Nico Declercq is an associate pro-
fessor at the Woodruff School of
Mechanical Engineering of the
Georgia Institute of Technology in
Atlanta. At Georgia Tech he has a
laboratory in France at Georgia
Tech Lorraine as part of the
French-American international
unit “UMI Georgia Tech – CNRS
2958.” Declercq teaches acoustics
and engineering classes at Georgia
Tech Lorraine and Georgia Tech
Atlanta. He is president of the
2015 International Congress on
Ultrasonics to be held in Metz,
France. Declercq is a European
Union Promodoc Ambassador. He received the International Commission for Acoustics Early Career Award in 2007, the International Dennis Gabor Award in 2006, and a Sigma Xi Young Faculty Award in 2006. Prior to becoming a Georgia
Tech faculty member, Declercq was subsequently a voluntary re- searcher at the laboratory of Oswald Leroy at the Kortrijk cam- pus of the Catholic University of Leuven in Belgium, Ph.D. researcher at Ghent University, and a postdoctoral fellow of the Belgian National Science Foundation. His first collaborations in the United States were with Mack A. Breazeale at the National Center for Physical Acoustics, Oxford, Mississippi. He received a Master’s degree in (astro)physics from the Catholic University of Leuven in 2000 and a
Nico Declercq and his daughter at Chichen Itza
Ph.D. in Engineering Physics from Ghent University in 2005. Declercq is married with 3 children and, although he is a glob- al citizen, his family roots are entirely located in the south of West Flanders in Belgium.
