I am a Moore-Sloan Post-Doc Researcher at the Center for Science, where I am working with Jennifer Jacquet. I am also a visiting scholar at the Environmental Studies and affiliated to the Big Data Group and the Center for Technology and Economic Development (CTED). I completed my PhD from the Department of Computer Science of New York University in the Fall of 2015. My PhD supervisor was Lakshminarayanan Subramanian.

Projects (Past and Present)

  • Identifying Enforcement Gaps in Internet Wildlife Trade
    • Winner of USAID Wildlife Crime Tech Challenge (2016)
  • New and Text Analytics
    • Probabilistic Model for Extracting Events from News Articles
    • Building Event Network for Understanding Event-event relationship
    • Spatio-Temporal Article Graph for Visualizing News
    • Location-Specific Summarization of Climatic and Agricultural Trends: Mining information from the web to collect data about agriculture, climate change, identify and predict the presence of different problems in these areas in a particular location.
    • Structured summarization of unstructured text: In some cases, users search a website where the website text is in an unstructured form. However, the user query is in a structured format. Changing the backend text into a structured form can greatly improve the search quality, search speed and the presentation of the results. This project is aimed to extract key features from such texts and prepare a structured summary of the entire content, taking Craigslist ads as a case.
    • Summarization Search: A Faster Search Interface for Mobile Devices
  • Computation for Food, Water and Agriculture
    • Prediction of Socio-Economic Indicators from News Events
    • Characterization and Prediction of Drought and Water Shortage Issues from Online News: From a corpus of news articles, identification of occurrences and magnitude of drought in different locations and based on past drought cases, characterizing the causes and effects of drought in a particular location. Using these past trends, a model is being trained to predict drought in a particular location given recent news articles from that location. Methodology is based on spatial- temporal relationship analysis, topic modeling and event extraction from the news documents.
    • Estimating Changing Land Patterns from Historical Satellite Images
