Summary of my work

My work involves the statistical analysis of functional magnetic resonance imaging (fMRI) data. My current interests are in calculating power for group fMRI studies.

Tools

• The fmripower tool! A matlab-based application for calulating power for future group fMRI experiments based on similar, older FSL anlayses.

Papers/Guides

• Linear Contrast Use: This tutorial explains how linear contrasts work and how the resulting hypothesis tests may be misleading. The document also contains R code for recreating the illustrations on your own.
  
  
• Guide for Calculating Percent Change with Featquery: This guide describes how featquery calculates percent change and how for certain types of studies a different procedure is necessary to calculate interpretable percent changes.
  
  
• Modeling Group fMRI Data. (Mumford JA & Poldrack RA (2007). Modeling group fMRI Data. Social Cognitive and Affective Neuroscience 2: 251-257).
