* Diverse crowd selection for accurate real-world event prediction"A robust forecast should result from diverse perspectives." Designed and developed several solutions identifying such a diverse set of users from openly available social network data. Published approaches include,- Word embedding, clustering, and multi-objective optimization on social media posts to select an optimally diverse crowd.- Text classification & probabilistic clustering to identify a set of users applying similar forecasting strategies.- Knowledge graph supervised and co-ordinated ascent based network clustering for the improved understanding of social network data. A crowd selection algorithm to assemble a crowd from different communities.* Context-aware Harassment detection on Social media- Developed novel community detection and characterization algorithm to help understand motives of harassment.- A generative model and domain-specific knowledge graph based text augmentation to help online Harassment detection.* India Election 2014- Worked with India PMO team to analyze Twitter data on election to understand sentiments, emotion, and emerging trends during the election campaign. (Covered by four national and international media.)* Assisting Disaster co-ordination using social data- Data modeling using Tweet text and domain-specific data to help assisting co-ordination during disasters. (Four publications)- Domain-specific knowledge graph based inferencing approach to identify causal relations. (published)

* In memory distributed & parallel (multi-threaded) graph query engine developed in C++ - Agile software development Major contributions to the project - Developed distributed and parallel histogram sort, IO utilities, and schema. - Several test modules, bugfixes* Developed Graph processing system for a graph query engine
