ASPE College of Fellows
Award Description and Purpose
Election to the ASPE College of Fellows is a highly prestigious honor that is intended to recognize and honor those exceptional members of the Society who have made outstanding contributions to the art and practice of Precision Engineering through original research, significant innovations, education and outreach, or service to the profession. Eligibility criteria and guidelines on nominations are available here and new Fellows are announced each year at the Annual Meeting.
ASPE is proud to recognize the following individuals as members of the College of Fellows
Dannis M. Brouwer
Dannis M. Brouwer of the University of Twente is recognized for his original work in the development of novel precision elastic mechanisms, precision motion controls and flexure based robotic systems. His work is exemplified by the folded leaf spring and the infinity flexure, which have added fundamental flexure configurations to the flexure designer’s toolkit.
Eric R. Marsh
Eric Marsh is an expert in machine tool dynamics and spindle metrology. He is both a gifted teacher and a pioneer in the field of axis of rotation metrology who takes particular effort to see his work transferred to the industrial sector. Eric has taught multiple tutorials at ASPE and published the de facto standard text on axis of rotation metrology. He is perhaps best known by virtue of his many past students who as a result of his mentorship have gone on to highly-productive careers themselves within the precision engineering community. Following a long and distinguished career as a professor of mechanical engineering at the Pennsylvania State University, Eric has recently moved into industry full-time with a new position at KLA. Eric earned his doctorate in mechanical engineering from the Massachusetts Institute of Technology.
Jon R. Pratt
Jon R. Pratt of the National Institute of Standards and Technology is recognized for his leadership and technical achievements related to establishing new fundamental standards for the measurement of force and mass; including the electronic kilogram that redefined the fundamental realization of mass from an artifact-based definition to one based on the Planck constant.
Jeffrey W. Roblee
Jeff Roblee is an accomplished technical leader with over forty years of experience in the design, development, and qualification of diamond turning, milling, and grinding machines used in the manufacturing of optical and high-precision surfaces. He is presently the Division Vice President of Technology at Ametek-Precitech where he is responsible for technology development and applications support for Precitech’s ultra-precision multi-axis diamond turning, grinding, grooving, and milling machines. Jeff began his career as a Systems Engineer in the Large Optics Diamond Turning Group at the Lawrence Livermore National Laboratory, and proceeded to technical and managerial positions at Carl Zeiss and Polaroid before ultimately joining Precitech in 2002. He holds a doctorate in mechanical engineering from the University of California at Berkeley with a dissertation on the design of externally-pressurized gas bearings. Jeff continues to develop and share technical findings related to all aspects of ultraprecision optical fabrication.
Theo A. M. Ruijl
Theo A. M. Ruijl of MI Partners is recognized for contributions to ultra-precision machine design. His work addresses numerous areas including thermal effects, high-precision metrology systems, control systems, damping techniques and system architecture in an industrial setting.
Tony L. Schmitz
Tony L. Schmitz of the University of Tennessee – Knoxville is recognized for advancements in the scientific understanding of the effects of structural dynamics on precision machining processes, advancements in displacement measuring interferometry, and numerous other topics critical to precision engineering.
Alexander H. Slocum
Alexander H. Slocum of the Massachusetts Institute of Technology is recognized for developing, teaching, and applying precision engineering principles to machine design, medical devices, and energy systems. His work has resulted in several hundred patents and technical publications, textbooks, and several generations of engineers trained in the principles and practice of precision engineering.
Mark Stocker of Fives’ Grinding is recognized for his outstanding accomplishments in the field of precision systems design that have resulted in over 150 patents from over 40 unique inventions. His application of the basic principles of precision engineering in novel ways has resulted in a wide range of unique high precision manufacturing equipment.
