Selected Projects

The role of physician social networks in the adoption of new prescription drugs

{ Built and analyzed a number of graph based physician social networks based on Pennsylvania Medicare, Medicaid claim data and physicians’ AMA data using SAS/R/Python. Analyze the in

uence of social networks on the adoption of new prescription drugs using Instrumental Variable Regression (STATA).

Physician referral decision: quality or familiarity

{ Constructed a physician referral relationship network. Quantitatively model the familiarity using driving distance and shared organizations (SAS/Google Map API/ArcGIS). Two-stage model was used to compare the impact of quality and familiarity factors on referral relationship (STATA).

Weighted model selection for fractional polynomial models

{ Developed a method for analyses of continuous predictors in Poisson model using fractional polynomial and identify the best set of transformations. Implemented the method based on bootstrap simulation using R.
