Current Research Projects:
1. Causal effect of loan debt on student outcomes (with Paul Umbach) - an analysis of NCSU's Pack Promise program, in which students at or below 150% of the federal poverty level receive reduced loans. We will be using regression discontinuity and difference-in-difference models to estimate the effect on academic performenace and persistence. It is scheduled to be presented at ASHE in November 2012.
2. Community colleges granting four-year degrees (with Melissa Cominole, a doctoral student) - we will be studying whether allowing community colleges to grant bachelor's degrees actually increases the supply of bachelor recipients, using a panel model.
3. Randomized trials in postsecondary research (with Ashley Clayton, a doctoral student) - a literature review looking at higher education studies that randomize or pseudo-randomize treatments in the field.
4. Some other projects that I am trying to get off the ground this year include a study of the Georgia HOPE scholarship, using panel models; a study of the effect of long-term physical exercise on human capital formation, using IV with a randomized instrument; and a study looking at whether unionization affects faculty productivity, using IV.
Research focuses on measuring student learning in higher education, competency-based education, causal inference with observational data, and survey methods.
