Charles A. Czeisler - Sleep, circadian rhythms, health and performance
With more than 40 years’ experience in the field of basic and applied research on the physiology of the human circadian timing system and its relationship to the sleep-wake cycle, Dr. Czeisler is interested in the physiology of the hypothalamic circadian pacemaker in humans, photic and non-photic synchronizers of the human circadian pacemaker, temporal dynamics in neuroendocrine systems, homeostatic and circadian factors in the regulation of sleep and alertness, and the application of circadian physiology to occupational medicine/health policy, particularly as it relates to the extended duration work shifts and long work weeks.

John Owens- Hard and Fun Problems on GPUs: Irregularity and Parallelism for Next-Generation Computing
The computational power of GPUs, coupled with increasing programmability, is making the GPU a compelling platform for high-performance computing. GPUs excel at regular, structured computation, but irregular computation -- where processors consume an irregular, runtime-dependent amount of input or produce an irregular, runtime-dependent amount of output -- is a challenging problem in a parallel computing environment. These characteristics are common in today's real-time graphics pipelines but are typically handled in hardware. We anticipate these problems will become more relevant as we move toward the next generation of graphics systems that have at their core *programmable real-time graphics pipelines* and must instead support these workloads in more general-purpose ways.
