I am a 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, machine learning and scientific computing. (CV)

GPUML (Accelerating Machine Learning algorithms on the GPU)Non-negative Least Squares on GPU and Multi-core
Several Fast Multipole Method based products are
sold by Fantalgo
The fast multipole accelerated boundary element solver in the ESI-Group VA-One product is based on software developed by Nail Gumerov and myself.
A comprehensive toolkit for audio-visual scene analysis is under development by VisiSonics.
I am a member/affiliate of the following departments, programs and centers, all at the University of Maryland, College Park.
Vice Chair, IEEE Signal Processing Society, Washington DC
I am an ad hoc reviewer for several journals and conferences.
Our book: Fast Multipole Methods for the Helmholtz Equation in Three Dimensions (The Elsevier Electromagnetism Series) was published by Elsevier
