Julie Viollaz

Julie Viollaz is a research associate at Michigan State University and works as a consultant on wildlife crime and conservation criminology issues. She specializes in field interventions to help communities and NGOs apply crime prevention techniques to poaching and wildlife trafficking. She was part of the team that conducted the mid-term evaluation of USAID’s Central Africa Regional Program for the Environment (Phase III) in the Congo Basin in November 2016. She has studied the port characteristics that facilitate illegal fishing and mapped the financial crimes committed by wildlife traffickers when trafficking wildlife products.

Julie’s ongoing work includes building a situational crime prevention toolkit for human-carnivore conflict and retaliatory killings, designing an evaluation methodology for anti-poaching interventions, and using statistical modeling to predict the displacement of wildlife crime. She is currently collaborating with GWC to design a community-based conservation crime prevention program in the Annamite Mountains of Vietnam. She has a Ph.D. in criminal justice from the CUNY Graduate Center and John Jay College of Criminal Justice and a B.A. in biology from Mount Holyoke College.
