Title: Dynamic digital faces and bodies: Challenges, applications and
broader impact of biomechanical modeling and simulation technology.
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 developing
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 upcoming computational platforms are utilized to the best
of their capacity. Additionally, biomechanical simulation has provided
a great opportunity for transformative advances in medical practice
using virtual models of the human body for disease prevention and
treatment. These emerging applications mandate an increased level of
attention to the unique demands of subject-specificity and anatomical
accuracy for clinical uses of biomechanical modeling and simulation.
This talk will outline a number of techniques that were designed to
facilitate modeling and simulation of digital doubles with high
fidelity and efficiency. Finally, I will discuss the cross-cutting
impact of such advances on character animation, scientific computing
and virtual surgery.
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. 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.
