Dr. Timothy Duda, Senior Scientist in the Applied Ocean Physics and Engineering Department, is an ocean acoustician and physical oceanographer. Dr. Duda received his BA degree in physics from Pomona College and his PhD degree in oceanography from UC San Diego (Scripps Institution of Oceanography). He has led the design, fabrication, or assembly of physical oceanographic measurement systems beginning in graduate school in 1979 (Cartesian Diver, Micro Sampling Sled, Webb Shearmeters, LocoMoor, DIMES Shearmeters). He has collected and analyzed acoustic data from multiple experiments in deep and shallow water over the last few decades, and has devised theories to explain complex underwater acoustic behavior. He is also a developer of three-dimensional (3D) underwater acoustic propagation models and an experienced user of 2D and 3D acoustic propagation models. Most recently he has led a diverse multiple-PI DoD MURI program in coupled ocean dynamical and ocean acoustic modeling, and works actively on ocean acoustic effects and situations that are strongly influenced by rapidly evolving water-column events and complex bathymetry.
