I'm a Professor of Computer Science at Wellesley College, doing research on online social networks, multimedia programming, parallel computing, image dithering and CS education. My current projects involve studying the power of crowdsourcing and social networks, especially related to the prediction of political events, and in developing tools that support the privacy of the user while estimating the trustworthiness of the information the user receives.
I studied Mathematics at the University of Athens and Computer Science at Brown. I received my M.Sc. 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 and co-direct 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 lead it to gain FDA approval for computerized tests measuring the symptoms of mental disorders, and a Research Associate at the Developmental Biopsychiatry Research Program at McLean Hospital, Harvard Medical School. Since 2010, I have been on the faculty of the Albright Institute for Global Affairs.
In terms of professional associations, 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, ICWI and ICWSM conferences. 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 German AI Journal (Kunstliche Intelligenz) on Social Media.
My research has been supported by the National Science Foundation, Brachman-Hoffman Fellowships, and Wellesley College.
