In 1981, Gupta joined the faculty of Physics and Astronomy at Washington State University and was shortly promoted to Full Professor. and served as Chairman of the APS Topical Group on Shock Compression of Condensed Matter. Afterward, Gupta became the founding director of the WSU Institute for
Shock Physics which was established in 1997 with a $10 million grant from the
U.S. Department of Energy. As a result of his academic achievements, he earned the 2001 Shock Compression Science Award from the
American Physical Society for "his contributions to understanding condensed matter and nonlinear physics through shock-wave compression." In 2005, Gupta was promoted to a Regents Professor in the Department of Physics and Astronomy for his "sustained accomplishment in teaching, scholarship and public service." He also received the 2005 Eminent Faculty Award for his contributions to shock-wave compressions and was named to a National Research Council committee on body-armor testing. In 2007, Gupta co-published
Stiff Response of Aluminum under Ultrafast Shockless Compression to 110 GPA with Raymond F. Smith, Jon H. Eggert, Alan Jankowski, Peter M. Celliers, M. John Edwards, James R. Asay, and Gilbert W. Collins. The following year, Gupta and researchers at WSU's's Applied Sciences Laboratory received an $8.5 million research contract to "develop and demonstrate reactive materials to be used in a new generation of national security applications". In 2013, Gupta received the Distinguished Faculty Award from WSUs College of Arts and Science. In 2015, Gupta was recruited by the
United States Army to construct lighter yet still protective body armor for its soldiers. He also received his second WSU Eminent Faculty Award. The following year, he led a team of researchers in watching a material change its crystal structure in real-time, leading to a new concept of discerning the makeups of various materials. ==References==
