<p>In my professional life I'm an independent statistical consultant and methodological researcher.  As a <strong>consultant</strong> I help clients with a variety of statistical methods and related issues (e.g., study planning and reporting).  My <strong>research</strong> interests center primarily around meta-analytic techniques, including (but not limited to) multivariate effect sizes, correlations, functions of effect sizes, and missing data.</p>
