Eftychios Sifakis is a post-doctoral researcher at the University of California Los Angeles (with a joint appointment in Mathematics and Computer Science). He completed B.Sc. degrees in Computer Science (2000) and Mathematics (2002) from the University of Crete, Greece, and a Ph.D. degree in Computer Science (2007) from Stanford University, under the supervision of Ron Fedkiw. His research focuses on scientific computing, physics based modeling and computer graphics. He is particularly interested in biomechanical modeling for applications such as character animation, medical simulations and virtual surgical environments. Eftychios is a research consultant with Walt Disney Animation Studios, and has previously held consulting positions at Intel Corporation and SimQuest LLC.

Digital doubles have not only evolved into prevalent elements of motion pictures and games, but are also finding an ever growing application base including medical diagnostics, surgical planning and design of vehicles and crafts. At the same time, current and emerging applications demand improved photorealism, enhanced biomechanical accuracy, better subject-specificity and faster simulation algorithms. As these demands often outgrow the evolution of computer hardware, new algorithms for biomechanical modeling and simulation are necessary to ensure that we make the optimal use of emerging computational platforms. In this talk I will discuss a number of techniques that were designed to facilitate modeling and simulation of digital characters with high accuracy and efficiency. Technical aspects of these methods include mesh generation, robust simulation, accurate anatomical modeling and parallelism. Finally, I will discuss the impact of these algorithmic techniques in broader theoretical and engineering problems, and how they may be leveraged in other application areas such as fracture mechanics, fluid-dynamics, solid-fluid coupling, and parameter estimation problems.
