Xiling ShenStanford UniversityAbstract:Caulobacter is a model system for studying bacterial cell cycle. A regulatory circuitry made of cascading regulatory proteins senses and regulates various cell functions, forming nested feedback control loops. By integrating the continuous regulator models with the discrete cell function models, a scalable hybrid control model was constructed that accurately simulates cell cycle regulation under various conditions for different mutant phenotypes. A novel adaptation of a formal verification tool from asynchronous circuit design further identified potential timing hazards in the regulatory circuitry. Ensuing experiments in-vivo revealed novel robustness mechanisms that were not expressed under normal lab conditions.Biography:
Xiling Shen is a PhD student in the Electrical Engineering Department at Stanford University. His current research interest focuses on modeling and analyzing biological regulatory networks using engineering concepts and tools.Xiling Shen received his BS and MS degree from the Electrical Engineering Department of Stanford University in 2001. He worked at Barcelona Design Inc., a semiconductor startup for two years, specializing in analog circuit design and optimization, before joining Professor Mark Horowtiz' research group in the Electrical Engineering Department at Stanford in 2003. In the first two years of his PhD, Xiling Shen collaborated with Professor Joseph Kahn to use adaptive spatial equalization to compensate modal dispersion in multimode fibers. Starting from 2005, Xiling Shen has been collaborating with Professor Harley McAdams, Professor Lucy Shapiro, and Professor David Dill to model and analyze the robustness of the Caulobacter cell cycle regulation.

Title: Interactive and Intuitive Appearance DesignSpeaker: Prof. Fabio Pellacini (Dartmouth)ABSTRACT:
The appearance of objects comes from the interaction of scene lighting
and surface materials, whose careful definition is necessary to achieve
the remarkable sophistication of today's synthetic imagery.
Currently, appearance design is one of the remaining roadblocks for a
ubiquitous use of computer-generated imagery, since slow user feedback
and cumbersome user interfaces make the process significantly time
consuming for expert designers, and beyond the reach of novices.In this talk, I will present our recent results in rendering accurate
lighting for complex environments where we achieve interactivity by
developing new approximation algorithms that can take advantage of
inherent properties of lighting and of today's commodity hardware
architectures. These algorithms completely change the workflow of
artists from an offline to a fully interactive process.
I will also show results from algorithms that build on this
interactivity to support intuitive user interfaces for appearance
design that drastically simplify the time required for designing
appearance.BIO:
Fabio Pellacini is an assistant professor in computer science
at Dartmouth College. His research focuses on algorithms for interactive,
high-quality rendering of complex environments and for artist-friendly
material and lighting design to support more effective content creation.
Prior to joining academia, Pellacini worked at Pixar Animation Studios
on lighting algorithms, where he received credits on various movie
productions.
Pellacini received his Laurea degree in physics from the University of Parma
(Italy), and his M.S. and Ph.D. in computer science from Cornell University.
Pellacini received an NSF CAREER award and a Dartmouth Junior Faculty
Fellowship for his research contributions.Location: Seaver Science Library (SSL) - 150
