Research Interests

My research focuses on multivariate physiological brain responses (e.g. LFP, fMRI and EEG) and biologically inspired network modeling techniques to uncover insights into brain function. In addition to exploring the functional neuroanatomy of the visual system, my interests extend to applied biomedical research for social good and fostering inclusive sustainable ecosystems.
