Biography
David received a BS in Mechanical Engineering from the University of Illinois at Urbana-Champaign (1990) and a PhD in Neuroscience from Northwestern University (2001). He was a Post-doctoral Associate in the lab of Dr Richard Fay at the Parmly Hearing Institute at Loyola University of Chicago from 2001 to 2003 and a Research Associate in the lab of Arthur Popper at the University of Maryland from 2004 to 2008. David was a staff scientist and engineer at Marine Acoustics Inc from 2008 to 2011 before becoming a senior scientist at JASCO Applied Sciences in 2011. He has been a NSFco-investigator (2006-present) and collaborator with Sisneros and his lab since 2003.

Research Interests
David's research interests are diverse ranging from sensory neurobiology to physical acoustics and from computional modeling and signal processing to instrumentation. He is active in a number of research projects including a NSF funded project directed at exploring how fish use sound to understand and navigate their environment. As a staff scientist/engineer he provides environmental risk assessment for marine operations, including sonar, seismic exploration, and construction and operation of alternative energy devices.
