My primary research interests lie in the area of Acoustics and Array Signal Processing.
I have worked on many interdisciplinary projects in different areas such as Underwater Acoustics, Acoustical Oceanography,
Bioacoustics, Marine Geophysics, Acoustical Imaging, Room Acoustics, etc.

Array Signal Processing
Array Signal Processing is a research area that uses the data collected by an array of receivers to extract knowledge about the source signal and its location.
In my research, I have worked on source signal reconstruction, sound source localization, and beamforming.
Acoustic signals received by an array of receivers can be used for imaging and sound source localization.
In my research, I have developed a novel beamforming technique which has higher resolution compared to
the existing methods. The main application of this method is cavitation imaging and biomedical imaging.
Earth scientists use active source seismic reflection surveys to image the solid earth and more recently even the water column. For this research, I
studies sound propagation and energy interaction with the ocean bottom.
When an acoustic wave travels in a room, it reflects from the walls and hard surfaces in the room.
So, the recorded signal is distorted by reflected waves from the boundaries. Removing echoes from the recorded signal
is one of the main tasks in room acoustics.
The localization of marine mammals is important for biological studies and for assessments of the impact of anthropogenic activities on the marine
environment. Passive acoustic monitoring (PAM) has become an increasingly popular method for localizing certain marine mammal species that are
acoustically active. I have used both vertical and horizontal hydrophone arrays to find the location of Baleen whales.
