Ram Sriram is the Chief of the Software & Systems Division in the National Institute of Standards and Technology’s Information Technology Laboratory (ITL). Before joining the Software and Systems Division, Sriram was the leader of the Design and Process group in the Manufacturing Systems Integration Division, Manufacturing Engineering Laboratory, where he conducted research on standards for interoperability of computer-aided design systems. He was also the manager of the Sustainable Manufacturing Program. Prior to joining NIST, he was on the engineering faculty (1986-1994) at the Massachusetts Institute of Technology (MIT) and was instrumental in setting up the Intelligent Engineering Systems Laboratory. At MIT, Sriram initiated the MIT-DICE project, which was one of the pioneering projects in collaborative engineering and documented in the book entitled Distributed and Integrative Collaborative Engineering Design, Sarven Publishers, 2002.

Sriram has extensive experience in developing knowledge-based expert systems, natural language interfaces, machine learning, object-oriented software development, life-cycle product and process models, geometrical modelers, object-oriented databases for industrial applications, health care informatics, bioinformatics, and bioimaging. He has consulted for several leading corporations all over the world. His client list (during his tenure at MIT) included Boeing, GE, NTT Data (Japan), NASA, Xerox Corporation, United Technologies, IIC (Spain).

Sriram has co-authored or authored nearly 275 publications, including several books on Artificial Intelligence. He has published in a wide range of journals in engineering, computer science, and health care fields. The papers he and his group wrote have won many recognitions and awards, including many best paper awards and most cited paper awards. Sriram received several awards including: an NSF's Presidential Young Investigator Award (1989); ASME Design Automation Award (2011); ASME CIE Distinguished Service Award (2014); the Washington Academy of Sciences' Distinguished Career in Engineering Sciences Award (2015);  ASME CIE Lifetime Achievement Award (2016), CMU CEE Lt. Col. Christopher Raible Distinguished Public Service Award (2018), and 2021 IIT Madras Distinguished Alumni Award.

Sriram was a founding co-editor of the International Journal for AI in Engineering (1986). He also served on the Executive Committee of the ASME's Computers in Engineering Division for six years, including as its chair.  Sriram's other professional activities include the following: an associate editor of ACM Computing Surveys and IEEE Transactions on Computers,  co-chair of NITRD's Software Productivity, Sustainability, and Quality (SPSQ) group, President-Elect of the Washington Academy of Sciences,  and federal representative to ONC's Health IT Advisory Committee.  He serves as the chair of the 2021 IEEE Computer Society Fellow Evaluating Committee. 

Sriram is a Fellow of the American Society of Mechanical Engineers (ASME),  the American Association for the Advancement of Science (AAAS), the Institute of Electrical and Electronics Engineers (IEEE), the Solid Modeling Association (SMA),  International Council on Systems Engineering (INCOSE), and the Washington Academy of Sciences (WAS). He is also a Distinguished Member (life) of the Association for Computing Machinery (ACM) and a Senior Member (life) of the Association for the Advancement of Artificial Intelligence (AAAI).
