I have 25 years of experience, and specialize in the field of thin films with specific knowledge in the areas of sputter deposition, thin film contamination and atomic oxygen degradation. I have published on such topics as solar cell materials, optical materials and volatile contaminant materials. I am technical consultant to the aerospace industry, where I have solved a critical issue pertaining to thin film contamination of satellites, and provided an understanding of the atomic oxygen degradation of magnesium fluoride that has led to a change in flight materials
