Background
Began at Tech in Fall 1990 as an Assistant Professor.
Research
Dr. Streator has worked on tribological problems relating to the magnetic disk drive industry, studied fundaments of lubrication and adhesion with nanomete-scale films, and modeled friction induced vibration, simulated microscale, solid-solid adhesion.
A number of technologies, including computer disk drives, and microelectromechanical
systems (MEMS) rely on controlling frictional effects at small length scales.
For example, the memory storage capacity on magnetic disks and the reliability
of micro-motors are both strongly influenced by the development of so-called "stiction" forces,
which become increasingly prominent as things get small. Dr. Streators research
is focused on understanding these and other microscale interactions that
affect friction, lubrication, and wear.
In one project Dr. Streator investigates how nanometer-scale lubricant films
respond under conditions of high shear. Such behavior is important in determining
the magnitude of friction forces experienced in certain  interfaces. In another
project, he is investigating the role of intermolecular adhesive forces
during microscale impact. The results of this study are expected to shed
light on how materials "stick" to one another when they come into contact. In a related study, Dr. Streators group is conducting an experiment to determine the limits of adhesive forces caused by confined liquids. This research is important to modeling the effects of water condensation and other liquid contaminants on interface performance. Dr. Streators research is sponsored by General Motors Corporation, the National Science Foundation, and IBM.
