Talk Title: New Approaches to Modeling and Control of Compl

ex Dynamics

Talk Abstract:
Complex phenomena such as animal morph

ology human motion and large
fluid systems challenge even our most sop

histicated simulation and
control techniques. My overarching research go

al has been to develop
fundamentally new methods to approach such high-d

imensional and
nonlinear problems. This talk presents my work solving th

ese problems
across a wide range of phenomena including a new model-red

uction
approach to fluids that is orders-of-magnitude faster than standa

rd
simulation methods and enables interactive high-resolution fluid
s

imulation for the first time. Another example is a continuum
approach to
crowd dynamics which efficiently reproduces empirical
aspects of large

crowd behavior that would be difficult or impossible
to achieve with tra

ditional agent models. The talk will also cover
work on several other ph

enomena including human animation
animal morphology and protein foldi

ng. Such new algorithmic
approaches advance not only our ability to sim

ulate and control
complex systems but also our understanding of the sys
