Biography:

Ramani Duraiswami is a professor in the Department of Computer Science.

He is the director of the Perceptual Interfaces and Reality Laboratory and has broad research interests in a number of areas, including scientific computing, spatial audio, and machine learning and computer vision.

Duraiswami's work in computer audition is inspired by the way humans effortlessly use spatial sound for making sense of the environment. The focus is on understanding the physical mechanisms, and providing machines with the same capabilities, and the use of computing, mathematical physics and experiments have characterized this work. In scientific computing, the focus is on solving very large problems using approximation algorithms and parallel computing. This work has been driven by applications in audio, speaker ID, computer vision, physics, and machine learning. A particular focus here has been in developing and improving algorithms based on the fast-multipole method, and in the use of heterogeneous multicore architectures to achieve orders of magnitude speed-ups.

Duraiswami received his doctorate in mechanical engineering from Johns Hopkins University in 1991.
