Megan Ballard

Senior Research Scientist

Megan S. Ballard is a Senior Research Scientist at the Applied Research Laboratories, University of Texas at Austin. Ballard received a B.S. in Ocean Engineering from Florida Atlantic University 2005 and a Ph.D. in Acoustics from Pennsylvania State University in 2009. Ballard received the A.B. Wood Medal and Prize from the UK Institute of Acoustics in 2021, R. Bruce Lindsay Award from the Acoustical Society of America in 2016, the Postdoctoral Special Research Award from the Office of Naval Research in 2011, and the National Defense Science and Engineering Graduate Fellowship Award in 2006. Ballard is a fellow of the Acoustical Society of America (ASA), the past-chair of Technical Committee on Underwater Acoustics of the ASA, and Editor for the Proceedings of Meetings on Acoustics. Ballard’s research areas are broadly related to underwater acoustic propagation modeling, geoacoustic inversion, and direct measurement of marine sediment properties. Ballard has made important contributions relevant to measurements and modeling of out-of-plane propagation effects, arctic acoustics, and seagrass acoustics.
