My research interests are at the intersection of computational neuroscience, information/communications theory and systems biology.
In silico, my focus is on time encoding and information representation in sensory systems, and, spike processing and neural computation in the cortex. In this work, I investigate rigorous methods of encoding information in the time domain as well as massive neural computation algorithms in the spike domain. Furthermore, I am interested in genetic, structural, functional, and plasticity principles of the olfactory system in mammals and simple invertebrates.
In vivo, my focus is on the olfactory system of the drosophila. My current work primarily addresses the nature of odor signal processing in the antennal lobe of the fruit fly.
