My research covers two distinctly different areas: Thin film deposition and materials characterization, and the physics of golf.
Thin film deposition and materials characterization:
A thin film is a layer of a material ranging in thickness from a monolayer (one atom think) to several micrometers (which is still pretty thin!). Thin films are used in many applications; hard wear protective coatings on tools and machine components, anti-reflective coatings in optical applications, magnetic coatings in hard drive memories, and electric materials for semiconductor applications, just to mention a few.
I use technique called magnetron sputtering to deposit thin films, and my research is concerned with controlling the structure and properties of the thin films and how they relate to deposition conditions, such as pressure, temperature, gas composition, ion flux and ion energy.
