Two main threads of my work include social media analysis and science impact analysis. Social media analysis aims to extract insights from massive social media data. The image shown above illustrates an example of what one could find through such analysis. Specifically, the image shows the visual results of the year-long Occupy movement in both temporal and geospatial dimensions. More importantly, critical events throughout the movement could be detected through analyzing Twitter streams. Analysis of the rise and fall of the movement could shed light on the organization of the movement, major players involved, as well as the effect of public policies pertaining the movement.
