Robert M. Hochmuth
Professor Emeritus of Mechanical Engineering and Materials Science
Dr. Hochmuth applied the principles of thermodynamics, and solid and fluid mechanics, to biological problems. In particular, he and his colleagues characterized and measured the elastic, viscous and adhesive properties of human red cells and white cells, especially neutrophils. In this work, individual cells were mechanically manipulated with a micropipette. Small suction pressures on the order of 0.1 pN/µm2 and detachment forces on the order of 10 pN were imposed on a cell and displacements at the cellular boundaries as small as 50 nm were measured. His final work before he retired focused on stretching the individual microvilli that exist on the surface of neutrophils, on extracting receptors from the cell's membrane and on measuring the forces of attachment between individual receptors and their antibodies.
Professor Hochmuth became an emeritus professor in Mechanical Engineering and Materials Science, and Biomedical Engineering, on September 1, 2004.
