My research interests are in the area of categorical data analysis.
Many biomedical studies involve outcomes which are qualitative in nature.
This type of analysis is useful, for example, when studying rater agreement and social mobililty data. I am currently collaborating on several projects with the Regenstrief Institute. The intention of one study is to assess whether the use of computerized reminders influences physician practices. The other involves determining whether or not the availability of detailed reports on Emergency Room patient history lowers ER costs and improves patient care.
