Kaduchak was recognized for creating a noninvasive chemical-agent sensor by expanding on a previously developed swept-frequency acoustic interferometer. Kaduchak was one of seven individual recipients. The 2002 Distinguished Performance Award winners are featured in this week's Los Alamos NewsLetter. Photo by LeRoy N. Sanchez, Public Affairs
