Earl J. Wagner is a Postdoctoral Research Associate at the University of Maryland, College Park. He works with Jimmy Lin and Doug Oard on software to help users find documents relevant to their tasks. In particular, he is contributing to Ivory, a toolkit for information retrieval running on Apache's Hadoop, an open-source, Map/Reduce-based framework for cloud computing.

In Fall 2011, he is teaching LBSC 796/INFM 718R: Information Retrieval Systems in the UMD iSchool.

He previously worked with Bank of America, as a Research Affiliate with the Center for Future Banking at the MIT Media Lab where he applied MIT's common sense computing technologies to text analysis tasks in banking.

In December 2009, he completed a Ph.D. in Computer Science at Northwestern University for his work designing and developing Brussell, an intelligent news-situation analysis and presentation tool. Before joining Northwestern, Earl earned an M.S. degree at the MIT Media Lab for his work on Woodstein, a prototype tool for consumers to diagnose problems with e-commerce transactions. He earned his bachelor's degree at University of California, Berkeley studying computer science and philosophy. He has presented and published his work on Brussell and Woodstein in several conferences and workshops, including the Intelligent User Interfaces conference and the AAAI Spring Symposium. He has also spoken about this work at corporations such as IBM, Intel, Microsoft and Mastercard and universities including MIT, NYU, and Berkeley.
