Research Biography

My research focuses on various issues related to statistics and mathematics education. My interest in statistics education grew from my experience working as an assessment specialist at Educational Testing Service where I served as one of the primary test developers for the AP Statistics program. My current research involves the assessment of statistical concepts and the development of resources to impact the way teachers and undergraduate students learn content.
