PROFESSIONAL EXPERIENCE
Research Economist Intern, RTI International (Durham, NC)
Behavioral Health Economics Program
Summer 2014 through Present
• Conduct data analyses to study the effectiveness of SAMHSA’s screening, brief intervention, and referral to treatment grant program for harmful alcohol and illicit drug use.
• Research and propose methodological approaches to be used to estimate the social costs of alcohol
consumption associated with disease incidence.
• Develop a flexible extension of an existing method used to estimate a probability distribution over
alcohol consumption that accounts for underreporting in survey data.
• Study the sensitivity and specificity of alcohol screening instruments and the role that the cost of
misclassification plays in an optimal screening and brief intervention protocol.

WORKS IN PROGRESS
“Medicare Part D and the Use of Hospital Services”
(Job Market Paper)
I conduct an empirical analysis to determine whether changes in health explain the negative relationship
between Part D and hospital utilizations. Results indicate that Part D reduced overnight hospital stays among
beneficiaries that had limited or no pre-Part D drug coverage, but not among beneficiaries that had generous
pre-Part D drug coverage. The results also indicate that Part D reduced hospital nights among beneficiaries
that had limited or no pre-Part D drug coverage as well as among beneficiaries that had generous pre-Part D
drug coverage. The evidence suggests that these relationships are only minimally explained by changes in
health.
