I am a senior research scientist at the Data Sciences and Analytics Group, National Security Directorate, Pacific Northwest National Laboratory. I have graduated with a PhD in
Computer Science with a focus on Natural Language Processing, Social Media Analytics and Machine Learning from
Johns Hopkins University,
Center for Language and Speech Processing.
My adviser was Benjamin Van Durme.
I am a PI on DARPA SocialSim program (TA3: Test and Measurement),
and other projects -- Deception Detection and Tacking in News and Social Media, Graph-Based Deep Learning on Real-World Data. Previous projects focused on Deep Learning of Multilingual Distributed Representations from Large Streaming Text Data (co-PI) and Forecasting the Future using Diverse Social Media Sources (co-PI).
My research interests include natural language processing; machine learning; computational social science;
social media analytics; deep learning for NLP applications: forecasting social media dynamics -- real-word events,
opinions and emotions, disease outbreaks, language change, entity and event-driven connotations; deception detection and tracking,
information biases and factuality assessment in news and social media; multilingual social media analysis.
During my PhD I developed novel approaches and practical techniques for streaming personal analytics in social media
focusing on the task of user demographic prediction. I worked on methods and practical applications for
inferring latent user demographics from streaming communications in social media.
I proposed approaches for constrained-resource classification, streaming prediction,
iterative learning and inference with interactive annotation and weighting techniques.
Predictive models developed in my dissertation allow the analysis of the relationships between user language,
perceived psycho-demographic traits, emotions, opinions and interests in social media at scale.
I have been a research intern (summers of 2011, 2012 and 2014) in the
Microsoft Research Natural Language Processing
and Microsoft Research Cambridge Machine Learning and Perception teams.
I worked with Yoram Bachrach on inferring latent user demographics,
personality, emotions and sentiments in social media at Microsoft Research Cambridge in 2014 (demo @AAAI2015).
I worked with
Bill Dolan, Pallavi Choundry,
Chris Quirk and
on learning to built procedural dialog systems with light supervision (published @ACL2013)
and methods to relate literal and sentimental descriptions of visual properties (@NAACL2013
with Mark Yatskar and Asli Celikyilmaz)
at Microsoft Research Redmond in 2012 and 2011.
I was awarded a Google Anita Borg Memorial Scholarship in 2010 and a Fulbright Scholarship in 2008.
I am on a Program Committee for top NLP and AI conferences: NAACL, TACL, ACL, EACL, EMNLP, AAAI, WWW and GHC.
