Wilson Hernández

Ph.D. candidate

I am a Ph.D. candidate in the Department of Criminology at the University of Pennsylvania. I hold a master's from the École des Hautes Études en Sciences Sociales (Paris) and a degree in Economics from the Universidad de Lima, Peru. I am also a researcher at GRADE, a leading Peruvian think tank.

My research evaluates crime prevention initiatives, focusing on policing, place-based interventions, drug markets, and gender-based violence, primarily through experimental and quasi-experimental designs.

My current work includes studying human mobility (cellphone data) as a mechanism for place-based crime prevention, the effect of policing on drug markets, and the impact of Fentanyl Test Strips on the US opioid crisis.

In Peru, my agenda centers on: (1) capacity building at the police station level for hotspot solutions, (2) the impact of extortions and state-driven responses, and (3) systemic interventions to reduce gender-based violence through national reforms and community-led projects.

(Third-party unrequested editing: Wilson also has two kids, Ana and Fabian. Wilson goes biking with Ana and plays soccer with Fabian. Wilson also eats a lot of chocolate. Especially when it is dark chocolate).
