I
am an associate professor in the department of computer
science and of the University of
Maryland Institute of Advanced Computer Studies (UMIACS). I direct
research at the Perceptual Interfaces and Reality Laboratory (PIRL), and have broad research interests in
computer audition, computer vision and scientific computing.
Audio and Computational Acoustics:
Acoustics for perceptual reality: Head Related Transfer Functions, Room Impulse Responses, Auditory Telepresence, Reproduction of audio using headphones, Reproduction using speakers
Microphone Arrays: Beamforming, Source Localization, Source Modeling, Spherical Microphone Arrays, Cameras and Arrays, The Audio Camera
Auditory User Interfaces: Sonification of Data, Systems for presentation, auditory prosthesis for the visually impaired
Underwater acoustics (older stuff):
Bubble counting, sound propagation in bubbly media and fog
Scientific Computing:
Fast Multipole Methods: Data Structures; Adaptive Algorithms; FMM for the Laplace, Helmholtz, Biharmonic, Maxwell and Stokes kernels; General kernels; Scattering problems
High Performance Computing: GPU Computing, Parallel Computing
Computational Statistics and Learning Methods: Improved Fast Gauss Transform in high dimensions; Mean-Shift mode seeking; Particle Filters; "Fast N-Body Learning"; Classification, Ranking, Gaussian Processes, Data Assimilation.
Data Fitting and Modeling: RBF interpolation; Data Structures for higher dimensional data; Non Uniform Fast Fourier Transforms, Assimilation
Boundary Element Methods: Speedup via the FMM; Computation of singular and near singular integrals; Meshless Methods; Software.
Other (older stuff): Electrical Impedance Tomography; Bubble Dynamics; Free surface flow; Spectral Methods; Effective Media; Inverse problems.
Computer Vision:
Vision aware audio; Tracking; Pose; Kernel methods, Vision based prosthetics for the visually impaired, application of fast algorithms to computer vision and image processing, The Audio Camera.
