Research Areas

  • Stochastic signal processing
  • Wireless sensor networks
  • Decentralized Bayesian estimation
  • Particle filtering
  • Bayesian performance bounds (Sequential Weiss-Weinstein bounds)
  • Numerical approximations of (stochastic) partial differential equations

Indoor localization of an acoustic source in a wave field:

  • Localization of an acoustic source in a 2-D hallway (left/right: walls) utilizing 8 sensors aligned close to the walls. The algorithm employs the  physical structure. One goal is to partion the region into different clusters and to apply a decentralized algorithm.
