My five years at the US GAO were foundational for my future work. I served on the Forensic Audits in Investigative Service (FAIS) team, which is primarily dedicated to using innovative data collection and analysis techniques to identify fraud, waste, and abuse in government programs. The team was also charged with identifying internal control failures and gaps and making recommendations to executive branch agencies to prevent future abuse and recoup lost money and resources. Some of my favorite engagements that I worked on are described below.

Data mining to identify vulnerabilities in availability of controlled drugs

I led the initial engagement to identify vulnerabilities that can lead to the diversion of controlled drugs by conducting analysis of Drug Enforcement Agency (DEA) data. My chief goal was to identify individuals licensed to prescribe controlled substances who are at a high risk of committing fraud and abuse. For example, active prescribers were found who were dead, incarcerated for drug-related felonies, listed in sex offender registries, and whose identities could not be verified.
