I'm a Professor of Computer Science at Wellesley College, doing research on social networks, multimedia, parallel computing, image dithering and CS education. My current projects involve studying the predictive power of social network data, especially related to the prediction of political events, and in developing a tool that will support the privacy of the user while evaluating the trustworthiness of the information the user receives.
I studied Mathematics at the University of Athens and Computer Science at Brown University. I received my Masters of Science and Ph. D. in Computer Science from Dartmouth, and have been a visiting scientist at MIT, the Sydney University in Australia, and at Harvard. I currently work in the Computer Science department at Wellesley College, where I founded the Media Arts and Sciences program, and also at Harvard, where I am an Affiliate at the Center for Research on Computation and Society (CRCS).
In the past, I was the Chief Technology Officer of a biotech company, and helped them gain FDA approval for computerized tests measuring the symptoms of mental disorders. I was further a Research Associate at the Developmental Biopsychiatry Research Program at McLean Hospital. Since 2010, I have been on the faculty of the Albright Institute for Global Affairs.
I'm a member of the Computing Research Association's Board of Directors, a senior member of the ACM, and a member of LACS, IEEE Computer Society, SIGWEB, SIGCSE and SIGACT's Electronic Publication Board. I also serve on the program committees for the WWW (Social Networks Track), AAAI-Web, WEBIST and WWW/Internet conferences and the 40 years of Celebration of the CRA. I am currently on the Advisory Board of XRDS and a Guest Editor for the special issue of the Internet Research Journal on "The Power of Prediction with Social Media" and of the Special Issue of the Journal "Kunstliche Intelligenz KI" on Social Media.
My research has been supported by the National Science Foundation, Brachman-Hoffman Fellowships, and Wellesley College.
