I am a statistical consultant at the Cornell Statistical Consulting unit. My background is in mathematics education, particularly in issues of measurement and assessment.

I have taught a variety of statistics courses in addition to courses like probability, linear algebra, and calculus.

I am interested in free and open-source software, especially the statistical language R.
