Personal profile

Research interests

Clinical and research interests include multiple areas of epileptology including semiology of epileptic seizures, and neuro-imaging changes in patients with epileptic seizures. Interests in semiology (interpretation of signs and symptoms) of epileptic seizures include clinical changes, such as changes in consciousness, during and after seizures. Neuro-imaging interests incorporate use of magnetic resonance imaging (MRI) and application of analytical techniques such as computational anatomy and general pattern theory to outline brain structures, and use of functional MRI techniques to assist in diagnosis and assess different types of epilepsy. Research in neuro-imaging also involves single photon emission computed tomography (SPECT), which allows measurement of brain cerebral blood flow perfusion during seizures, which correlates well with the electrographic pattern of epileptic seizures. Interests in SPECT scanning include use of computer-aided methods of post-image acquisition processing of ictal and interictal SPECT images, to assist in localization of seizures.
