Sampling & Statistics
Research on the optimization of statistical criteria in neuroimaging developed rapidly, with close collaboration with the late professor Keith Worsley, who introduced the Random Field Theory in neuroimaging–a pioneering approach for addressing the problem of false positives and multiple comparisons.
Current research seeks to adjust the statistical detection power with regards to the multi-scale organization of the brain and to refine the statistical criteria based on a priori assumptions about the “building blocks” of the brain’s functional anatomy.
