David studied with Jon Kaas in the Psychology Department from 1995-2001, during which time he published a remarkable series of papers that clearly demonstrated that a visual area under contention, V3, was a component of the visual system of all primates. He also participated in, or was responsible for, a number of other research papers with important findings. He wrote one of the best reviews of visual system organization and evolution in an important 4-volume series The Evolution of Nervous Systems, Elsevier, 2007.  He is the only person to have won two awards from the Cajal Club for research. He received further training in two major research laboratories, with Mriganka Sur at MIT, and with Ed Callaway at the Salk Institute. In 2006, he was hired as an Assistant Professor of Anatomy and Neurobiology at the University of California, Irvine, and in 2007 he also received an appointment in the Department of Cognitive Sciences. David has a most impressive series of publications in the major neuroscience journals. The publications address a range of topics, and are based on some of the most powerful, yet difficult, of modern neuroscience methods. He has more papers coming out of all three laboratories where he trained, and his Irvine laboratory is fully functional where he is now training graduate students and producing new results.
