This symposium is a memorial to Dennis E. Slice, professor of scientific computing at Florida State University and honorary professor at the Department of Anthropology, University of Vienna (Austria), senior ambassador and enthusiastic teacher of geometric morphometrics (particularly in anthropology and forensics), and recipient of the fourth Rohlf Medal for Excellence in Morphometrics. Countless anthropological and forensic research projects have exploited his freely available Morpheus software, and without his tireless and selfless moderation of morphmet, the central online forum in morphometrics, the morphometric community would have evolved very differently. Our symposium will honor a specific thrust of Slice’s recent work by examining current advances that combine geometric morphometrics with 3D imaging technology in order to quantify complex morphologies at high resolution using hundreds or thousands of shape variables. But this gain in spatial resolution has a price: Multivariate analyses of these many variables are difficult to interpret and can be computationally challenging; the standard tools of multivariate statistics were not invented for such a vast excess of measurements over cases. The problem is particularly pressing in physical anthropology, especially paleoanthropology, where studies typically exploit many measurements upon small samples. It is just as challenging to relate such morphometric data to other data from biomechanics, behavior, or genomics, especially when those other data are highly multivariate also.

The symposium combines cutting-edge applications of high-resolution morphometrics in biological anthropology and its adjacent disciplines (track A) with novel approaches to the multivariate analysis and integration of high-resolution morphometrics with other complex bioscientific data structures (track B).
