I am an Associate Professor of Information Systems in the Heinz College at Carnegie Mellon
University, where I have been the H.J. Heinz III College Dean's Career Development Professor.
I also hold courtesy appointments in the Machine Learning Department and Robotics Institute in CMU's School of Computer Science, and an
adjunct appointment in the Department
of Biomedical Informatics at the University of Pittsburgh. I received my
Ph.D. in Computer Science from CMU in 2006. Before that, I received my
B.S.E. from Duke University, M.Phil. from Cambridge University, and M.S. from
Carnegie Mellon. At CMU, I direct the Event and Pattern Detection
Laboratory, and co-direct the Healthcare
Information Technology thrust of Heinz College's iLab.
As of July 1st, 2018, I will be leaving CMU to join New York University,
as Associate Professor of Computer Science and Public Service, in NYU's
Courant Institute Department of Computer Science and Wagner School of
Public Service, and Associate Professor of Urban Analytics, in NYU's
Center for Urban Science and Progress. Please direct all
correspondence to the NYU e-mail address above.
Our pre-syndromic surveillance project was selected as the runner-up in the Department of Homeland Security's Hidden Signals Challenge, a nationwide system design competition which focuses on detecting emerging bio-threats in real time. Here is the link to the winner announcement.
I am guest co-editor of a special issue of GeoInformatica on "Analytics for Local Events and News". Submissions are due August 15th. Please feel free to distribute this call for papers. Note that all papers should be submitted through the Springer GeoInformatica website.
Our rodent prevention work was recently featured in an article on CityLab.
According to the article, "The city of Chicago is still running Neill's predictive analytics approach and has
touted that it's 20 percent more effective than the traditional method of baiting rats after they've been
Our paper on Semantic Scan: Detecting Subtle, Spatially Localized Events in Text Streams was named the
winner of this year's Yelp Dataset Challenge. Our approach for identifying emerging topics can be
used both for public health (detecting "novel" outbreaks with rare or previously unseen symptom patterns) as well as identifying emerging regional
business trends. Thanks to both Yelp and CMU for their very
nice press coverage of this work!
Our crime prediction work with the Pittsburgh Bureau of Police was featured in an editorial in the 30 Sep 2016 issue of
Our comprehensive review article, "Youth violence: what we know and what we need to know", was featured in
a press release by the
American Psychological Association. The article was published in the January 2016 issue of the APA's
flagship journal, American Psychologist, and is available here.
We are grateful to the Richard King Mellon Foundation for their support of our project, "Urban Predictive Analytics for a Safer and Cleaner Pittsburgh", as part of the award, "Metro21: Knowledge-Powered Pittsburgh to Improve Urban Quality of Life". More information on this project is available here.
What can machine learning do for the healthcare industry? Here are some examples from my
own work, presented as part of the UPMC Enterprises "Inspiration, Innovation, and Excellence" talk series. And here is a related summary of our lab's recent work and ongoing projects in
healthcare and other domains.

I am currently teaching four courses at the Heinz College. Course
descriptions, sample syllabi, and lecture slides can be obtained by
clicking on the course names below, and current course materials are
available on Blackboard.
Statistics for IT
Managers (95-796) is the core statistics course for students in the Master
of Information Systems Management program.
Large Scale Data Analysis for Public
Policy (90-866) is a master's level course which focuses on the
application of artificial intelligence and machine learning methods to
real-world policy problems.
I am also teaching two Ph.D.-level seminar courses, intended for doctoral
students (and qualified master's students) from Heinz College, the Machine
Learning Department, and other university departments who wish to engage
in cutting-edge research at the intersection of machine learning and
public policy. The Research Seminar in
Machine Learning and Policy (90-904, cross-listed in MLD as 10-830)
is a half-semester course which covers a broad range of MLP topics.
Special Topics in Machine Learning and Policy (90-921, cross-listed in MLD
as 10-831) is a half-semester course which will explore a single MLP topic
in detail. Topics covered include Event and Pattern Detection
(Spring 2010 and Spring 2014), Machine Learning for the Developing World (Spring
2011), Harnessing the Wisdom of Crowds (Spring 2012), and Mining Massive Datasets (Spring 2013).
I also direct the Joint Ph.D. Program in Machine Learning and
Public Policy, offered jointly by the Heinz College and Machine Learning
Department at CMU. Information about this program is available
My research is focused on novel statistical and computational methods for discovery of emerging events and other relevant patterns in complex
and massive datasets, applied to real-world policy problems ranging from medicine and public health to law enforcement and security.
Application areas include disease surveillance (e.g., using electronically available public health data such as hospital visits and
medication sales to automatically identify and characterize emerging outbreaks), law enforcement (e.g., detection and prediction of
crime patterns using offense reports and 911 calls), health care (e.g., detecting anomalous patterns of care which significantly
impact patient outcomes), and urban analytics (e.g., helping city governments to predict and proactively respond to emerging patterns
of citizen needs).
A more detailed description of my research, updated December 2015, is available here,
and a complete list of publications is available in my CV. Also, please see our new Event and Pattern Detection
Laboratory web site, http://epdlab.heinz.cmu.edu, for the most up to date descriptions of our
ongoing research projects, and links to our publications and presentations.
