From 1995-2000 he was with AT&T Labs-Research, Florham Park and AT&T Bell Labs, Murray Hill--first as a Senior Member and later as a Principal member of its Technical Staff. Currently, he is a Professor at the Signal and Image Processing Institute of USC's Electrical Engineering department and holds joint appointments as Professor in Computer Science, Linguistics, Psychology, Neuroscience and Pediatrics. He is also the inaugural director of the Ming Hsieh Institute at USC. He was a Research Area Director of the Integrated Media Systems Center, an NSF Engineering Research Center at USC, and was the Research Principal for the USC Pratt and Whitney Institute for Collaborative Engineering, a unique partnership between academia and industry (2003-2007).Shri Narayanan is a Fellow of the Acoustical Society of America (ASA), the Institute of Electrical and Electronics Engineers (IEEE) and the American Association for the Advancement of Science (AAAS). He is a member of Tau Beta Pi, Phi Kappa Phi and Eta Kappa Nu. He holds the first Viterbi Professorship in Engineering at USC. He is a recipient of an NSF CAREER award, USC Engineering Junior Research Award, USC Electrical Engineering Northrop-Grumman Research award, a Mellon award for mentoring excellence, a USC Distinguished Faculty Service Award, an Okawa Research Award, IBM Faculty Awards (2008, 2010), the 2011 UCLA Engineering Alumni Professional Achievement Award, and a faculty fellowship from the USC Center for Interdisciplinary research. He is a recipient of an Engineer's Council 2015 Distinguished Engineering Educator Award, a Ten Year Technical Impact Award from the 2014 ACM ICMI, a 2009 Best Transactions Paper award (with Chul Min Lee) and a 2005 Best Transactions Paper Award (with Alexandros Potamianos) from the IEEE Signal Processing society and was selected as Signal Processing Society Distinguished Lecturer for 2010-2011 and the International Speech Communication Association (ISCA) Distinguished Lecturer for 2015-16. Papers co-authored with his students have won awards at Interspeech2014-Cognitive Load Challenge, Interspeech2013-Paralinguistics Challenge, Interspeech 2013, Interspeech2012-Speaker Trait Challenge, Interspeech2011-Speaker State Challenge, InterSpeech 2010, InterSpeech 2009-Emotion Challenge, IEEE DCOSS 2009, IEEE MMSP 2007, IEEE MMSP 2006, ICASSP 2005 and ICSLP 2002. His research interests are in signals and systems modeling with an interdisciplinary emphasis on speech, audio, language, multimodal and biomedical problems and applications with direct societal relevance. His laboratory is supported by federal (NSF, NIH, DARPA, ONR, Army and DHS) and industry grants. He has published over 600 papers and has 16 granted U.S. patents.
