I am a research scientist at Megagon Labs. I received my PhD from CS@Illinois where I worked with Aditya Parameswaran. Before that, I was a lecturer at Department of CSE, BUET.
My research interest lies in interactive data exploration. My work synthesizes techniques from data management, visualization, and human-computer interaction to develop interactive systems that make information space intuitive and interpretable for users to explore. I collborated on research projects
that were recognized with best demo award (at ICDE), featured in popular tech-blogs, and adopted in industry.

Leam is an interactive tool for text data analysis that, backed by a visual text algebra, combines the strengths of spreadsheets, computational notebooks, and visualizations libraries. The visual text algebra supports a number of text analysis and visualization operations.
sheetperf is the first ever spreadsheet benchmark that evaluates the performance of popular spreadsheet systems like Micrsoft Excel, LibreOffice Calc, and Google Sheets. sheetperf also identifies a number of optimization opportunities for these systems.
IncVisage is a progressive visualization tool that reveals “salient” features of a visualization quickly while minimizing error, enabling rapid and error-free decision making. The approach is orders of magnitude faster than the traditional visualization systems.
