After sorting through hundreds of photos of S&T's people, programs and events spanning the past twenty years, we've selected a few of our favorites to share in our 20th anniversary photo gallery. We hope these images portray the spirit of innovation and commitment to finding solutions to the hard problems that have been the hallmarks of S&T from early days through today.
If you have a favorite photo from S&T that you'd like to share, send the image file and caption to: stwebpublishing@hq.dhs.gov.
