Who is John Fisher?

The paper we’ll look at today is a review of much of the work of John Fisher, et al., from the Institute of Medical and Biological Engineering, University of Leeds, Leeds, United Kingdom. Much of Fisher’s career has been directed toward the study of the tribological behavior of total joint (hip) replacement bearing surfaces. Specifically, he has examined the wear behavior of these bearings and corresponding biological activity (osteolytic behavior) of wear debris produced by materials such as highly cross-linked polyethylene, alumina, cobalt-chromium alloy, and CrCN coatings.

John Fisher currently holds the following titles at the University of Leeds: Professor of Mechanical Engineering, Pro-Vice-Chancellor for Research, Director of the Institute of Medical and Biological Engineering, Director of BITE Centre for Industrial Collaboration, and Leader of the Biomedical Engineering Research Group in the School of Mechanical Engineering.

Introduction and Importance of Capturing and Separatation of Polyethylene Wear Debris

I found this manuscript a few weeks ago after noticing a news release about the topic and the first author Donna Meyer. Donna is an assistant professor at the University of Rhode Island in the Department of Mechanical Engineering and Applied Mechanics. She indicates her funding sources for this study to be NSF and NIH grants.
