About

Jim Preisig is a leading figure in underwater acoustic communications and networking, whose work has advanced the reliable transmission of data through one of the most challenging environments on Earth. His research centers on the physical and data-link layers of underwater networks, with a focus on adaptive signal processing, channel modeling, and system design for high-latency, bandwidth-limited acoustic channels. Preisig’s contributions include pioneering algorithms for equalization and Doppler compensation that have become foundational in the field, enabling more robust communication for autonomous underwater vehicles and ocean monitoring systems. As a key organizer of the Fourth ACM International Workshop on UnderWater Networks (WUWNet 2009), he helped shape the community’s early direction, fostering collaboration between engineers and oceanographers. His work has been cited over 4,000 times, reflecting its lasting influence on both theoretical research and practical deployments. A former Senior Scientist at Woods Hole Oceanographic Institution, Preisig’s legacy lies in bridging the gap between signal processing theory and the harsh realities of underwater propagation, making him an essential reference for any student or researcher exploring the frontiers of subsea connectivity.
