Congratulations Dr. Dunn!

Muriel Dunn successfully defended her PhD thesis “Advancing broadband hydroacoustic methods for ecological surveys with uncrewed vehicles in the Arctic” at Memorial University December 2023. Dr. Dunn was a PhD student at Memorial University, supervised by Dr. Maxime Geoffrey, and co-supervised by CRIMAC researcher Geir Pedersen.

Author: Geir Pedersen

Her PhD work covered the use of broadband echosounders to infer information about arctic fauna based on the broadband frequency response, using ex and in situ measurements, acoustic modelling, and machine learning methods.

Muriel worked at Akvaplan-niva while completing her PhD, and she is now starting a new job at SINTEF Ocean.

IMR and CRIMAC wishes you the best of luck in your new position and look forward to further collaboration in the future!

Two of the papers from her PhD are available online:
