Smruti Ranjan Sarangi is a computer scientist and academic at the Indian Institute of Technology Delhi (IIT Delhi). He is a chair professor in the Department of Computer Science and Engineering at IIT Delhi, where his research includes computer architecture, electronic design automation, computer-aided design (CAD), intelligent systems, and cyber-security.

Education

Sarangi completed a Bachelor of Technology in computer science from the Indian Institute of Technology Kharagpur. He later earned master's and doctoral degrees in computer science from the University of Illinois Urbana-Champaign.[1][2]

Career

Before joining IIT Delhi, Sarangi worked at Synopsys Research and IBM Research Labs.[3] He joined the Department of Computer Science and Engineering at IIT Delhi in 2011 and later held a joint appointment with the Department of Electrical Engineering. He served as head of IIT Delhi's Educational Technology Services Centre from September 2022 to August 2025.[4] He currently serves as the Head of the Computer Services Center.[5]

Sarangi is also the founder of Thought2Design Systems Pvt. Ltd., a company incubated at IIT Delhi.[3]

Research

Sarangi's research is in computer systems, with work spanning computer architecture, operating systems, distributed computing, electronic design automation, and systems security. At IIT Delhi, he directs the SRISHTI research group, whose current research areas include machine learning- and large language model-based design of intelligent systems for software, hardware, IoT, and embedded platforms, as well as security for software, hardware, and IoT systems.

A recurring area of his research has been architectural simulation. Sarangi and collaborators developed Tejas, a Java-based microarchitectural simulator,[6] and later published work on parallel[7] and chunking-based approaches for trace-driven multicore simulation.[8]

His systems-security work includes research on secure execution, control-flow integrity, trusted execution environments, and side-channel attacks. His publications include a survey of hardware-assisted mechanisms for enforcing control-flow integrity,[9] work on cache side-channel countermeasures,[10] and research on secure neural-processing hardware.[11]

Sarangi has also published on IoT systems, optical interconnects, thermal modeling, and hardware acceleration for data processing. His work with Pallavi Sethi surveyed IoT architectures, protocols, and applications,[12] while other publications examined on-chip optical interconnects,[13] chip-level thermal simulation,[14] and hardware acceleration for XML parsing.[15]

Recent work from his group has included applications of intelligent systems to drones,[16] computer graphics,[17] and serverless computing, including publications on drone swarming models, temporal supersampling for graphics, and latency control in serverless platforms.[18]
