Research interests
I am interested in understanding systems/cognitive neuroscience through theoretical modeling and analysis of models that range from the biophysically realistic to the more abstract mathematical models, with emphasis on experiments. Currently, I am studying how animals and humans make simple perceptual decisions and their neural mechanisms. These can include selecting an action among competing alternative choices, or even deciding whether or not to make an action. These sensorimotor processes can be influenced not only by external stimuli, but also from factors such as stimulus or performance history, neuromodulation, rewards and learning, ``top-down'' cognitive control and goals.
