Pictures: A picture of Dalrymple in Thailand, pointing to a tsunami water line. Here's a picture at UD, showing me putting dye into a rip current generated in the Ocean Engineering Laboratory's Directional Wave Basin. This study of rip current generation in the vicinity of sand bars was funded by ONR. Finally, here's a picture from Waves 2001 with Robert G. Dean (my Ph.D. advisor), Leslie Ewing and Becky Edge (K. Barnes photo).

Classical guitar: Here I am with my Antonio Raya Pardo guitar. Here is my Flamenco guitar, made by James T. Kirby, a former student and colleague at the University of Delaware.

My classical guitar instructor is Branimir Krstic, teacher, performer, and composer.
