Peter Sigray

Peter Sigray is a Researcher at the Royal Institute of Technology (KTH) in Stockholm, Sweden, affiliated with the Department of Aerospace/Motion Mechanics/MSY within the School of Engineering Sciences. He is based at Technology Ring 8 and teaches the course Underwater Technology (SD2709).

His research spans marine electromagnetism, bioacoustics, and underwater robotics. He previously studied ocean currents using trans-Atlantic cables via motional induction and contributed to the global BIAS project on marine soundscapes. He has developed novel instruments such as the particle motion sensor and the SEMLA electromagnetic sled, the latter used in collaboration with the University of Rhode Island. His current work focuses on underwater communication for AUVs.

He chairs the European Commission’s Technical Group of Underwater Noise (TG Noise), supporting marine policy under the Marine Strategy Framework Directive. In 2024, he will become Director of the Swedish Maritime Robotic Laboratory (SMaRC2.0), highlighting his leadership in marine robotics and environmental monitoring.

His research interests include marine acoustics, bioacoustics, underwater sensing, electromagnetic field mapping, autonomous systems, and environmental instrumentation. Though no publications or students are listed, his technical innovations and policy roles underscore his impact in marine science and engineering.

He has no listed scientific awards. There is no indication of part-time status, retirement, or former staff status.

He leads and contributes to major initiatives in underwater noise assessment and maritime robotics, positioning him at the forefront of applied marine technology and environmental monitoring.
