Brendan T. O'Connor
I am an assistant professor in the
College of Information and Computer Sciences
at University of Massachusetts, Amherst
(since Fall 2014).
I am affiliated with the
Computational Social Science Institute,
the Initiative in Cognitive Science,
the Centers for
Data Science and
Intelligent Information Retrieval.
Teaching, current and past:
See the SLANG Lab page.
What can statistical text analysis tell us about society?
that can help answer social science
I'm interested in
statistical machine learning and
natural language processing,
especially when informed by or applied to areas like
political science or sociolinguistics.
My work often uses text data from news and social media.
See also my (oldish) research statement
or publications below.
If you are interested in getting involved in research, shoot me an email.
There is a rich set of other faculty at UMass interested in
areas from computational social science
to natural language processing.
See the Computational Social Science Institute (CSSI) website,
and this list of computation+language researchers and courses.
I finished my PhD in 2014
Carnegie Mellon University's
Machine Learning Department,
where I was advised by
Noah A. Smith.
I have also been a
Visiting Fellow at Harvard IQSS,
interned with the Facebook Data Science team.
Before grad school,
I worked on crowdsourced annotations at CrowdFlower / Dolores Labs,
as well as
"semantic" search at Powerset.
I was an undergrad and masters student in the Stanford
Symbolic Systems Program (cognitive science, more or less).
