The PhD defence will be fully digital and streamed directly using Zoom. The host of the session will moderate the technicalities while the chair of the defence will moderate the disputation.
Ex auditorio questions: the chair of the defence will invite the audience to ask ex auditorio questions either written or oral. This can be requested by clicking 'Participants -> Raise hand'.

Main research findings
There is increased activity in the subsea domain, which requires access to robust high-speed communication. Applications range from live video streaming within marine robotics to fish-telemetry in aquaculture. Existing underwater communication solutions are often unable to meet the new and emerging demands. New solutions are required. This thesis aims to improve the data rates in underwater communication, by means of coherent acoustic communication in the very high frequency (VHF) band.
Combined with a 64-hydrophone line array real-time information rates of 465 kbps over 100 m, and 155 kbps over 1000 m is demonstrated in the VHF band. This has been made possible through the work in this thesis.
