Professor Ananya Sen Gupta’s research interests lie in signal processing, pattern recognition, and knowledge discovery, with an emphasis on applications to coastal environments and the Earth’s Van Allen radiation belts. She seeks to develop geometric computational techniques that enable sophisticated representation, localization, tracking, and classification of environmental processes. Her algorithms have been applied to shallow water acoustic communications, fingerprinting oil spills, and sonar target recognition in high-clutter coastal environments, as well as to tracking high-energy plasmospheric events on Earth and Mars.
