Projects

Information Disclosure in Healthcare

I evaluated the impact of Sunshine Act, which was enacted in 2013 and required pharmaceutical companies to report payments to physicians. My current focus is on the impact of information disclosure on payments by Big Pharma and physician's prescribing behaviors.

Online User-Generated Content

I studied the mechanism under which online product reviews created by different online identities and hosted by different platform collectively influence online customer decisions, using Amazon and CNET product review and product popularity data. 

Gender stereotypes on the Internet

I studied people's different reactions to angry and anxious women than to men with the same emotion in online review community. 

Online Review Manipulations

I studied the impact of online fake product reviews on product sales and deepened the understanding of malicious attack behaviors by proposing a novel iterative review attack strategy.

Appointment Scheduling Optimization

I proposed an innovative appointment strategy by jointly optimizing appointment window and reminder sending time, to in presence of appointment no-shows. 

E-commerce Long Tail

I studied the long tail phenomena in e-commerce, and identified that the abundance product variety and online user reviews interact to contribute to this emerging pattern in customer preference.
