President and Governing Board

The Gear Research Institute is governed by a tripartite board of trustees representing the membership of the Institute, the American Society of Mechanical Engineers (ASME) and the American Gear Manufacturers Association (AGMA). Each research bloc creates its own steering committee whose responsibility is to select and guide programs within a bloc.
