Biography
After completing his graduate work Joseph Vignola conducted research at the Naval Research Laboratory in Washington, D.C. His research is focused on structural dynamics and acoustics, MEMS and nanotechnology. This work is laboratory based and principally uses optical measurement systems for studying structural dynamics of micro- and nano-mechanical systems, characterizing physical properties. Over the past five years he has published a number of papers focused on damping mechanisms in micro-systems. Additionally, he has studied nondestructive testing of large-scale systems such as aircraft and submarine structures as well as frescos at the U.S. Capitol.
