One of the ultimate goals of my investigations is to understand the neural mechanisms underlying adaptive behavior in diverse insects. I work at the level of sensory signals, single neurons at different stages of the sensory pathway, networks of neurons, and behavior. I’ve studied visual and olfactory senses in different insects and their integration and mechanisms of sensory adaptation. I use neurophysiological, morphological, behavioral and chemical ecology techniques in a naturalistic framework. About six years ago I resumed studies in insects which are vectors of human diseases. These studies not only focused on adaptive behaviors and the underlying neural mechanisms, but they also explored basic vector biology issues.
Since recently joining the laboratory of Dr. Kristin Scott at UC Berkeley as an Associate Researcher, my research interests expanded to include the neural mechanisms regulating feeding behavior in the fruit fly Drosophila melanogaster. This superb model organism offers a unique opportunity for such studies, given the fly’s amenability for experimentation and genetic manipulation of identified neuronal cells and neurons.
