Modern science and engineering applications give rise to vast quantities
of high-dimensional data.  This talk will provide a broad research
perspective on the challenges and opportunities (both mathematical and
practical) presented by such data sets.  For the large collections of
sounds, images, and network data acquired by modern sensing devices,
traditional signal processing techniques singularly fail to scale, and
new approaches are needed. Three concrete research examples will be
considered in this talk:  large-scale speech analysis, high-resolution
imaging, and the modeling of high-dimensional graphs and networks.  For
each of these contemporary application domains, it will be shown how a
careful blend of new models, inference frameworks, and algorithms can
lead to efficient and practical engineering solutions with provable
performance guarantees.


Patrick J. Wolfe is an Associate Professor at the Harvard School of
Engineering and Applied Sciences, Department of Statistics, and
Harvard-MIT Division of Health Sciences and Technology.  He founded the
Statistics and Information Sciences Laboratory at Harvard in 2004 to
focus on statistical signal processing and its application to tasks
involving modern high-dimensional data sets, in particular sounds,
images, and networks.  His work in these areas led to a 2008
Presidential Early Career Award for Scientists and Engineers, and he has
also received honors from the IEEE, the Acoustical Society of America,
and the International Society for Bayesian Analysis. Government and
industry sponsors include ARO, DARPA, NGA, NIH, NSF, MIT Lincoln
Laboratory, Draper Laboratory, Texas Instruments, and Sony Electronics,
