The group focuses on physics-based signal processing mostly using just weak noise as a source. We have demonstrated this in ocean acoustics, seismology, and radar. For more details see Publications.


Peter visited China in September 2015, mostly staying at University of Science and Technology of China in Hefei working with Professor Huajian Yao . He also gave talks at Institute of Acoustics, State Key Laboratory of Acoustics in Beijing hosted by Professor ZHANG Renhe. and at Institute of Geophysics, Chinese Academy of Sciences,in Wuhan hosted by Professor Sidau Ni.


Peter was in Antarctica November 2014, and Zhao and Anja followed in Antarctica November 2015.
