Ryan M. Katona
Research & Development
Biography
Dr. Ryan M. Katona is a materials scientist at Sandia National Laboratories. His research focuses on materials degradation through various electrochemical processes including corrosion and stress corrosion cracking. As an undergraduate studying physics and mathematics, he conducted computational research utilizing molecular dynamics and conducted experiments exploring defects in additively manufactured metals. In his graduate studies at the University of Virginia (UVA), he researched atmospheric corrosion of austenitic stainless steels informing on the potential for long term materials degradation. During his time at UVA, he was also an undergraduate intern at Sandia National Laboratories. As a postdoctoral researcher at Sandia National Laboratories, he set-up and led experimental efforts for stress corrosion cracking testing.
