Andrea Vacca is the director of the Maha Fluid Power Research Center, the largest academic research center dedicated to fluid power research in the United States. His research focuses on several aspects of hydraulic control technology including new concepts to perform hydraulic actuations, new designs and modeling of positive displacement machines, electrification of fluid power systems, modeling of the properties of hydraulic fluids, reduction of noise emissions from hydraulic components. His research has been funded by the U.S. Department of Energy, the U.S. Department of Agriculture, the National Science Foundation, and several industry partners (see here for a detailed list of sponsors).

Dr. Vacca holds 18 patents/patent applications and he is author of about 200 technical papers, and of the textbook “Hydraulic Fluid Power”. He is the Editor in Chief of the International Journal of Fluid Power, one of the directors of the Global Fluid Power Society and a former chair of the Society of Automotive Engineers (SAE) - Fluid Power Division and of the American Society of Mechanical Engineers (ASME) - Fluid Power System and Technology Division.

In 2019, Andrea Vacca was awarded the 2019 Joseph Bramah Medal from the Institution of Mechanical Engineers for his contributions to global fluid power research, particularly related to gear pumps.

Andrea Vacca is a fellow of the American Society of Mechanical Engineers (ASME) and he received his Master’s degree in Mechanical Engineering from the University of Parma (Italy) and his Doctoral degree in Energy Systems from the University of Florence (Italy).
