I’m interested in using data and analytics for high impact social good problems in areas such as criminal justice, education, healthcare, energy, transportation, economic development, and public safety.
I am the Director of the Center for Data Science and Public Policy, Research Director and Senior Fellow at the Computation Institute and a Senior Fellow at the Harris School of Public Policy at the University of Chicago.
What I used to do: Chief Scientist at Obama for America 2012 campaign focusing on analytics, technology, and data. Senior Research Scientist and Director of Analytics research at Accenture Labs where I led a technology research team focused on applied R&D in analytics, machine learning, and data mining for large-scale & emerging business problems in various industries including healthcare, retail & CPG, manufacturing, intelligence, and financial services.
In my ample free time, I advise several analytics start-ups and non-profits, speak at, organize and participate in academic and industry analytics conferences, and publish in machine learning and data mining conferences and journals.
Historically, my research has spanned from general machine learning and data mining to privacy preserving data mining, text mining, semi-supervised learning, active learning, information retrieval, Natural Language Processing, and knowledge management. Most of my work has focused on developing and using machine learning & data mining approaches to solve large-scale problems in corporate, political, and non-profit areas.
My current interests lie at the intersection of Machine Learning, Public Policy, and Social Sciences. I’m interested in solving large-scale and high impact social problems using data driven and evidence based methods. A lot of government, civic, and non-profit organizations are realizing the value of better data and have been focusing on improving data collection and data standardization. My goal is to build on these efforts, and work with these organizations to use this data to help improve outcomes. My work involves developing and using machine learning and social science methods that can be operationalized to solve policy and social challenges.
My current projects include:
- working with police departments to build Early Intervention Systems that can help identify officers (and dispatches) at risk of adverse interactions with the public
- working with public health departments to do preventative lead inspections and reduce lead poisoning in children
- working with cities to improve home inspection processes to for early blight detection (and prevention) and/or to improve code compliance and health and safety violations in rental properties.
- working with jurisdictions to combine criminal justice, homelessness, mental health, and medical data to identify people in need of social services and public assistance programs and prevent future incarceration
- working with school districts to identify students in need of extra support to achieve different educational outcomes (high school graduation for example)
- developing and teaching a training program in “Applied Data Analytics for Public Policy” for government agencies, foundations and non-profits.
