About
Dr. Maass’s research focuses on advancing operations research methodology to improve applicability to social justice, access, and equity issues within human trafficking, mental health, housing, and food justice contexts. Her recent research includes determining how to most effectively allocate limited resources to disrupt human trafficking networks, increase access to services for human trafficking survivors, and assess the efficacy of coordination among anti-human trafficking stakeholders. Dr. Maass’s research is supported by multiple federal grants, centers interdisciplinary survivor-informed expertise, and has been used to inform policy and operational decisions at the local, national, and international levels, including being featured in the 2019 United Nations Report of the Special Rapporteur on Contemporary Forms of Slavery.
In addition to her role as an Assistant Professor in the Department of Mechanical and Industrial Engineering, she leads the Operations Research and Social Justice lab at Northeastern University and holds a research appointment with the Information and Decision Engineering Program at Mayo Clinic. She is a recipient of multiple awards, including: the INFORMS Judith Liebman Award, Industrial Engineering Professor of the Year at Northeastern University, NSF Graduate Research Fellowship Program Award, the INFORMS Section on Location Analysis Dissertation Award, and was named a ‘Rising Star’ among INFORMS’ Powerful, Pragmatic Pioneers. Dr. Maass currently serves on the INFORMS Subdivision Council, as INFORMS Section on Location Analysis Secretary, and as an INFORMS Diversity, Equity, and Inclusion Ambassador. She is also a member of the H.E.A.L. Trafficking Research Committee and the U.N. University Delta 8.7 Markets Working Group on Human Trafficking.
