I am a student of Remco Chang at VALT (the Visual Analytics Laboratory at Tufts), and completed my PhD qualifiers in Spring 2017. I am researching data systems to support visual analysis of large scale data.
Visual exploration requires that the underlying data be available at interactive speeds. This requirement can be easily met when data resides in memory, but such a solution is not scalable. As the amount of data increases and can no longer fit in memory, the data must be stored on disk or in a remote database. As a result, the queries used to populate the visualization can take minutes, hours or longer to return.
The goal of my PhD thesis is to examine the different strategies that integrate data storage and retrieval techniques with front-end visualizations that enable interactive exploratory analysis of large scale data.
I completed my undergrad and master's at Boston University, advised by Margrit Betke. My research involved analyzing the flight patterns of bats from infrared video. Using image processing, I looked into the flight paths of individual bats and the column depth and density of colonies while they emerged from their roosts at dusk.
