I am an Assistant Professor in the School of Interactive Computing at Georgia Tech. I am also affiliated with the Graphics and Visualization Center (GVU), Institute for People and Technology (IPaT), and the Machine Learning Center (ML@GT) at Georgia Tech. Trained as a computer scientist, I am passionate about problems at the intersection of computer science and social science, and therefore, I build computational methods and artefacts to make sense of human behavior and psychological state, as manifested via our online social footprints. I am motivated by how the availability of large-scale online social data, with the amalgamation of advances in machine learning and grounding in human-centered approaches can help us answer fundamental questions relating to our social lives, particularly our health and well-being.

At Georgia Tech, I lead the Social Dynamics and Wellbeing Lab (SocWeB Lab). We study, analyze, and appropriate social media, responsibly and ethically, to derive computational, large-scale data-driven insights, and to develop mechanisms and technologies for improving our well-being, particularly our mental health. Please refer to the Research page for details about our broader research agenda, and the Publications page for recent research efforts. Our research is graciously supported by the National Institutes of Health (NIH), National Science Foundation (NSF), Intelligence Advanced Research Projects Activity (IARPA), Centers for Disease Control and Prevention (CDC), the United Nations Foundation, Facebook, Mozilla, Yahoo!, and Samsung.

Before moving to Georgia Tech in Spring 2014, I was a postdoctoral researcher in the neXus group at Microsoft Research, Redmond, between 2011 and 2013. I received my Ph.D in 2011 from the Department of Computer Science at Arizona State University, Tempe, where I was a part of the transdisciplinary program and venture on digital media: Arts, Media & Engineering. Following grad school, I also spent some time at the School of Communication and Information, Rutgers. In the academic year 2014-15, I was also a faculty associate with the Berkman Center for Internet and Society at Harvard.
