Ethungshan Shitiri is a researcher in wireless and molecular communication systems whose work focuses on intra-body nanoscale communication for in vivo diagnostics and real-time health monitoring. He is with the Nanonetworking Center in Catalunya at the Universitat Politècnica de Catalunya, Barcelona, where he works on human-body and intra-body nanoscale communication research. He is an EU Marie Skłodowska-Curie Actions Postdoctoral Fellow.

He received the B.E. degree in Electronics and Communication Engineering from Thanthai Periyar Government Institute of Technology in 2006, the M.Tech. degree in Communication Systems from Christ University in 2013, and the Ph.D. degree in Information and Communication Engineering from Kyungpook National University in 2018. From 2018 to 2023, he held postdoctoral research positions at the IDEC Center and the Electronics and Electrical Engineering Advancement Institute at Kyungpook National University. In 2025, he was a Visiting Scholar at the Norwegian University of Science and Technology, Trondheim, Norway, and was hosted at the Intervention Center, Oslo University Hospital, where he worked with Ilangko Balasingham’s group.

His research interests include intra-body nanoscale communication, molecular communication, biomarker sensing in the bloodstream, resource allocation, synchronization, handshaking protocols, and multiple access techniques across cellular, machine-to-machine, underwater acoustic, and nanoscale communication systems. He has published more than 25 papers and has secured more than €0.5 million in competitive research funding through international and national projects. His distinctions include the 2024 Marie Skłodowska-Curie Actions Postdoctoral Fellowship, the 2021 Best Paper Award at the KICS Fall Conference, the 2018 Outstanding Thesis Award from Kyungpook National University, the 2016 KNU-Qualcomm Paper Innovation Award, and the 2014 KNU Honors Scholarship.
