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.


May 2017: The group is giving four talks (Haiquag Niu, Santosh Nannuru, Mike Bianco, Peter Gerstoft) at the workshop Big Data and The Earth Sciences: Grand Challenges Workshop .

April 2017: Teaching Machine learning for physical applications in the spring quarter.

April 2017: Gave an invited talk at Seismological Society of America's meeting on Using Graph Clustering to Locate Sources within a Dense Sensor Array .

March 2017: We have 3 presentations at the International Conference on Acoustics, Speach and Signal Processing ICASSP.

December 2016: Peter Gerstoft and Jie Li are giving a month-long class at Zhejian University, China, on Priciples of Underwater Acoustics.

November 2016: We have 4 invited talks, and 4 regular talks at Acoustical Society of America Fall meeting.

September 2016: Mike Bianco qualified. Congratulations!

August 2016: Peter Gerstoft and Peter Bromirski published a paper in Science.

June 2016: Mark Wagner qualified. Congratulations!

March 2016: Zhao Chen qualified. Congratulations!

Novenmber 2016: Zhao Chen and Anja Diez installed seimometers on the Ros Ice Shelf, Antarctica.Background webpage and blog

October 2015Post Doc Haquiang Niu and Visiting Student Jie Li joined the group. Welcome!

September 2015: 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.
