EDUCATION


Currently I am a faculty member at the University of New Brunswick. I was a PhD student at the Computer Science Department, University of Toronto and worked in the Computer Systems and Networks Group lab. I did my research under the supervision of Prof. Angela Demke Brown.


RESEARCH

My research interests include  
   - Big Data and database management systems
   - Spatial, spatio-temporal and graph data management
   - Parallel, distributed and high performance computing
   - Cloud Computing


I am interested in all aspects of Big Data management, including the management of spatial, spatio-temporal, graph, scientific and bio-chemical data. As part of my research, I  have developed Niharika, a spatial data analysis system for the Cloud. I also built a parallel in-memory spatial query execution system called SPINOJA. Recently, I developed an in-memory spatio-temporal index PASTIS that supports order of magnitude better update throughput than the state-of-the-art, while supporting thousands of concurrent historical, present and predictive spatio-temporal range queries. Previously we introduced a spatial database benchmark called Jackpine, which can be accessed here.

As part of my MSc thesis, I developed a realistic mobility model generator called GEMM. The paper on GEMM can be read here
