Research Interests

Margaret’s research uses data science and machine learning to combat human trafficking. Her current projects develop interpretable machine-learning models for detecting and disrupting human trafficking in the illicit massage industry. She uses natural language processing and geospatial analysis, among other techniques, in building prediction models that can be implemented by counter-trafficking stakeholders. In future endeavors, she would like to explore the use of these methods to tackle other global issues.
