  • Dilan Cruz-Flores and Parshva Patel’s summer work on a hand gesture recognition device.
  • Alex Castro’s (P. Abshire’s group at Univ. Maryland) paper on rotor-induced airflow for odor sensing with quadcopters.  (Sensors 2020 Conference)
  • Chenxi Wen’s work on power-law compression of echoes to improve the range over which biological models of angular localization (ILD) will work properly.  This is based on models of the LSO that compute ratios based on balanced excitatory and inhibitory synaptic conductances.

Checkout in Journal Articles:

  • Chenxi Wen’s work on a curved version of the ‘Openspace’ navigation neural network.  This work is exciting because it incorporates an attentional search mechanism tied with a memory system and makes decision in the motor action space, all using spike-timing-based representations.
  • Liuxian Zhao’s latest paper on acoustic metamaterials for ultrasonic sensors (JASA Express Letters)
  • Melanie Anderson’s (T. Daniel’s group at Univ. Washington)  work on a bio-hybrid odor-guided autonomous palm-sized air vehicle.  (Bioinspiration and Biomimetics Journal)
  • Jacob Isbell’s work on hypothetical “echo view cells”, two different neural networks that learn to recognize environmental echo patterns to recognize “places”.
