As a member of the Department of Mathematics and Statistics, I work on statistical modeling and analysis of neural recordings across spatial scales. Propagation of electrical and magnetic fields in the brain depends on both static anatomical features and state-dependent dynamical features like coherence, neuromodulation, and active pathways. My work involves constructing models that use strong prior knowledge about these features in specific brain states to bridge spatial scales. Such models can explain apparent discrepancies in signals recorded at different scales and improve our understanding of the micro-scale dynamics that underlie macro-scale biomarkers of pathological states.
