokkaido University Museum and The University Museum, The University of Tokyo. His current research interests are processing and visualization of large-size image sequence data acquired from various tomographic devices. He has also developed a multi-dimensional petrographic imaging system. His academic career started as a paleontologist focusing on ammonite fossils. He received his Ph.D. degree at the University of Tokyo in 2017.

Yasuhiro Iba is an associate professor at the Department of Earth and Planetary Sciences, Hokkaido University. His current research interest is the development of high-resolution tomography systems for paleobiology and astrobiology. He received his Ph.D. degree at the University of Tokyo in 2008.
