I am a graduate student working in acoustics and electrical engineering at the Johns Hopkins University in Baltimore, Maryland. My doctoral research focuses on speaker and microphone array processing for immersive telecollaboration. My work is done under the direction of James West and funded by a NSF grant on Immersive Acoustics for Multi-channel Multi-party Telecollaboration in conjunction with Fred Juang’s Lab at the Georgia Institute of Technology. My research interests include microphone and loudspeaker arrays, MEMS devices, acoustic signal processing (MIMO, multiresolution, and adaptive algorithms), noise reduction, beamforming, dereverberation, source separation and localization, and echo cancellation.
