Narayanan Rengaswamy is a tenure-track assistant professor of Electrical and Computer Engineering at the University of Arizona. He also works at the NSF Engineering Research Center for Quantum Networks (CQN) in the university.

From September 2020 to August 2022, he was a postdoctoral research associate with Bane Vasić in the Department of Electrical and Computer Engineering at the University of Arizona. He completed his Ph.D. in Electrical and Computer Engineering at Duke University in May 2020, under the supervision of Henry Pfister and Robert Calderbank, and continued there as a research associate until September 2020. His dissertation was centered on error correction techniques for fault-tolerant quantum computing and quantum communications.

Earlier, he obtained his M.S. in Electrical Engineering from Texas A&M University in Dec. 2015, where he was advised by Henry Pfister and Krishna Narayanan for his thesis on polar codes. During the summer of 2015, he was a graduate research intern at Alcatel-Lucent Bell Labs, Stuttgart, Germany, where he worked on spatially-coupled low-density parity-check codes with Laurent Schmalen and Vahid Aref. He received his B.Tech. in Electronics and Communication Engineering from Amrita University, Coimbatore, India in June 2013.

His current research interests are classical and quantum error correction, quantum computing, quantum networking, and quantum communications. He is a reviewer for several journals and conferences. He served on the Posters Program Committee of the 2022 International Conference on Quantum Computing and Engineering (QCE22). He is a Member of the IEEE.
