I am an Assistant Professor at the Department of Biostatistics, Harvard School of Public Health. I am interested in a broad range of theoretical and applied problems in network science. My current research focuses on statistical and mathematical analysis and modeling of social networks and their connection to human health; development of metrics and methods for network analysis; network theory; and online social systems and social media. Prior to joining Biostatistics, I spent two years as a Postdoctoral Research Fellow at Harvard Medical School. I was a Fulbright Visiting Scholar at the Harvard Kennedy School from 2008 to 2009, and before that held a Junior Research Fellowship at Oxford University for two years. I obtained my doctorate at the Helsinki University of Technology (now Aalto University) in 2006, where my dissertation received the Dissertation of the Year Award from the university.
