Prof. Richard K. Leach, National Physical Laboratory, UK 

Professor Richard Leach is a Principal Research Scientist in the Engineering Measurement Division at the National Physical Laboratory (NPL) in the UK. Richard is also a visiting professor of the Wolfson School for Mechanical and Manufacturing Engineering, Loughborough University. He obtained a BSc in Applied Physics from Kingston University in 1989, an MSc in Measurement Systems from Brunel University in 1994 and a PhD in Surface Metrology from University of Warwick in 2000. He has been with NPL since 1990 and has current research interests in surface topography measurement, micro-coordinate metrology and low force measurement. Richard is on the European Board of MANCEF, the Institute of Nanotechnology Advisory Board, the International Committee of Instrumentation and Measurement, the EPSRC Peer Review College and several international standards committees. He has over 130 publications in the field of nanometrology and has just published a textbook on the subject, Fundamental principles of engineering nanometrology.   He lectures at Brunel and Nottingham universities. Richard is a Fellow of the Institute of Physics and the Institute of Nanotechnology. 

Do we really know how to measure surfaces?

We are all used to the simple concept of “a surface”. Often referred to as some sort of boundary between a material and its surrounding environment, surfaces can have a profound affect on the way a component functions. For this reason, the quantitative measurement of surfaces has been carried out for many decades and there is a huge range of instruments available. This paper will discuss the concept of a surface, and address the two most common techniques for measuring a surface: contacting styli and optical methods. But why can we rarely get these methods to agree on the measurement of the same surface? Which method gets closest to the “real” surface? The paper will then address the formulation of a mathematical framework in which we may be able to correct most of the systematic errors that are common to surface measuring instruments, and get closer to the proverbial real surface.

Peter S. Ungar, University of Arkansas
Distinguished Professor Peter Ungar is chairman of the Department of Anthropology at the University of Arkansas.  He obtained his BA in Anthropology at Binghamton University in 1985, and his PhD in Anthropology Sciences from Stony Brook University in 1992.  He served as a postdoctoral fellow in the Department of Cell Biology and Anatomy at the Johns Hopkins University School of Medicine 1992-1993, and as a research associate in the Department of Biological Anthropology and Anatomy at the Duke University Medical Center 1993-1995.  He has been at the University of Arkansas since 1995.  His current research interests are in reconstructing the diets and habitats of early humans and fossil mammals, and in developing new approaches to the characterization of microscopic use-wear of teeth, and functional aspects of tooth shape.   He has published more than 100 papers and books, including the recently released Mammal Teeth: Origin, Evolution, and Diversity (Johns Hopkins Press).   Peter is an honorary research fellow of the Institute of Human Evolution at the University of the Witwatersrand in Johannesburg.

Microscopic use-wear on teeth and diets of human ancestors and other fossil mammals.
Paleontologists have recognized for more than half a century that microscopic patterns of tooth use-wear, or dental microwear, can tell us something about the diets of fossil animals.  Because foods have distinctive fracture properties that require specific interactions with opposing tooth surfaces, they lead to different patterns of dental microwear.  For example, bone and nuts tend to cause pitting as these brittle items are crushed between opposing surfaces.  In contrast, meat and leaves result in parallel scratches as opposing tooth surfaces slide past one another when they slice these tougher foods (think of a set of shears).   In this presentation I will provide an overview of dental microwear analysis and its application to reconstructing the diets of human ancestors and other fossil mammals.  I will review early methods for characterizing dental microwear, such as counting microscopic scratches and pits on SEM photomicrographs, and consider their limitations.  Finally, I will discuss a relatively new technique combining white-light confocal profilometry and scale-sensitive fractal analysis for more repeatable, 3D characterizations of dental microwear surface texture.  This approach has already proven very useful for documenting within and between species variation, and has led to new insights into the feeding behaviors of many extinct mammals.
