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

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.

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

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.
