My broad area of interest comprises computational social science: an emerging field that lies at the intersection of data mining, social science, and human computer interaction. Specifically, my research develops methods to mine and analyze social behavior as manifested via our online footprints. I am motivated by how the availability of large-scale online social data, coupled with computational methods and resources can help us answer fundamental questions relating to our social lives: our actions, interactions, emotions and linguistic expression, both from an individual perspective, at the same time, as part of a larger collective.
In my current research, I am investigating how longitudinal trails of social activity online can be harnessed for better healthcare, particularly in being able to detect and predict mental and behavioral health concerns in people, so as to provide timely, valuable, and smart interventions.
I received my Ph.D in 2011 from the Department of Computer Science at Arizona State University, Tempe, where I was also a part of the transdisciplinary program and venture on digital media: Arts, Media & Engineering. Following graduate school, I also spent some time at the School of Communication and Information, Rutgers University.
